i have a 1992 XJ with the NP231 and i lifted her 3 inches using Rusty's lift and added the 1 inch drop crossmember at the same time. i noticed a vibration right away. my mechanic took a temp gun to the u joints at the rear and said they were fine but i wasnt convinced. i took it to a 4 wheel drive shop and he looked at my driveshaft and said the angles were fine and he thought i needed new control arms to align the font end properly. i put the lift on at christmas time and i havent gone through any u joints... any ideas?? not sure what the angles on the drive shaft are or the caster....maybe if i took off the one inch drop?? thanks for your help!
