i thought it cud possible b uni joints. sort of sounds like something is loose and vibrating. i redid my gearbox mounts thinking it could be that but did not solve anything, i have replaced gearbox oils and still not helping. i have a 3inch sus lift and 2 inch body lift. will that affect my uni's? and if so what symptoms should i look for?

i did regrease all nipples on my unis about 500km ago.

I just had a similar problem. Replaced my centre tailshaft bearing, rebuilt the transfer, changed the CV's and wheel bearings, installed a new clutch, and it still didnt fix it. Turned out to be the locking hub mechanism snapped a spring and was rubbing inside the hub. Pissed off that it was such an easy fix after all that work, but at least the Lux is good to go for another few years :armsup:

Put it up on stands and see if it will still make the noise. You can load it up a bit with the brake if it helps. Get someone else to look and listen and you should be able to track down the problem pretty quickly.

You can get a bad rattle from some cars drivetrain if one free wheeling hub is locked and the other unlocked when driving in 2WD
