Title: Rear Wheel Bearing....again!
Post by mindofitsown on Oct 22^nd, 2008, 1:25pm

Offside rear wheel bearing has gone again. Admitedly last time I replaced it complete with housing from a dump because I couldn't get the old races out. This time I want to do it properly. So, three questions:
Anyone know how to get the races out of the carrier?
Anyone know where to get a replacement kit?
Anyone know why these bearings fail so often?
Regards,

The bearing caps can be knocked out using a drift and the most common cause of failure is incorrect fitting OR poor quality bearing sets .
The bearings are standard fitment the same as used on the granada the hubs are a FORD only part.
I did a write up on the main site which might be helpful HERE (http://www.fordscorpio.co.uk/rhubs.htm) and also the WORKSHOP HOW TO (http://www.fordscorpio.co.uk/manual/suspension/RWheelBearings.pdf)

Do you mean you fitted a complete assembly from a scrapper ? if so did you not ascertain the condition before fitting ? As Snoopy says,the races can be tapped out using a drift or blunt punch,best to tap alternately at 180 degrees to obtain a level movement.Examine the hub and carrier for wear and scoring.To tap in the new outer races,grind a few thou off the old ones to allow for full seating,and use them as a dolly,you will know when they are fully home by the solid sound,give them a couple more taps fo surety.The bearing kit can be bought pattern part for about £35.00,the nut they supply is a big horrible self locker with a bigger outer size than the proper Ford nut.They work OK but necessitate two sockets for one job.I have used old Ford nuts with no trouble,but it's not best practice.Torque is 200 ft/lbs,you can't damage the bearings because they are pre spaced in the hub carrier.It's best to use a torque wrench because undertightening could be a disaster,and if you guess it with a bit of scaffold tube,you could fracture the drive stub and loose a wheel at a later stage.
Best O luck

In addition to the latter Use STRONG thread lock on the wafer nuts as the threads are not handed and the n/side one WILL undo even at correct torque, under some conditions. IF you fail to. I know as it happened to me the first time .

Further addendum :- If you mark the nut and thread with a spot of paint or gasket cement,you can keep an eye on any movement.

Many thanks all.
Yes Gozz I'm ashamed to say it was a complete assembly from a scrap car though I checked the bearings as best I could at the time (wheel rocking, smoothness of turning etc). I only did this to get out of trouble quickly and it lasted about 2 years plus so not bad for a tenner.
I have since found the original bearing housing with race caps still in it ....and guess what....managed to drift them out using an old brass toilet valve body I found in the garage! (Cistern valve now unuseable needless to say). Original race caps both quite pitted with blue marks from overheating....crikey!
Now to find a bearing kit and continue. I will follow your advice re torquing, locking compound and paint marking. I too have had the same nut undo itself several times over the years (both original and replacement bearings) despite applying exactly the right torque and using different nuts. Luckily its always been at slow speeds but its very worrying to think what would happen at 70mph.
Regards.

Always fit a new nut available from Fmd, about £4

Will do Pete many thanks. My local FMD quotes £65.40 for the kit and confirms it comes with new nut.

Took it all apart this afternoon in readiness for new bearings. Oh my god, you should see the state of the hub! Its got an enormous guage in it and cracking all the way down the splined shaft, so its another £81 for a new one. :'(

I have a used one for £25 +postage . It was advertised on here for a while .
Bearing kits from your local motor factor will be a lot cheaper than a FMD and use the same bearings. Most likely SKF bearings and the wafer nut I have one of those brand new if required . Pictures available

Sorry for tardy response but PC off air for a while. Many thanks Snoopy for the offer but I realised I already had a spare in the garage which I got from the dump when I got the bearing housing some 2 or 3 years ago.
Latest is that that the hub is all done now so many thanks to everyone for their advice.
I would like to send some photos of the damaged hub as it may be of interest to some but I don't know how to attach photos......can someone educate me on this please?

OK you need to host the pictures somewhere on the internet, Photobucket or similar do a free ghosting for pictures then put the location of that picture in the message body between the [imghttp//: etc etc .com[/img] and then post the message as normal
Please make sure the picture size is NO BIGGER than 640x480 pixels and it will appear like those that I attached .

If you use the reply button and NOT the quick reply at the bottom of the posts it gives all the icons for things and the insert picture forth from the left on the second row

Many thanks Snoopy, I really appreciate the advice but I think the education I'm after is even more basic than that cos that went over my head. I can attach pictures in Outlook Express if that helps.
Regards (now I feel well behind the times!)
