my x have 17000 miles and yesterday i saw that the pasanger side has drop´in the frot 1.5inch and in the back 1inch what i need to do?????

I'm not completely sure I understand what your asking, but if I've deciphered it correctly one side of your X is lower than the other?

If that's the case, crank the T-Bar on the lower side until they are even, drive a couple of miles, re-adjust and repeat until you are even, then get an alignment.

Instructions to crank T-Bars are here: http://www.maxc.org/mods/torsionbarHOWTO.htm

Do you have alot of weight on one side?

i'm going to adjust the t bars

and the x is whitout load

Get an alignment done after adjusting the t-bars.
