Are they in the middle where the two halves join? Link to comment Share on other sites More sharing options...
Bellato Donating Members 2,713 Member For: 14y 3m 20d Posted 23/08/12 01:11 AM Author Share Posted 23/08/12 01:11 AM Did a bit of experimenting yesterday on the way to uni! I put it over to manual, smashing my date and coming off. Tried to do it in different gears and at different revs. I found the lower gears (1 and 2) at about 3-4k then coming off boost was at its worst, any higher than this was fine and in lower revs was only slight (made sense because less boost etc). Tried to avoid wheel spin where possible so the shunt wasn't from the tyres hooking up.Also if I didn't just jump off the throttle and kind of eased off it a bit it was fine, only shunted when completely coming off acceleration.So this makes me think that it is more than likely my sh*tty rubber diff bushes Does this info help shed any more light on what it could be?

My car has done just on 20k, would the diff bush be gone already? Link to comment Share on other sites More sharing options...

Had my diff bushes checked and they were fine. The clunk got even worse once I got my ZF tuned, and at times would feel like I got rear-ended as I shifted into gear lol. I would look into the rubber donuts Pat mentioned, this is what I'm going to try, along with replacing most of my bushes with Superpro (more for handling reasons). If this doesn't work then I'm just putting it down to driveline backlash, which is what it feels like anyway. For now I've just learnt to live with it and try not to back off the accelerator quickly when it's about to shift into gear. I'll back off after it's shifted into gear.

Try using manual and coming off WOT in the same gear and see if you feel it. Makes me think moreso that it is the diff bushes or that rubber donut. I think I might be doing my diff bushes soonish just because I have 80,000kms and they have to be done at some point so see if that helps Link to comment Share on other sites More sharing options...

Bellato Donating Members 2,713 Member For: 14y 3m 20d Posted 23/08/12 09:41 AM Author Share Posted 23/08/12 09:41 AM Sweet thanks for that guys! Diff bushes will come at some point but good to know it won't do much here so I can put it off a bit. I have new shocks going in in 3 weeks so that 'may' help, but I don't think so.Like you said I'll just learn to drive around it Link to comment Share on other sites More sharing options...
