Ok, I've searched the archives and I don't see a ready answer to my problem... I noticed before I installed the 4" lift (truck previously had a 2 1/2" Rancho lift) That when making a sharp right turn, the left front corner(hub or stub?) seemed to make a couple little "pops". After installing the lift (I left the shims from the 2 1/2" kit under thenew leaf springs) the popping seems to have gone away??? In it's place is a "rumble" in the front left corner (I think) when coasting. The truck drives great, makes the tiniest vibration while accelerating up to about 20mph then goes away, makes no noise while accelerating, doesn't rattle or sound loose when going over bumps, I've shook that tire while in the air and there is no obvious bearing/ball joint slop... I know I need to install shims under the rear springs because they haven't been corrected for the lift and the rear driveline has a bit of angle on it, but the front angle looks good. Help???
