Thread: Diff failing?

Probably a wheel bearing. Best keep your speed down to prevent it from self destructing from overheating the dried out hub. I believe they're not very hard to change over.

Thanks for that. If it's not too big a job to change the bearing I wonder if it is even simpler to chuck some grease into the dry bearing? If it's something I can do on the roadside I might have a go.

D2 bearings are not serviceable to put grease into. They are a hub assembly with bearing

technically .. not really. The bearing is a sealed unit. There is a small access hole for the ABS sensor, but I doubt you could get grease in there to stop the noise.

Bearings can be pretty hardy things if treated well.
I have a D1, so the bearing setup is different, D2 uses a hub assembly unit. Cost about $250-ish or so. Other than the required force for removing the axle nut, it's an easy job with basic sockets and stuff.
You may need a breaker bar and a large socket(32mm, 6point .. from memory). I had to jump up and down quite a lot(105kg) on a 600mm breaker bar to get an axle nut to start moving.

Both my LHS bearings were worn(and I thought it was a diff pinion too) for quite a few thousand klms, before I got the tell tale 'BRRRR' sound on turns too, but I don't drive hard(much!).
I think you just have to be weary and/or avoid of long continuous drives in hot weather. Most of my driving is shorter distances(up to about 200klms) and lightly loaded.

A mechanic should be able to do the replacement in about an hour, maybe less.
If you have the tools, maybe just a tad more if you haven't done one before(and factoring a couple of smoko breaks in there too)

Have a touch of the rims for increased heat after driving. Might give an indication which side.

I thought same recently about a resonance from front of vehicle - turned out to be wheel bearing. Lift wheel off ground and spin it and rock it looking for play. You’ll know if bearing is shot.

If you work out it is the bearing and you really must drive it I’d try to get grease in via the ABS sensor hole. Grease gun without the Zerk fitting should get it in there. Might encourage The 3 Amigos though.

It definitely WILL bring the 3 blighters out to play, I did it on a front hub..
I'm in Casterton if ya make it home Tinggu not to far if ya need a hand with anything

If noise is coming from driversode, going around right hand bends, wouldn't the weight be on left of vehicle,so noise in theory should come from left ??
Maybe a stone or something wedged in between brake disc and backing plate? Just throwing stuff out there
