How to Repair the Headrest on a Jaguar XK8 / XKR
Here's a new, improved video of the headrest repair! Many XK8s and XKRs suffer from a problem where the headrests get stuck and don't move. The cause is a drive cable that has a jacket that is slightly too long. The solution is to open up the seat, cut the jacket on the drive cable, shorten it slightly, and repair it with shrink wrap. This video shows how to do it.
All it takes is a T-25 Torx wrench, a thin screwdriver, a razor blade or sharp knife, some heavy duty, thick-walled, adhesive shrink wrap, and a heat gun. If you don't have a heat gun, a propane torch will work, just be careful not to leave the flame in one spot for too long. Total time for the repair is probably less than an hour per seat. Having done it several times now, I can probably do both seats in under an hour. But if you're doing it for the first time, you should probably set aside at least an hour per seat.
