a noise has developed at the rear of my 2wd cossie,it just happened after overtaking on boost on the way home just there,its a kind of a humming sort of a noise,hard to describe it,but its only there on no throttle,when i accelerate or maintain a speed it dissappears,but when i ease off its there.any ideas what it might be before i go stripping the back end during the week?
any ideas appreciated,cheers.

Hmmmm does sound like the diff mate. take the rear seat squab out (only takes a jiffy), fold a seat down and listen again - should be easier to determin if it is the diff cos its just under there and the noise will transmit more.

This was how I tested mine with that noise - then after a run and a clunk it got a lot noisier and had to change it.

 

lovely,wouldnt mind but the diff never saw any abuse or hard launching!cheers

 

Have you lifted the wheels and checked the rear bearings??? Hows it going mate?

 

yeah i personally would point towards diff or diff bearings or wheel bearings

 

no i didnt check the wheel bearings,didnt think it would be them thou cos the noise is only there when the car is decelerating,thats why i thought its prob a diff bearing thats gone.ill check em this eve thou before i take the diff out just to make sure.

 

Ive got this noise on my 3 door, needs new rear wheels bearings and a diff rebuild
