You could also check the alignment to make sure the top isn't binding when it moves.

If it's coming from either of the transmissions then it's likely the gear.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • Planet-9: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

Hello all, Today when lowering the top on my 987.2 Boxster base , the top and clamshell were shuddering/popping. I only opened to top about halfway. I closed it up, and experienced the same shuddering/popping as it closed. I lowered it again about halfway so I could see the white plastic ball-joints on the arms (I had one of plastic balls break about six months ago and replaced it). The white ball joints both look okay. What else can I look at to figure out what's going on with my top. Thanks for the insights! Mike

POST 2Original post

The noise might be coming from the convertible top transmission. I had a similar issue and it turned out to be a cracked transmission gear. I replaced the white plastic gears in both transmissions, realigned the top and it works smoothly again. -RobT Sent from my Pixel 3 using Tapatalk

POST 3Original post

Thanks for the reply and images Rob. Is there any way to check for this without taking the transmission apart to look? Thanks again! Mike

POST 4Original post

You could try to locate the source of the noise. If it's coming from either of the transmissions then it's likely the gear. You could also check the alignment to make sure the top isn't binding when it moves. If you get any top not closed errors then it could be a switch or transmission problem.

POST 5Original post

Many thanks Rob! I'll see what I can diagnose around work this week. Mike

POST 6Original post

Update: It was indeed cracked plastic gears. The more I looked at DIY'ing, the more the job started to fall outside my comfort zone. The fine folks at Freed Performance got it taken care of for me. Thanks for the insights! Mike
