My rear lower spring perches have the nut and bolt exposed. It has a retainer plate that holds the lower spring in place. The bolt tears up my bump stop when it contacts. Something I’ve noticed, every other TJ rear lower spring perch I’ve seen has the raised pad to contact the upper bump stop. Am I missing something or is this how some rear axles came from factory. FWIW, it’s a Dana 44 that came from a TJ sport.
