Rear diff rebuild...needs to happen but........
« on: February 01, 2009, 01:25:47 AM »

Hi all,

The rear axle (well think it's the rear) despite having some additive and oil change won't calm down with the clonking noise when pulling away after haveing done a few miles...stopping at a junction and then the clonking for a few seconds as I pull away.

Those in the know reackon it's the cluth packs. So in the absence of anyone who knows how to do these anywhere near me who know how to do this I'm going to have to do it myself with the assistance of my step father who has rebuilt few a landy diffs in his time.

So questions are:

1. is it feasable to be able to do yourself?
2. what are the pitfalls / hazards?
3. should I replace bearings or anything else?
4. anyone know the part no.s for a rebuild kit?
5. Anyone want to earn some money rebuilding my axle who know what they are doing (i'm not kidding here).

There was a guy proffering his services for this sort of thing on ebay but has disappeared (near whipsnade zoo I think).

Anyway all help appriciated and anyone who thinks they can do this drop me a PM...i'm willing to travel.

Cheers

I've never done one, so might be talking arse ;) but, the clutch packs for the lsd can be picked up from ebay for about a ton, it can be done at home since it's all torque settings a feeler gauges. You wont need to reshim the diff, but if your stripping it that much you might as well stick some new bearings in and have it professionally adjusted up. Worth a quick call through the yellow pages for that, and it's not a back street garage job, go to a diff specialist.

If anyone tells you you can rebuild a diff (reshim and set backlash) at home from the book of lies with nothing but some tipex and feeler guages they have been very very very lucky.

Try adding two bottles of friction modifier and do the "figure of eight" driving in the car park to distribute the stuff...........worked for me, but as I put a truetrac in about a month later I cant say if it would have lasted longterm.  If it does you got a cheap fix at about a tenner.

you need a bit more than tipex and feeler guages, but with a dial gauge, some basic tools and a bearing press it can be done at home, I know becase I am doing it to my CJ now.

ive now done quite a few diff rebuild/regear now an once you get the hang of it an get your head arround what your doing, then its pretty easy.

if its been a road car all its life, chances are it'll be fine just pull the diff out, replace the packs an shove it back together (obviously making sure they are set correctly by the book)

if the diff almost falls out instead of being a bit of a pull, then you'd need to have it set up, as chances are the bearings are worn and cos of the free play, so are the shims! otherwise just replace the clutch pack.

if you're going to set it up, you'll need the shim set, a DTI, and a micrometer, and prefferably the proper marking compound(dulux does work but isn't quite as effective) aswell as the guide to what are the correct an acceptable patterns.

don't let a landy person touch it or tell you he knows what he's doing, as they are compleately different to set up an a landy diff is probly the easyest thing in world to do!!!

its also not advisable to reset an already meshed ring an pinion as chances are you won't put it back to how it was, an it will prematurely wear out!
