my truck leans down on the passenger side in the frontabout 1.5 inches lower on the frontpassenger side, does this sound like a shock or a spring problem. thanks

 

most likely your shock climb under and as long as your coil looks like it is still solid and strong its gonna be a shock.

 

i'm guessing it's your spring because your shock does not support the weight of the vehicle, unless the shock is putting your suspension into a bind...which i doubt.Anyways springs are known to sag. but usually it's the driver side. Superlift has a 3/4 inch spacer that you can get from them that should level it out.

 

on that subject...how often should springs be replaced?
