How to change bearings

Guest

New member
How do you change the rear wheels bearings? The inner ones. The outer ones are straight forward but do you attack the troublesome inner ones from the same angle, I.E. Take the outer ones out and keep going. Or do you get under the car and take them out from the back? I've got everything stripped ready to go, CV joints are off, drive shaft etc.
AND, when i order them are they a general 'one size fits all' or are there differnt sizes for different years or whatever? I've an 82 Lux.

Cheers Amigos.
 
Darren,
its all one bearing at the back, the fronts have inners & outers.(I'm assuming its basically the same as my 944T) To remove the bearing you need a puller set. If you read the bumpf, the trailing arms should be heated to (200?degC) and the bearing pressed out.

Therefore your OPC should manage it for about a grand each side ...Sir.[:D] Sir[:D] (one for each side)

I have done 3 bearings now with a good puller set.
Pressing in the new one needs care and a big threaded bar (M20) with thick plates to suit the inner of the bearing.
Allow 3 hours for the first one and 15mins for the rest.[8|]

RULE 1 - You do not need a hammer.
RULE 2 - You need the right puller set as the average monkey metal (Halfrauds) set will bend or strip the thread.

You have done 80% of the work getting to them.

The bearing comes out towards you as you view it. It will break and leave the inner on the splinded hub as it comes apart.

Try Clarks garage for step by step instructions. Sorry I can't recall every detail.

944T

 
Thanks George. I think the 944T must be different because what you describe doesn't sound familiar at all. If I'm sitting looking at the rear corner, with the wheel and everything else removed and only left with the stub axle sticking out. I can push the stub axle out through to the other side and then I'm left with a set of bearings a long spacer and then another set of bearings on the other side. I can get the first set out (The Outers) and the 4 or 5 inch spacer, but then i don't know if the inner bearings come out the same way or if i knock them through. I think I need to pull them towards me.
I'm worried I didn't need a gear puller though to get the stub axle out. It just pushed through with very little resistance. Just good luck or is something amiss?
 
C'mon, there must be someone who likes getting muck under his nails and has done this before.
I was lying in bed last night thinking about it and the reason i thought the inner bearing came out the same way as everything else is when i was under the car i couldn't see how the bearing would come out from there, ie from under the car and pulling towards me. There seemed to be metal stopping it. But thinking about it, maybe that metal was a snap ring. If so I'll just need to remove that and then the bearing will either pull out or I'll be able to tap it out through from the other side.
I really need a Haynes. But surely someone has done this at home before. Please help guys, i need this sorting.
 
early cars with steel trailing arms have two bngs with a spacer between, fnt comes out from front rear comes out from rear. ALL 944 with alloy trailing arms have ONE bng with two races in them this comes out as one unit and must be driffted or a puller must be used
 
Thanks Bert. And thanks Knightma for the link, that clarks-garage is spot on. Easy to follow and understand. I'm keen as mustard now to get in the garage. Tally Ho!!!
 
You`ll need a massive torque wrench or find a friendly lorry/coach repair yard who will lend you one as the rear lock nut is 300 Lb ft IIRC [8|]
 
I'm way past that hurdle mate. I used a 3/4 drive breaker bar and a three foot scafolding bar for an extension, CRACK, get in there!!!
 
Make sure you do it up to the correct torque as it's not nice to be in a car when it starts coming undone [:eek:]

I'm speaking not as someone who has done it, but someone who's been in a car as it loosens!
 
Wahey!! Job done. And what a difference too. I'm now basking in that inner pride feeling and also the £400 the shop would have charged.
Anyone need there bearings doing? £150 sound good?

But you DID use a torque wrench, right?

Only cos at JZM a h/d torque wrench with a 4 foot bar with a mechanics full weight on it with me in the car with the footbrake on and the handbrake on was the only way to get the required torque without actually moving the car!!
