After installing my tires I noticed that the right side of my XJ is 1" lower than the left. What could be causing this? I changed nothing but the tires and rims

 

mine did this, and it was both the shock and springs.

 

weak springs, bad shocks, do you have anything that weighs alot in it?

 

No but I guess it could be weak springs. I'm going to lift it so I guess we shall see if that fixes it.

 

Mine was like that also, after I replaced the springs and shocks she was right again.

 

Had you measured it before the tire change? Most of us end up leaning that way, as the acceleration of the Jeep always torques the vehicle toward the right - it eventually wears the right rear out a little faster than the other side. Good times.

But also, check the weight distribution of the stuff inside, and the seating of the coil springs.

 

Its only the right front that sags. The right rear does alittle but im sure thats from the front sagging so much.

 

coils don't usually sag.
it's probably a rear leaf pack.
mine did this and boggled me big time till i removed both rear leaf packs to compare them to each other. one side was sagged.
(RE) replaced under warranty.

 

its prolly your springs dont worry about it since your gonna lift it anyways

 

Swap the springs side to side. For some reason it levels it out. Then Replace everything with a lift when you are ready.
