91' DLX 4x4 Pickup 5" Lift Kit 33" ProComp.....Detroit Locker in rear axle and street driving...... :-/ Now dealing with a very LOUD noise coming from underneath axle drive shaft and maybe transmission area of truck. Now I have have 94' Rear Axle Assembly and the noise remains much less frequently primarily when decelerating neutral or in gear.

Has anyone with similar modifications experienced this problem?

STRESS ANGLES caused by the 5" Lift Kit and 33" tires are suspect
