Hey y’all. I just discovered that many of suspension fasteners are TTY and should be replaced after loosening or removing. Since the MSS spring install I’m getting a slight dull pop/ clunk noise at slow speeds turning. I suspect it’s the top strut nut. I just purchased some new fasteners and want to replace and torque them to correct specs. I’ve been searching an unable to find f97 f98 torque specs for suspension components, anyone have them or suggestions on where to find the specs. TIA

MSS are notorious for these issues. Had mine installed and ran into noise on the passenger side when turning the wheel while reversing. To correct the issue I twisted the spring 1/4 until I didn't here the noise again. Also I'm not too happy with the ride quality. I will be switching over to the KW V3 after all the upcoming holiday (something I should had done from the start)

Interesting, so you spun the height adjusting collar a 1/4 turn? Isn’t the spring itself indexed into bottom and top mount so it’s unable to rotate? Thanks for the suggestion

Please keep us updated if this solves your clunking noise.

I'm experience a similar clunk when slowly reversing up my driveway with the steering wheel turned.

I think the correct term is BMW McPherson suspension top mount is notorious for this issue.
G2x and G8x are having issues even when stock.
Seems like BMW quality is getting worst and worst.
The early production X3M/X4M doesn't have issue as much as the later production one.

Wow! was not aware of this. Crazy how BMW make these car's with poor quality parts.

New X3MC muffler. Have pin hole leaks on the exaust. Pictures attached.

Rattling muffler chamber divider plates, rattling exhaust valves, missing or loose nuts/bolts/screws. Etc.
It just getting worst and worst.

What I noticed. First couple years, quality are better, except software glitches.
Then software glitches are fixed, but components are getting downgraded.
