Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I'm not breaking the plastic ball ends but after a few up and downs, usually the passenger side adjustable arm "self adjusts". I have cranked those securing bolts down but they aren't very big. I do not want to strip the threads. I could put a helper bolt in the slot but I'm wondering if something is binding. However, I have had the top assembly off and it all moves freely. It closes and latches fine but after the arm slips, the clamshell won't lay flush. Any adjustment tips are welcome.

If you look closely at the connection, you can see grooves. This supports the strength of the connection through positive locking. Possibly (and I assume this) the grooves are worn out due to the constant movement. Tightening it more firmly will do little good, probably replace it with a new one or one that is good used. Or try an additional bolt, degrease beforehand. The weakest part is the ball socket (plastic), so don't worry.
