Earlier this year I bottomed out on a major evil pothole from hell. Left rear wheel.
This has lead to an ongoing problem where the back left lower shock bolt starts to come slightly loose and will need to be re-tightened.
Indicators are a metal on metal sound that gets louder and louder and a slight looseness in the back.
I've had it checked by local guy and a VW pro shop, and neither could find anything wrong. The only thing the pro shop pointed out was that my spring seats in the rear are extremely thin (Mfg Part # 1K0512149B) and that getting normal sized ones might alleviate the problem. Even talking it over with my local guy, who found the loose bolt to be the only answer, isn't sure if that'll solve it perm or not.
The thing is, once it's tightened, there's no noise, even on big bumps, no give in the back nothing, and the build up is slow and gradual.
This problem did NOT exist at all previous to hitting that pothole.
So wondering if anyone has experienced anything like this and what the answer was for you?
