Filling then with grease is a no no for teflon lined bearings. The grease can destroy the Teflon lining. Also, any dust or dirt that gets in will cling to the grease and potentially wear out the joint. As a thought, 50% of the rear is spherical, especially the PP1 cars. One end of the tow link. One LCA joints, and one in the knuckle. The one difference is they have a nice factory seal. Not sure if they are teflon lined.
I used them on the toe links and LCA bearings. Not a 100% seal but better than nothing.
Agreed. None of it is really necessary for street driven cars. In my case, I came across mine from a buddy that owns a local speed shop and had them as a non picked up order so I got them dirt cheap. In my case I probably didnt have to do any of what I did, but having an engineering back ground, when I found out what was in there (you were instrumental in alot of that), I felt compelled to "upgrade". Its overkill in my case. I even changed the axles. I figured since I was in there. And if I ever decide to track it, its ready to go. In hind sight, if I ever bought verticals again, I would have done the delrins. The hardest part of the job (LCA, toe link bearing, toe links, vertical links, axles) was screwing with the shocks to get enough CV boot clearance to the shocks. And my quick jack screwed up, and not realizing how stiff the magnaride shocks are when trying to preload suspension. We thought we screwed something up because the suspension wasnt moving much...until we undid the shock! The suspension moves more when you load it from the outboard (dah, longer lever).
Sooooo boring
I have a hard time leaving things alone if theres a chance I can make it better. I had the car out for longer ride today and hit some crappy roads. If its stiffer, it's not by much, but it feels much more planted. And its quiet. Rear jounces is about as much as the front which is not much. Overall, I'm very happy with the mods
