Hey guys - ARB lockered rear is clunking around corners under acceleration. Worse turning right than left but sounds like its coming from the left wheel. Happens above 40km/hr up to about 70km/hr (haven't gone much faster around a bend than that!). It doesn't appear to increase in speed with wheel speed either?

I'm thinking it might be buggered side gears or something, but I jacked up each rear wheel and ran it in first gear, dropping the clutch and slamming the brake and couldn't get a clunk sound. Both wheels are smooth to turn by hand.

Rear drive shaft feels solid with no play or clunks when I turn it and the pinion end has a new uni anyway.

Only thing I've not yet tested is going around a corner with the locker engaged, but I don't realllllly want to do that on a dry road - which they are right now.

Any thoughts???

Doesn’t seem likey it would be driveline if its rate doesn’t increase with speed. Although perhaps diff spider gears might (only a guess as their rotation in relation to each other isn’t dependent on wheel speed but I’m not sure how air lockers are set up).

Have you checked all the bushes, dampers etc? If all external bits are tip top it might be time to look at the diff.

Yeah, pretty sure it's spider gears as the diff is nearing 10 years old and is not driven gently.

I was just sorta kinda hoping someone would go "oh yeah that's simple, it's X and won't cost much to fix" hahaha

I've had broken spider gears before (pre-locker) and somewhat remember it being similar (though I shattered them last time so it was a grinding/clunking mess in any direction).

Always the goal!! Haha

Rather than wrecked spider gears could it be a bearing clunk or something?

Unlikely - the rear end is a joeblow full floater.

So ARB emailed me back after checking with their techs and said "Probably not the locker - look at the axles if it's not clunking all the time"

What are the odds an axle has lost its circlip and is moving around?? JML Full Floater remember...
