small clunks? like radio at low volume and you can hear it when turning?

Sounds like the lsd cones are binding, if so, you can use an additive in the diff to prevent it (penrite) or simply change the diff oil with a recommened type.

Sounds like you've rooted your CV joints to me. lol :lol:

Nah... It might be part of the steering linkage that has loosened, bushes or maybe you've thrown out your wheel alignment if it's coming from the front.

My bet would be the diff though. you might have done some damage and now it's not engaging properly when turning left.

What does the handling feel like when you take a bend at speed?

BUGGER - I am currently looking at putting a LSD into my wagon, but have done plenty of right hand burnouts with my standard Futura diff and it's sweet (although I can feel a few mm's play if I turn the wheels by hand when up on a jack...)

Maybe you guys can keep your LSD's and I'll keep my single spinner!

Ho hum, all good...

actually it may not be that bad...

get someone to put it up on a hoist and check the torque screws in your back end...

i had all mine re-tightened after suffering similar clunking from the backend.
everything was fine after that.

the clunking from from backend was intermittent... if you pushed down on the boot rear left you could hear it... almost as if the suspension was creaking..

so yeh, worth having someone take a look. :)


Regards,
Chris.
