    Get some sikaflex 252 in the bushes. Not had a sound from mine since. Or buy a mount from 034.

    You can get sikaflex 252 from most online hardware stores. Its just polyurethane in a tube. The performance mount/bush can be found on 034 motorsports website. Costly though and from the states.

    Checked the thudding noise it wasn't the bushes I'd some how with my lead foot managed to work the 3 8mm hex bolts at rear of diff loose which is a bonus bit aid loctite and it's gone :) !!

    Going to get the sikaflex I think just to prolong the bushes and cut some slack, can I basicly do every mount on the car with this stuff and how long does it take to go off roughly and do I have to remove the bushes or just lower them to get the sikaflex in ??

    you can fill both diff and both gearbox mounts, then get a poly front snub mount

    ideally you want to get some spare mounts as even the fast cure sika takes a few days to harden and the main diff mount needs doing in layers or middle will never set

    well worth doing though
