I received my set of Lube Groove bushings earlier this week for the FD. They are made of Delrin® and have a internal groove machined into them for some PTFE grease which will greatly reduce any bushing noise and increase the life of the bushings. Delrin® bushings are stiffer than polyurethane bushings and offer a longer life. The 18pc. kit came with all these bushings:

-4 front upper control arm bushings
-4 front lower control arm bushings
-4 rear upper control arm bushings
-2 rear upper control arm shock mount bushings
-2 rear trailing arm bushings
-2 differential mount bushings
I am also replacing all (6) of the pillow ball bushings while I have everything torn apart. Hopefully I will have all of this done by next weekend.
