Title: Rear Wheel Bearings
Post by Danny_R on Mar 29^th, 2004, 10:42am

Hi Guys,

in a bid to try and eradicate an annoying droning noise to the rear of the car, I’ve decided I’m going to change the rear wheel bearings. At first I thought the cause of the droning could be something as simple as the wheels but I’ve since replaced the aging tear drop type alloys for the 12 spokes, the noise still remains. I next suspected the diff so I checked the oil level but its fine. I’ve even taken the back seat out and had a friend locate the drone while in motion. it appears to be coming from either side. I’ve checked for play in the bearings with the wheels off the ground but all seems ok. My scorp is an early 95 saloon with 111000 on the clock so I guess replacement bearings wouldn't harm.

I have read the write-up on the site about changing the bearings. apparently can be a real sod to separate the bearings from the hub! does anyone have any tips or experience on this? a local mechanic has quoted £40 a side all in. does this sound about right?

Any help will be much appreciated :)

BTW I’ve also noticed the rear passenger wheel appears to taper in slightly at the top when looking from the rear. Although this is very slight could it be something to do with the bearings? I have swapped wheels round but it remains ???

If its any help ive had two Mk3's with a drone, the first one only occured over 40mph and turned outto be a missing balance weight off the propshaft causing it to resonate.
The second one did it all the time and turned out to be the propshaft centre support bearing dried up.

(having said that i cant remember if the scorpio has a split propshaft or not! I try not to look under mine less i have to!!) :)

Hi Andy,

I didn't even think about the prop shaft. The scorp is the only RWD car I’ve had. The droning noise seems to increase in pitch the faster the car goes. It appears to come from either wheel but I suppose the sound could be travelling. I don’t get any jolts when taking up drive or clunks. I think I read somewhere about later scorp’s having revised prop shaft mountings. maybe mine wasn't fitted with the re-designed ones?

please keep the posts coming if anyone has any ideas :)

Kind Regards

Danny R

certainly sounds like the propshaft bearing i had in my mk3. couldnt tell exactly where it was coming from but as you say, it travels, it used to increase with speed too, if i drove alongside a high wall with the window open you could really hear it then.

best of luck anyhow!

Hi Danny

If a mechanic offerd to do mine for £40 a side all in I would have bite his hands off give him the readys and let him get stressed insted of me. I think I payed £30 ish each side for the bearing kits alone. So £40 a side is a bargin.

Good luck.

Having just done my rear bearings I have to say it was fairly easy. The initial pain was removing all the brake parts etc.

The MAJOR pain was finding I had to replace the hub as well,it was to worn/corroded to hold the new bearings.

If the old bearing centre race is stuck to the hub then a bit of gentle heating and progressive tapping will remove it fairly easy.

PS. Dont do what I did and put the seals on te wrong way round!The rubber bits should face away from each other [ bearings] and not ]bearings[ :-[

If you do decide to to it yourself,when reasembling put the bearing in the fridge/freezer for a while and apply some heat to the hub as putting together. You,ll be surprised how easily they fit! john.n ;)

Hi Andy, Alan, Eddie, John,

Cheers for the help and the tips guys ;)

I think I may do the bearings regardless. Just out of interest, this prop shaft bearing, is it expensive and is it an easy job to do? is it likely to suddenly collapse if I don’t tend to it soon?

Sorry for all the questions, just want to make sure my car makes Derby ;D

Kind Regards

Any bearing noise is not good news,as in my experience you just cannot tell when they will give out! Ihave driven cars with noisy bearings for thousands of miles just to hear them get noisier.By the same token they can fail without warning,especially on a long run when they tend to get hotter. Best advise i can give is if in doubtreplace it. john.n ;)

I agree with John

If you have any bearing noise Get it sorted asap or it will cost you big time.

Hi all!

Just a spin off on the prop balance thing, the prop on 95> scorpios is balanced by the use of different weight pinion flange bolts there are 15 different sizes available.
Fron the plant they were matched for the individual prop so must go back in the same hole they came from if removed.
I know it isnt what you asked but may be of use at some time!

I think the propshaft bearing was about twelve quid but then again that was on a Mk3 so dont know about the 95+.
The balance weight on that one was just a small square plate bonded to the shaft (or rather, wasnt, in my case!)
