Hello all, we installed lift onto my sons 2015 Z71 height and lift manufacture I don't believe relevant here. clunking noise started also, when he took to dealer they told him they did the recall thing that didn't fix anything, then the steering went out all together, we decided to remove rack and pinion and disassemble we found the belt for the electric motor had broken. The PN on the belt is 28271802. We cannot find this belt unless you order 100 from china! As someone here has all ready said I think we'll buy a new rack and pinion and sell this hoopty.
