Title: Rapid hub bearing failure?
Post by dead-goon on Jun 14^th, 2008, 1:56pm

Hello, I've recently bought a 1997 Scorpio Ultima TDi, it seems like a great car in spite of the slightly bodged-up bodywork. What is it about older Fords and their owners bodging up the bodywork? I prefer to see cars 'as they are'.;D
It drove great on the test drive and on the way home, but driving it to the railway station yesterday I could feel it 'crabbing' on corners then I heard a clonking/drumming noise and it felt like the tyre had gone flat.
On inspection the hub is moving around significantly - is it just as simple as replacing the bearing and should it have failed like that?

Hi and welcome to the site :)

Yep you rarely get any warning with rear wheel bearings, unless you actually raise the back of the car up and check theres no way of telling if its on its way out.

If its that far gone you may need a replacement hub too but its not a big job, I use second hand ones ;)

Thanks for the advice. :D
Do you know how much labour is involved? I'm mechanically inept and will probably farm out the job...

Its only a matter of removing the wheel, caliper, disc, driveshaft nut then the four hub nuts, so eleven nuts :)

An hour tops as long as there are no problems ;)

Quite a lot but it is a relatively easy job .....see THIS (http://www.fordscorpio.co.uk/rhubs.htm)

But its a couple of hours labour .
The workshop manual is also on the main web SEE HERE (http://www.fordscorpio.co.uk/transgen.htm)

Maybe the previous owner bodged the mechanics as well.Is the hub nut loose by any chance ? It should be tightened to 200lb/ft.Failure to do this soon wrecks the bearing and associated parts.As the previous gents said,the job is simple,the pattern part bearing kit is about £30.

Hub nut is fine, it was the first thing I checked. :D
I think I'll give it a go myself, the info on here is very helpful. Thanks chaps!

We all like to be optimistic on this board with new posters but I would have thought a " Mechanically Inept " person would be very wise to avoid tackling rear hub repacement. Good tools and maybe a puller required.

I regard myself as fairly good with mechanical car repairs but I gave up after chewing up the first extremely tight and very rusty hub carrier bolt.

I quite like my knuckles with skin so I paid my local mechanic to do it :-*

I exaggerated, I'm not too bad.
Have some Wurth "Rost Off" nicked from work and an impact wrench so the hub carrier bolts should be easy enough.

Proficiency is the reward of practice and tenacity,ineptitude is the negative result of faint heart and disinterest ! ::) ::)
GOZZ.

Don't forget you will need a torque wrench capable of doing the hub nut up to 200 ft lb - and I would use a thread locking compound.
Also best to use a new hub nut which you will have to get from your local Ford dealer unless the hub bearing kit contains the correct replacement nut which is unlikely.
You will also need some tools to remove the old bearing tracks and install the new ones.
I normally use the old bearing tracks to assist with fitting the new ones.

Most of the pattern parts kits have the hub nut included. It is about 41mm a lot bigger than the original ford one but it is a nylock. I've fitted a few of these and so far they have been OK.
