Strange 'moaning/squealing' from rearend

[smaddock]

And yes, thats the rear end of my car!! :yeah:

Anyway, for about 3months I've had a moaning/squealing noise from the rear end which is not noticeable when driving straight, but is heard when turning left around a corner. It doesn't happen all the time, but is getting more regular.

At first I thought it was a bearing prob, so thought it was a good time to have the diff rebuilt with 3.9 gears and LSD centre, and obviously new bearings throughout, including axle bearings.

However the noise is still there. Is there anything else it could be? The car has been lowered with superlow kingsprings, so I was thinking maybe it could have something to do with rear end geometry. It doesn't sound like tyre rubbing noise, but then again I haven't really checked for it either. I have also heard it could be something like the brake pads draging when going around a corner...?

Any ideas?

change oil in diff
or replace clutch pack

 

[kowan]

Did you check the boot to see if anyone was in it?

 

[smaddock]

Yeah, there's definately no one in the boot

As for the diff oil and clutch packs, the noise was there before the diff was rebuilt with LSD and 3.9, and the rebuild only happened 2 weeks ago and the noise is still there.

maybe a suspension bush is tight and full of crap, and when you move thats ure squeak

 

[smaddock]

I'd probably be more inclined to say its a "moan", and it doesn't go for a split second like you'd expect a suspension bush to do. When going around a corner it will "moan" for the whole corner sometimes, sometimes cutout half way thru, other times it will vary in pitch while cornering.

I really have no idea... its a strange one.

Ease of the accelerator when negotiating those tempting corners.
