Z4NZ 6 Report post Posted September 29, 2020 Hi Guys, My Z4 E85 got clunking noise coming from the driveshaft when going into reverse or drive. No noise while driving. Only when change the gear to R or D. Taken to BM workshop.They quoted for used or new driveshaft assembly, donut and hanger which is quite expensive. Is the driveshaft repairable or rebuildable? Can you please recommend a good solution? Thanks in advance! Quote Share this post Link to post Share on other sites

Z4NZ 6 Report post Posted October 9, 2020 Took it to Mint Motors besides Russel’s driveshaft rebuild shop. They said driveshaft seems fine. The clunking/ rattling sound is coming from diff? Any suggestion who repairs differential? 2 Quote Share this post Link to post Share on other sites

NZ00Z3 187 Report post Posted October 9, 2020 The clunk is common on Z3's and has been pin pointed to be the crush tube on the pinion. Properly the same issue on the Z4 diff. Here is a link on the Z3 diff. https://zroadster.org/threads/refreshed-rear-suspension-update.41075/#post-622137 Quote Share this post Link to post Share on other sites
