I have another problem, ok i've had the gearbox fixed all running ok, i've put a new (2nd hand) diff in. I get a booming/droning sound from the rear. I've had the car running on a ramp in 1st gear.

The g/b and diff run silent, the wheel bearing have been check and ok, is it possible that the boomingnoise from 30-70mph could be tyres ? the tyres on at the moment are 245's not the recommended Bridgestone 225/50's. I don't want to change the tyres over and get the same sound but has anyone ever had a noise with different tyres ?

Could the rear geometry be out ?

Thanks.

 

I do not know what the sound you are describing, sounds like. Could you possible take a sound or video clip for us?

 

I'll try I haventgot the car back yet, it's like an echo/drone sound comming from the rear.

 

That could be your tires... Best way to rule that out is to swap in another set of wheels. The diff is also known to make that sound = not good.

 

I'm thinking tyres, I've already swapped out diff and had it running on a ramp and it was quiet. I think it's tyres/rear geo a mate has got 17" wheels on his S2k so I might swap them over to see if it's that... Then buy new boots if it makes a difference.
Thx

 

Give that a shot and report back. Wouldn't hurt to get an alignment as well (with your wheels one).
