G'day

I've noteiced that the rear diff seal leaks from behind the tailshaft flange. Mostly when workin hard. I had a little vibration on driveline. I install axle castor shims and vibration were gone. I moved axle backwards for about 17mm, installed new springs and anti wrap bar, and I have a lot of vibratons on driveline. I though that my tailshaft is to short now, due to castor angle shims and new springs. I installed spacer but it still vibrates.t I can't be the angle (it's double cardon one) and it's not too short. I've noticed that there is a play on the flange. In that case it might be the bearing. I know that there are 2 in the diffhousing, big and small. I've read somewhere on the forum that I is easy to stuff up things with the diffs.

What do you think? Do I have to rebuild diff or it's just bearings, Is it hard to do it (apart from undoing that big flange nut) or should I have it done by diffs specialist and if so any ideas how much could it cost?

cheers
Chris

when you say there is play in the flange, do you mean rotational movement (about 1/8 of a turn can be considered normal) or do you mean up/down, left/right movement,if this is the case then the bearings are shot and the diff needs rebuilding.

If you don't know what your doing it would be wise to get a professional to do it for you. setting the preloads and backlash is not a job for the inexperienced and you need a few special tools.

it may be easier to find another diff centre and drop it in. chances are if the bearings are flogged out the gears might be stuffed anyway.
