Hey guys, Been lurking for a while and decided to sign up since I am looking to mod my 04 Xterra. The truck needs an alignment as is and have been reading up on the PML and figured I might as well do it before I bring it in the shop. So I went out and measured my bump stop clearance and its already between 1/2" - 3/4". I am talking about the top of the rubber stop to the upper control arm. Is this the correct way to measure it or is it from the base of the bump stop to the UCA? I went to the rear and the rear shackles look stock and do not see any add a leafs, just the overload springs. Appreciate the help.
