Title: Rear Wheel Bearing Post by Paul B on Dec 30th, 2004, 4:58pm Evening all. I need to pick your professional brains again, with regard to wheel bearings. One of my rears has gone I think. It doesn't whine, grind or wear the tyres in a nasty way, but when jacked up, I can wiggle the wheel. So, having read this... www.FordScorpio.co.uk/RearHubs (http://www.fordscorpio.co.uk/rhubs.htm) I've now got the procedure in my mind - doesn't seem too bad to me. What I'd like to know is, am I likely to need the hub part as shown on this page or will I get away with just the bearing? Or is it a false economy to not do it all? Thanks... Paul |

Title: Re: Rear Wheel Bearing Post by waders on Dec 30th, 2004, 5:07pm Hi Paul, you will only need to change the hub if it is visibly damaged or if the bearing is a "loose" fit in the middle. A new nut and split pin is a good idea though! 8) ;D 8) ;D 8) |

Title: Re: Rear Wheel Bearing Post by craig on Dec 30th, 2004, 6:18pm paul mine went about 3 months ago,garage did the job for me,and advised the hub was "a little scored" but should be ok,a month later the exact same bearing went again,got it replaced under the warrenty,but paid to have the hub replaced as well.... so far so good and no problems.... so basically if the hub if fine,make do with it,any signs of damage/scoring etc.etc.,change it.... another tip,bearing was easy to get,hub took 3 days,a bit scarce in somerset >:(.............. good luck mate... craig.. |

Title: Re: Rear Wheel Bearing Post by Ultima_Stu on Dec 30th, 2004, 7:04pm I had a 'small' grumble from the rear n/s some months ago and left it for some time - I'll do it later, as you do. Next thing the whole thing collapsed with a major failure (I had been on the motorway heading to the garage not ten minutes earlier) and limped in. On jacking the car up the rear wheel moved a huge amount to confirm it had collapased. They striped it to find only the caliper mounting bracket had stopped the wheel falling off! Parts required - bearing, hub assembly complete, caliper mounting bracket (distorted due to the 'weight' and a set of pads. Sum Total £300+ (with the labour very, very cheap to a friend!) Moral of my story - don't leave it too long, it could hurt all ways. Not sure if this helps but certainly have a very close look as the sound deadening masks an awful lot! |

Title: Re: Rear Wheel Bearing Post by Simmo on Dec 30th, 2004, 9:22pm Paul, A mate and I carried out this procedure and the site gives a very good idea of what is involved. We only replaced the bearing. Take a look at the photograph which clearly shows the securing nut as it is a very large nut and the socket you need is not one the average DIY mechanic would have. Also the torque setting for replacement is as stated around 200ft/lbs and again you will need a larger that normal torque wrench. We did mine ok but I would suggest that after a few hundred miles you re-check the bearing as mine had slackened slightly and needed re-tightening, I was lucky and found this out by chance when having replacement tyres fitted. The proper 'wind back' tool also was a great help in releasing the pistons. Good luck.Simmo :) |

Title: Re: Rear Wheel Bearing Post by Paul B on Dec 31st, 2004, 7:03am Thanks for the advice guys. I have ordered the bits from FordPartsUK (http://www.fordpartsuk.com/) including the hub (just in case ;)) Will look at the size of the socket needed Simmo. Hadn't thought about that, but will get myself prepared. Maybe the slackening off thing was something to do with why Craig's new one failed :-/ Anyway, leaving this any longer is not an option as the MOT is due on the 5th Jan, which it won't pass in this condition. One more question... is the wind back tool essential and, if so, where can I get one? |

Title: Re: Rear Wheel Bearing Post by Snoopy on Dec 31st, 2004, 8:26am The rear hub nut is of a special wafer type FINIS 1008849 and must be renewed only cost pence really also make sure it is tightened up correctly(200ft/lb) and that you use 'strong' loctite or similar thread locking compind... failure to do so will result in the nearside nut coming off again... I know to my cost.... There is not a castlelated nut and split pin on the rear hubs and the nuts are NOT left and right handed like most cars... Its all on here http://www.fordscorpio.co.uk/rhubs.htm |

Title: Re: Rear Wheel Bearing Post by Paul B on Dec 31st, 2004, 8:48am Thanks Snoopy. I had a good old look at your page there. And I've followed your advice and ordered a new retaining nut and all the gubbins. In for a penny and all that ;) Cost is not too bad actually. All parts including VAT & delivery... £127.77 :) |

Title: Re: Rear Wheel Bearing Post by Paul B on Jan 9th, 2005, 4:50pm Well... I got all the parts together, got all the tools out. I even remembered to check during the week that I had the right size socket for the main securing nut (32mm). http://img.photobucket.com/albums/v465/PCBoulton/HubNut.jpg The starting point (and I thought this to be a good idea) was to slacken off that big nut while the car was still on the ground. It is done up really tight after all. So, bracing myself with my big wrench I went to 'crack it off a bit'. Imagine my surprise when it moved just like that. It felt (through the wrench & socket) that it was little more than hand tight :o :o "OK.... well before I go too mad with it, see what happens with it at 200 Nm" A quick click of the torque wrench later and all is well. Wheel doesn't wobble any more. It never did whine, scrape or feel dodgy at all. Only when jacked up could you wobble the wheel. So really, I've fixed it. It was just a bit loose. I only wish I'd checked it before buying the replacement parts ::) |

Title: Re: Rear Wheel Bearing Post by mr._floppy on Jan 9th, 2005, 10:22pm In the old days a wheel bearing was allowed a little bit of wobble , better that than too tight . all you needed was lashings of fresh grease , finger tight on the castellated nut and a new split pin. You've got me worried now , trouble is where the hell do I get a 32 mm socket ? |

Title: Re: Rear Wheel Bearing Post by Richard on Jan 9th, 2005, 10:36pm Out of a socket set with bigger sockets, ;D ;). Or any decent motor factors. |

Title: Re: Rear Wheel Bearing Post by admin on Jan 9th, 2005, 11:06pm My advice is to carry on and do the job anyway - the damage may already have been done by running without the correct nut tightness and it's at least worth stripping it down to check. When they fail they upset the whole back end and that must be frightening on the motorway. I had mine replaced as a precautionary measure at 115k and both were well worn even though it had just passed its MOT. Steve |

Title: Re: Rear Wheel Bearing Post by Badboytunes on Jan 9th, 2005, 11:22pm i had bearing failure on a capri 2.9 of mine. i was racing a TVR along the M4 when i had a vibration :o :o :o stopped at the services for more fuel. pulled off and then my wheel overtook me on the slip road coz the halfshaf snapped! that was scarey and it destroyed my rear quarter panel as well.... |

Title: Re: Rear Wheel Bearing Post by Snoopy on Jan 10th, 2005, 8:07am My advice is.... It it had slaclkened off you have to ask the question .. WHY? something must be wearing badly iside there. and the nut should have been held in place with the strong thread compound... As Stve suggest at least get in there and have a look if it needs doing you have the bits anyway....and if it was only loose put some thread lock on it and re tighten.... |

Title: Re: Rear Wheel Bearing Post by urbanracer on Jan 10th, 2005, 11:17am My n/s/r also became loose,tightened up and all seems ok. Steve collister sent me this Yes you can use the nuts from an X-Type on the scorpio. Whereas the scorpio uses a sandwich type of nut the X-Type now uses a nut with built in washer. This nut has a castle shape and this is what locks it on. I have not got round to trying these yet.has anyone tried this fix? Joe |

Title: Re: Rear Wheel Bearing Post by Snoopy on Jan 10th, 2005, 11:27am It is always the nearside that loosens as the hub nuts are NOT handed on the scorpio they are niormal right hand thread and as such tend to loosen on the nearside with wheel rotation.. Hence the STRONG thread lock... good one about the x type nuts though might have look at those if they are not too expensive. Thanks |

Title: Re: Rear Wheel Bearing Post by Snoopy on Jan 10th, 2005, 7:12pm If the offsaid one is loose then I would certainly check it all out as the offside should really never in theory come loose... but stranger things have happened.... |

Title: Re: Rear Wheel Bearing Post by johnv on Jan 10th, 2005, 7:40pm looking at that picture from Paul B of the hub. This as always done my head in, why the wheel studs only come half way down the wheel nuts. The first time i took off a centre cover and saw that, I nearly had a baby, and I am male. On my 1996 car I have just replace the 7 egg shaped hole alloys which had closed ends nuts with the 12 spoke wheels and that the same when I put on the open end nuts. ---------------------------------------------------------------- I alway have my repairs done at a garage as I am a retired person, I worked hard all my life so I did not mind paying others to do this. So I ask the question, is there not a tag washer under the main wheel nut, that after trighting the nut to the correct torgue, you can bend the tag over to lock the nut. What I have been reading about wheels about to fall off the car, I don't think I dare risk going above 30 MPH any more |

Title: Re: Rear Wheel Bearing Post by OHC on Jan 18th, 2005, 11:24am Hello! I had to replace two rear lower arms due to accident damage! Of course mechanics removed hubs and tigtened nuts (new!) again! Before that both hubs were OK! Shortly after the replace the same mechanics noticed that both rear wheels wobble! They adviced to replace both bearings! But bearings never die at the same time! I saw they didn't use any thread lock compound and may have apply incorrect torque! I'll try to re-tighten the nuts! It may help - far better than replace bearings OHC |

Title: Re: Rear Wheel Bearing Post by Paul B on Feb 13th, 2005, 7:50pm Finally got to the dodgy rear wheel bearing today. When I took the hub carrier away from the vehicle, little bits started dropping out of it. Yep, it was the bearings! :o The bearing cages had broken up and all the bearings were all over the place in there. Had a good old look at the instructions on the main site for this, but was unsure of exactly how things went in there. My plan was to take it apart and just put the new parts in as the old ones went. But as things were so broken up, I couldn't really tell. I've taken educated, common sense guesses but have come to a halt. I've got the bearings and the seals back into the hub carrier, but I don't want to put it all back on the motor if its not quite right. Have taken some photos of what I'm left with. Can someone who knows tell me if it looks right? Photos Here (http://www.anyboard.net/autos/cars/scorpio/index.html) ( Check "Today's" listing ) |

Title: Re: Rear Wheel Bearing Post by Badboytunes on Feb 13th, 2005, 9:00pm Hi M8, from what i can see the bearing looks good in the hub .......... As long as it is driven all the way "home" and sits square in the hub , i forsee no probs. Any second opinions? Cheers Nick |

Title: Re: Rear Wheel Bearing Post by Snoopy on Feb 13th, 2005, 10:48pm I agree looks good to me... just double check the hub itself... thats where I fell foul the first time I did it, did not double check it for wear as can be see in the write up I did.. Good job.... |

Title: Re: Rear Wheel Bearing Post by Paul B on Feb 14th, 2005, 12:02am Have got a new hub at the ready. The old one was quite badly damaged from all the little bits knocking around in there. The thing thats bothering me is that now I've knocked those all together, I'm finding its all so tight that I can't spin the new bearings ??? Shouldn't they be all nice and free? And.... at the front of that hub carrier, where the 'spigot'(?) of the new hub goes in... well, the spigot is 40mm long. But from the front face of the outer bearing, it seems to be 51mm before the inner bearing. So it seems to me that the inner bearing won't get touched ??? I'm very confused by this and thinking I've got something wrong. Is it possible to get them the wrong way around? Sorry for being such a chump with this, but like I said I was expecting to use the old stuff as a pattern. Wasn't expecting it to all just fall apart. In this picture >>> PIC (http://www.anyboard.net/autos/cars/scorpio/posts/341.html) <<< the bearing cap is home as far as I can get it. I'm thinking it sticks out too far? I don't know :-[ |

Title: Re: Rear Wheel Bearing Post by Snoopy on Feb 14th, 2005, 8:05am Looking It that picture it does appear to be protruding a fair way out... One question.... Did you hammer the new bearing caps ALL the way home..... They do take a lot of force to drive in all the way and then the bearing just drops in.. should all be nice a free and clean and then if I remember correctly the seals fit in .... should all be flush with the outer surface of the carrier .......... It does not matter which bearing goes where the two are the same..... |

Title: Re: Rear Wheel Bearing Post by Paul B on Feb 14th, 2005, 5:31pm OK, well I had a sleepless night over this last night, so I've decided to knock it apart and start again. I've managed to get new seals because they're bound to get bent in the process. I dropped the bearings in and they seemed nice, but since knocking home the seals, they've gone tight and I can't rotate them. As for them being hammered right in... well I'm scared to knock it any harder. No, I think I better start again. The car will just have to spend another night/day up on stands :( Thanks for the advice so far though :) |

Title: Re: Rear Wheel Bearing Post by Paul B on Feb 18th, 2005, 6:55pm Well... erm... it wasn't one of my greatest successes really :-[ I spent days (or evenings actually) out in a tight for space, poorly lit garage trying to get this hub & bearing together. The old stuff was in a bad state. And when I was checking things for size, I noticed that not only did the new bearings fit easily onto the old hub shaft, but they kind of rattled on it. Compare that to the new hub and it was a whole different ball game. That was a tight fit! :o Tighter than a ..... well, I can't say on here ;) It had me wondering if I actually had the right bearings (couldn't compare them to the old ones as they simply fell to bits). Anyway, after about evening number 3, I gave up and decided to take the parts to a garage, hoping for them to assemble the parts for me to take back home to fit up to the car. I left it with them for the day, but when I collected them I was presented with a half finished job (they'd given up too). And last night, in a really wound-up state, I went all out for it and gave it what I thought was one hell of a beating. And... I did it! It went together. I got it back on. The wheel spins. It doesn't creak any more. I have a Scorpio again! And that makes me a happy bloke :) :) But I've learnt something here. This job wasn't as easy as I thought it would be. And if the other side needs doing, I'm really not sure I'll be doing it myself :-/ Maybe I need more or better tools. And a better environment for doing the job. Or maybe I'd just be better off doing my work and paying someone a few quid to do the bearings. Paul's Comment: Not a job for the limp-wristed! |
