I know your joking but, oem joints aren't greasable
Although and because I assisted on wrockwraiths joints at the wrenching party I'm letting the dealer do mine. If its just the joints it will be covered by my partners warranty. Ironically I chose a small lift and tires on stock rims to avoid this sort of thing. Seems there really is some design flaws. Never had these issues on my cherokees or j10 and they got used a little too.......in fact the j10 could carry some HEAVY loads and did so for a quarter million miles on original ball joints. I'd lay blame on the discoing but rubicons have the same problem and were "designed" to disco...
anyway, its at the dealer now (cue jaws music) dumb dumb, dumb dumb
