Title: Rear bearing
Post by Chieftain on Oct 18^th, 2010, 3:37pm

Would people agree that a noise like a washing machine going round, add to that clunking sounds and others, would be an indication of a failed bearing. Think it is as it was an advisory back in July MOT.

I've seen and heard of the torx bolts slacken a few times, still not sure if its because of work carried out previously or that they just do it sometimes but worth a look, usually the diff end joint

If you had an advisory on the wheel bearing you need to get it fixed asap :o

Clunking - sounds like a CV joint to me - they can't be tightened, you will need to replace it.
Not a difficult job, done a few in my time. Think you can pick new ones up for around £35 but I normally strip down used ones, clean them up and put them back together.

Yes new pattern part CVs about £30ish,the 16 valve engined joints are smaller than V6s and diesels,and the latter have thicker bolts.
If your bearing is disintegrating Chieftain you should be able to jack the wheel off the ground and detect considerable play by waggling it top and bottom,if that is the case, the hub and possibly the carrier will be scored and needing replacement.

Bit confused now (easily done) jacked it up checked for undue movement and seems to be none, cv seem alright to me, no noise in reverse, took it for a very sedate drive up and down road and again no noise, anyone any ideas?

Chieftain.
How did the MOT bloke deduce you had a wheel bearing problem ?,if there is no slack,it is difficult to spin the wheel to feel for roughness as the diff prevents it,if the bearing was really rough you MIGHT feel something when the wheel was turned.A worn CV joint makes most of it's noise under power,and may be difficult to detect whilst jacked up unless it is very slack.You may possibly bring something to light by jacking the wheels under the suspension arms and running it in gear,sounds transfer through the drive train and it's best to use a stethoscope to locate the source.

Gozz they detected by feel, said there was slight binding (not sure if that is the word they used) tried again later today and I think it has gone awful noise from hub area, but it is garage bound next week.

check the rear brake pads/discs you may of had a sticking calliper or some grit stuck between the pad and disc

My near-side bearing had no-play whatsoever, but it was making that exact whirring 'washing-machine' noise. I changed it as a matter of course, and it certainly needed it! When taken apart it was a s dry as a bone. Fortunately at this stage I was able to use the old hub & carrier, not so with the off-side I replaced only a fortnight before, I just bit the bullet and paid £100 ish for a new Ford hub. If you spin the wheel fast enough you'll hear the hub 'moaning', the best thing to do is compare it with the good side by having both side on axle stands.

If i can get it to the garage next week I will post and let all know the fault, not driving it I add, but it will need flat bed or rear suspended tow.

As things like CV joints, propshaft UJ's and like that, have a bunch of needle rollers at each little bearing, seems to me when they start to break up it goes downhill fast, like maybe in minutes

No roller bearings in the CV joint - just 6 large ball bearings.

or in the UJ's, I think you're confusing them with wheel bearings Mike?

Nope, I obviously know nuffink about what's in a scorpio's joints lol

Well the job is done, the bearing had collapsed, but the only damage to the hub seems to have been caused by the last garage to fit that bearing. Thhis one has cleaned everything up and checked it out.

Any Scorpio owners in Gloucester I can reccomend "Gloucester Servicing and tuning centre.

Make sure they tightened the nut to 200lb/ft.

And get them to re-check it after a couple of hundred miles. They have been known to slacken off once on the road. :)
