Mike, your solution seems like it would be best by far. However, I'm not an engineer and it's been along time since I stayed at a Holiday Express. If you ever do finish it, make soem extra parts and I'll buy some from you. I ahve discussed this with Ross and hoped he could come up with something better. I even sent him a link to you solution.
Tim,
I really do neeed to post a pic to show what is happening. My CV's don't move on the shaft either. The shaft and the CV's slide pulling the opposite CV out of the housing. The CV is still on the shaft. The axel deforms the end cap or goes thru the end cap. This extra movement allows enough movement to pull the other CV out of the housing just enough to slip. Let off power in it pops back into place. Hard to imagine but I have had it happen enough times over the years to be very familer with it. I'll post a pic later. Mark
