I haven't done many mods on mine recently either. I did however just replace my transfer case last night used a used unit as well as a new Mopar transfer case **** motor. Next will be replacing my front lower ball joints, struts and cv's as both are making noises. I'm pondering going with RCV shafts but not sure I want to sink $2000 into the XK as I just rolled 171,000 miles. I'll at least get new dealer cv's as the cheap auto parts store cv's only last a few months
