I haven't had the time to lube all the tracks yet as I want to purchase the best lubrication for it so hopefully it will last longer. What a pain in the rear end. Taking off the door panel is always a PITA but trying to take those ends off of the nylon thingie was the hard part. Once I got them off, installing them back was kind of easy. Only thing is my window is a little off track as it rolls up quite a bit slower. Any ideas besides additional lubing of the tracks which I haven't had a chance to do yet. I want to purchase the best and longest lasting grease to put in there so I never have to worry about the window regulators again. I have a 92 NSX by the way. Any suggestions? Thanks.
