Noisy Diff....ARRGGGHHH
clairetoo - 15/6/08 at 08:49 AM

I finished off fitting my `new` 4.1 diff Friday night , along with new wheel bearings , and took it for a proper test yesterday................... and DAMN it whines
I bought a re-build kit off fleabay ages ago , I`m wondering how much of a job it is to re-build a diff ?
Or does anybody know of anyone in the Leicester area who would do it for me , with me supplying the bearings ?

I've never done it, but I don't believe it's a question of whether a diff rebuild is too difficult, it's usually that you get half way and then need a specific tool. So if you are any good at making tools for the job at hand, I'd give it a go!

i need to rebuild mine.

Fostek want £150 labour £170 bearings then I am looking at over £100 in transport costs to get it there and back.

I am going to have go myself I think.

just got quoted £225 to replace bearings on mine, gonna have a go me sen I think!!

the issue is setting it all up properly, and to be honest, £200 is money well spent!!

To do it at home, even with decent engineers kit, is not really feasible, and if the bearings need shimming to set the side loads etc, then you have to pull them off again, which is a bitch to do (this is assuming live axle not sierra diff)

Even the sierra diff requires a prestress bar fitting to the casing to load it up when setting the bearing preloads

This isn't going to stop you getting to Newark is it?

Nope.......cuz I've just re-built it myself
And to be honest - it aint rocket science , the hardest bit was getting the old bearings off !

I'm with NS on this one, get it done properly by someone who a) knows how to do it and b) has the right tools and parts.

I watched a specialist rebuilding a TR7 diff (it was for an article I was writing) and there is a lot to it. Sure you can replace the worn bits but it is getting them in exactly the right places, and getting the pre-loads right which is the difficult and essential part of the operation
