Driveshaft investigations

For the first time since it's MOT a few months ago I've been spending some time on the GT6 (SS Freshspring has been keeping me pretty busy recently) First off was a clean and wax, which it hadn't had for far too long, then it was onto a bit of investigations.




One of the reasons that I have not used the GT6 much was due to a noise from the rear I could not identify at the time. Initial investigations showed some slack in the inner CV joints, so a replacement pair have been sourced and this weekend I got the back end up in the air to remind myself what was involved in the task. As the weight came off the back end I could hear that previously unknown noise coming from the rear transverse spring, ah, that'll be cause of the noise then. I could just spray a mass of oil at it, but seeing as it would not last and I need to disconnect the spring to remove the driveshafts, I may as well pull the spring all of the way out, service it and cover with denso tape to prevent a repeat of the problem.
The reason for doing this investigatory work is that the last time I had to dismantle the rear hubs the trunnions were seized, creating much more work and bush replacement. Fortunately they proved not to be seized this time, proving that the anti-seize compound I used last time has worked.

Next step is to strip it all the way down, find the right lubricant for the spring and source some denso tape.
