i have a 93 with 6.5" lift and from day one has ripped up every pair of upper shock bushings. i've tried the normal of tightening down till they balloon out tell a little smaller than the washer .to being a little loose to a little bit tighter.it's like the washer is eating right throug the bushing or the other way around in some cases where the bushing is actually getting pulled down through the hole towards the wheel well.this is onlty happening with the upper bushing the one inside the engine compartment,not the one inside the wheel well.any links on some heavy duty bushings?
