I just put a new lift (4" LCA) on the TJ and noticed the front passenger spring is a bit funky.
Supposedly both springs are identical although I haven't swapped them around yet.
The problem I have noticed is that the passenger side spring seems to side too far to the rear (has a slight bow in the middle) and as a result the top bump stop rubs a little as the spring compresses. The spring is sitting in the little notch on the bottom perch so it's orientated correctly. About the only thing I can figure is that the little spring rentention tab + screw wasn't on the jeep when I got it, and therefore is not installed at the moment, or the spring has a slight warp to it.
Ideas?
