There is nothing worse than enjoying a day in your 911 with the top down and having to listen to the sound of a loose Tonneau cover flapping around and maybe doing damage to your paint. The cover is just held in place by a series of Tenax fasteners and it is quick and easy to replace the broken ones.

This article will show you how to replace both the caps and studs.

The Tenax fasteners (yellow arrows) that hold the Tonneau cover in place are not cheap to replace when they break but they are also not difficult to replace.

Pull the cap (green arrow) up from the stud (yellow arrow).

Pull the cap (green arrow) up from the stud (yellow arrow).

As the caps age the small clips inside (yellow arrow) will begin to fail and eventually leave the cap loose and the cover flapping around in the wind.
Figure 3

As the caps age the small clips inside (yellow arrow) will begin to fail and eventually leave the cap loose and the cover flapping around in the wind. You can see how the new cap has much more grabbing power (red arrow).

To remove the old cap use a set of circlip pliers and insert them into the two openings on the back of the cap (red arrow).
Figure 4

To remove the old cap use a set of circlip pliers and insert them into the two openings on the back of the cap (red arrow). Turn the backing cover counter clockwise and unscrew the backing plate.

Remove the backing plate (yellow arrow) and push the old cap out from the cover (red arrow).
Figure 5

Remove the backing plate (yellow arrow) and push the old cap out from the cover (red arrow). Check the top for damage and clean any dirt or debris.

Insert the new cap and backing plate and using your circlip pliers screw the backing plate to the cap until it is firmly set (red arrow).
Figure 6

Insert the new cap and backing plate and using your circlip pliers screw the backing plate to the cap until it is firmly set (red arrow).

To remove the stud use a 9mm wrench and unscrew it form the body (yellow arrow).
Figure 7

To remove the stud use a 9mm wrench and unscrew it form the body (yellow arrow).

The stud (red arrow) is just a self-tapping screw.
Figure 8

The stud (red arrow) is just a self-tapping screw. The top under the Tonneau cover is glued to the body and the stud screws through the top and into the body (yellow arrow). Screw the stud down but do not over tighten or you risk damaging the stud along with the hole in the body.
