rear axle noise

1990 GW 360 just rolling over to 100,000 ( or maybe 500,000- who knows)

As the title says mines not 100% quiet whilst driving. Its not too bad yet but what am i in for when the crunch comes? I dont think the whine is transfer case or tranny, defo coming from the back. Makes a slight groan at 20 ish and slight whine at 40- 50mph. Whats the re-build work, and can it be done at home or do you need special tools/ pullers / kit etc? If anyones done a rebuild do you have pics? thanks guys- would like to try the cheap way if poss.

Does the noise or the pitch of the noise change when rounding a corner or turns? If so I would be looking at Wheel Bearings being the problem. They are pretty straight forward to change, no special tools required.

A whine or a groan?

Mine had more of a metal rattle, like loose shocks bushing, or loose shock mount.

Do you have oil in it? 100k is a probably right. The 74 had the rear wheel bearing redone at 120K then 320K..... the 85 last week at 202K. The bearing were both very loose. After the first drive.... I have noticed a gain in power.... or a lack of resistance that gives me a lot more power.... subsequently, it rolls very well... I noticed that spinning the wheel lasted a lot more than before.... it usually stopped right after I took off my hand from the tire, now it lasts a bit more, no change in mileage.... but it is a lot more fun to drive.

Try to put the rear axle off the ground with suitable jack, grasp the wheel and see if you can detect the same noise by trying to yank the wheel off its axis from both the vertical and the horizontal vector, a bit like checking a cv joint.

Back to the whine or groan, this could be the carrier bearings? but someone will chime in.

Id jack the rear up put it in neutral and see what kind of lash you have on the Pinion. turn it back and forth and see how much play it has and if it turns over smoothly or in a kinda grabby fashion. If its a ring and pinion, I would let someone else do it, but wheel bearings arent too bad on your own. again, if start messing with the carrier, ring and pinion it can get complex, nothin you cant do. Its just tedious and definately requires kinda special tools.


P.S. for the Gas bill a GW in the UK carries, a rear end rebuild is cheap!

Noise doesnt incease in corners at all. Could be the wheel bearings, but sounds more like noise from crownwheel and pinion- i will jack up and have a pull on both rear wheels. I topped up the oil about 4 months ago- did take some but not too bad. I do get a clonk when going from forward to reverse. problem is trying to find place that can do- may start looking around.

Re the noise- nothing like my XJ when that needed rebuild- now that was bad!
