Exclamation 99 Boxster Roof Off Tracks! Need help

I'm new to the Boxster community and my fears of reliability came true this weekend when raising the convertible top. It appears the attachment bolt from the passenger side black actuator came out mid-operation (pic5) and somehow the ball socket on the driver side of the clamshell/ tonneau cover popped off the track(pic 3,4)?! Not sure the exact order of events, but after searching forums and youtube, I am unsure of how to proceed.

The top will still raise and lower evenly. Both lower connecting arms with plastic endpoints are intact (pic7). The threads seem to be intact where the passenger side hydraulic arm bolt attaches to the transmission assembly (I was able to get them to catch and left it hand tight for now- pic5,6).

If you have experience with these tops please advise and thank you!

I have things moving in the right direction or so I hope! I removed the clamshell which allowed me to pop back in the ball on the driver side where it belongs on the sliding track. With the top in maintenance position I reattached the bolt end of the black hydraulic arm on the passenger side with 17mm open ended wrench. Ops checked good.

When I went to replace the clamshell it was twisted, so I have to work on getting that sorted. Hopefully if that goes well everything will operate smoothly.

Good luck! The mechanism back there isn't super complicated and, as you've found, it's pretty easy to figure out how everything works. While you're in there make sure you check all the mechanism connection points and try to figure out why it got loose in the first place. Torque up the bolts, lube the friction points, check the foam rain liner for any tears/holes, and make sure the drains are clear of debris.

My top came loose a few months ago, and when it did, it drove a metallic arm right through the foam liner...

to pop back in the ball on the driver side where it belongs on the sliding track

Consider replacing the top guide arm slide, and the bearing sleevs, 999-924-130-40

and the sfety clips 999-166-077-02

These are dirt cheap and woth the time.

Personal experience.

Thanks for the replies! Yes, so far I have been impressed with how easy the Boxster is to work on. Good idea to replace those cheap plastic bits and hopefully avoid this from happening again. I have no idea why the passenger arm bolt would have loosened completely from the transmission assembly while the driver side is still torqued snugly.

Before asking a friend to come over and help straighten out the clamshell I took another look at things. I may need to make some adjustments.

Pics 8 & 9 show the clamshell attachment arms when the top is in nearly stowed position. The drivers side is about 1-2 inch higher than passenger side. Pic 10 shows the arms when the top is opened more.

Pics 11 & 12 show the top when it is near its service position. The arm on the driver side starts to dig into the weather stripping.

I've read up on the disconnecting the cables from the motor assembly and I assume that is what my next step should be? If so, can someone please clarify what side cable I should remove and what direction I should operate the top? I would go by trial and error, but I'm afraid of making things worse. When almost closed, the top looks to hitting the header roughly even. I wouldn't have noticed things were off if I was looking only at the top. Thank you!
