know the V8 ZJ pitman arms will give you around a inch drop, why do you need so much? I have the rusty's 1 1/4 in drop on my xj with around 6 inchs lift and its fine, no bumb steer
at the botom of the piman arm the tie rod that conects the steering has a boot with a greese fitting. my old one the boot broke and i have put 5 on the last being a moeg and the boot keeps seperating at the base and the greese comes out. i was thinking jthat maybe the angle was afecting the seel
I know i have ruined one by putting too much greese in one. i'd say with only 3 inches of lift you would be fine by running a ZJ pittman arm, and it be on the cheap
Skip the crappy OE rubber boots that come with new joints... a 2-pack of poly boots are cheaper & will last MUCH longer. Coupled with your maintenance, you should get some decent longevity...
