Outer Limits 4x4 Board

hey guys, i have this loud rattle coming from what appears to be my gearbox. on able to hear it when in 3rd or 4th accelerating and deaccelerating. doesnt happen when u keep the car at a constant speed. any ideas?

need more info .stab in the dark its your rear diff

Maybe uni joints?

mine did similar to this a few months ago, although wen coasting down hills it was worse. rebuilt the transfer put it back together and problem solved.

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

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.

what sort of gearbox?????????

g52 im pretty sure, stocko box that comes with rn105 hilux

ok well if she is a bit long in the tooth maybe a it wants a new set of bearings thru it

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
Easy to check

bit long in the tooth??

ohhhh haha, sorry, i understand now. thanks:)

my 80 series is doin that at the moment and ive got a 3inch lift in it. i found out that its me transfer case if ya transfer has a magnetic bung in it drop the oil and see if there is any metal on the bung or in the oil.

but my lux makes the grinding in 2wd?
