Thread: Exciting driveline sounds and smells

front driveshafts make some very unusual noises before they appear to be u/s.

for the sake of 15-20 minutes undoing 8 bolts with 13mm spanners I'd be dropping it out for a look.

if you don't have the wear with all to strip and inspect the uni's/splines and then lube everything with high quality grease , take it to a drive line specialist.

I'd be thinking the TC... Is it in ALL gears or mainly the final drive gears?

I had something very similar happen to me on my last year major trip crossing the desert off-track. Mine started 1st day out and had me concerned to the point that I would not drive in 6th gear as that was where the noise/whine seemingly originated from. The noise wasn't there in any other gear at that point. For most I the trip I just kept driving in 5th gear. After a few phone calls to various LR Mechanics, I dropped the GB oil to checked the state of the GB oil which was still like brand new. I refilled the GB with Nulon full synthetic 75w90 oil along with Nulon's G70 oil additive. By the time I had completed the Googs Track and hit the Hwy & headed up to Coober Pedy the noise appeared to be gone or greatly diminished. Unfortunately, the drive from Coober Pedy to Kulgera the noise returned. Again, by the time I had reached Birdsville and again headed north the noise again seemed to have gone/diminished. When it was time to head homewards along the Hwy again I noticed the noise had returned but this time I could also start to hear it in 5th slightly. I made it all the way home w/o any issues and still haven't gotten around to investigate the issue but the noise is nowhere as bad as it was but now I can hear it in 4th >6th gears.

I'm now thinking it's the TC and have purchased a rebuild kit along with a ATB for the centre Diff. It's just a waiting game until a mate & I can find the time to rebuild the TC....

If you get to find out for sure what your issue is, I'll be greatly interested to know...

cheers
