Kicking my nose tire directly from the front confirms this. I'll replace mi ne also. Second, if you look at the way I installed my plastic at the strut top it will stretch out the bungee more making more friction like Fritz said. The way you did it John, by atta ching the nylon to the top of the strut cap will not stretch it, which is a really good idea. The only possible dow nside is the nylon is rotating over the painted firewall instead of the metal cap rotating over the plastic could c ause friction. I found everything worked good till paint was applied and everything was stiffer. If you look near the top of my stru t it looks chrome. I had lots of binding with the thick grey paint around the bearing. I sanded that area to bare metal and put a v ery light coat of chrome paint and greased the heck out of it. This eliminated lots of friction. I also used the plastic at the V area and decreased but did not eliminate the V angles. This worked well to eliminate some friction. Go down to the 11th picture on to see. http://www.701builder.com/LandingGear10.htm Using UHMW instead of Nylon66 for these bearings has helped alot per the ad vice given by this 1998 message from the Zenith List. Originally I did everything in nylon. You can get it from US plastics or McMaster Carr.
