Title: Rear wheel bearing (estate)
Post by tony on Jun 21^st, 2005, 11:18pm

I had some squeaking from the rear wheels, which stopped when the brakes were applied. First instinct was pads or bearings.

Checked today, and although the pads need changing, they're low, but not to the metal, there was considerable play in the bearing. I could move the whole hub, disc, and driveshaft!

Anyway, I decided to take it apart, and found a whole set of "layers" of hub nut. I presume this is original from the factory, but I've not seen this before. Tightened up the nut and it seems fine by "feel", but I haven't taken it for a decent run yet. Plan to fit a new hub nut anyway, but is there anything I should be worried about, or is this likely to be just an overdue adjustment?

Any and all help appreciated, as we're off on holiday to France shortly (from Scotland!) and I want to solve any and all problems before we go.

Thanks guys.

Tony.

Read the saga of my rear hubs on the main site http://www.fordscorpio.co.uk/rhubs.htm

Suggest you get a new nut from Ford and use strong locktight. If its the nearside as its not handed it does have a tendancy to back off. although at 200ft/lb it should not, but my experiences tell me it does.

Thanks Snoopy. Yes, it is the nearside.

I've read your story, but hope I don't have to go there!

Suggest you get a new wafer nut from Ford and fit it if everything else is OK.

Thanks again, I'll get one today.

By the way, do you know, what is the purpose of the wafer nut? Why not just a solid nut? I've not seen these before.

Tony
As it tightens it expands the layers apart (In the centre) and it acts as a Lock Nut.
Strange Idea really, I've never seen it before.
It makes the 200 ft/lbs or 270 N/mtres pretty critical when tightening, I'm still trying to teach my mechanic that it is B***** tight!!

Thanks Snoopy and Bob.

Bought two today, £6.30 each!

Anyway, my torque wrench goes to 150lb/ft or 207Nm, so I guess I'll just get it as tight as I can and then stand on the extension bar :)

Is it safe to do this with the gearbox in park?

i have just had a couple of weeks of squeeks from the rear of my 2.3, and when the squeeking started, i went straight to my local mechanic, who said , "nothing to worry about, might be a bearing on its way out... come back when it starts growling" so i waited a fortnight, and driving round a corner it changed from squeek, for thud, rumble, and a lot of vibration from the rear of the car.
I went home immediately, and took the car to the garage, first thing saturday morning. Luckily, the garage fitted me in to replace the bearing while i waited.

i drove approx 10 miles from the time the noise went from squeak, to rumble.

Usual thing, wheel off disc off, hub off... ohh! The hub had split all the way round, at the splines, every spline was now a crack, and the hub was fit for the bin.

being saturday, where am i gonna get a hub from? local mechanic goes... Its the same as a sierra 4x4 mate got an old axle out the back.!! ;)

joy of joys.. back on the road in an hour or so, total bill 50 quid cash!

So beware of my tale of woe, if you hear a squeak from the back, get it checked before it turns into a bigger job!

but if it does, an old hub off a sierra might just get you out of trouble

Thanks Donnie, that's worried me!

With regard to tightening the new nut, is it safe to put this much torque on it with the gearbox in park, or is there a another recommended method? There's no chance of doing any further damage is there?

Thanks.

I belive the method is to do it up as tight as normally possible , then stand the wheel on the ground and with Park selected and handbrake on, use the correct torque or the stand on the bar method.
I haven't tried it, but I have been told it works.

Well, as an update, have been changing the rear brake pads on this car before my holiday, and to beggar belief, on the offside, there has been a new hub nut fitted, and it appears to have been tightened with a Meccano spanner. I could unscrew it by hand!

As far as I know, this car has always been maintained "professionally", first by Ford main dealer and recently by a "reputable" garage......

Glad I checked!

On all my cars with the wheel off you can see some white dried paste over the hub, which I take is locking compound. Any sign of some sort of paste on yours.

Hey Tony, So what's that about maintained professionally. by ford main dealer. My main Dealer very large Ford, was fined £4000 plus £1700 cost by trading standards and they had been two years ago. For charging full service rate of £180 and missing out lots of the work they should have done.
I got a super garage now to look after my cars. real nice people and from what I experianced, know more about Ford cars than Ford main dealers.
