I've got a worn diff input bearing. It's a Ford Sierra diff and the Haynes Manual doesn't say how to overhaul it ("not considered a suitable job for the DIY-er" or some such). Has anyone tried to replace this bearing and succeeded? I wouldn't bother but it rattles horribly at constant speeds over 50mph and I don't want the vibrations to damage the (new) propshaft.

Cheers

I overhauled my diff a few weeks back, its not the easiest job in the world to do but it can be done, just remember to mark the position of everything and take your time. you will need a very long reach socket to get the nut undone on the input (I have one if needed) shaft though.

I bought my rebuild kit form ebay if this helps (around £70 all in IIRC)

Just get a diff from scrappies - much easier!

I can see how to take the input flange off. How easy is it to get the bearings out? Did you use a special tool?

PS, I would go and get one from our local breaker but he is a bloody robber and seldom has anything decent in stock.

bashed hell out of it!

welded round the inside of the outer race and it fell out once it had cooled

Looks live a v shaped race in the Haynes manual. Couldn't the nut be tightened a bit to take up the play (or a shim fitted)?

that nut is highly torqued...

and when you lose it you need to change some components....

its is done that way to be able to cope with the highly side forces!

bearings come easyly out if you can heat
the area arround it, the will will grow faster than the bearing resulting it it come lose...

Tks
