2001 GMLS, 130K, installed 2 sets of links in 12 months and it sounds like one side is going bad again. I drive slower than my dad the original owner. The air suspension removed and springs in back...kinda rides high in rear....any pressure pushing the front off balance. Bought links from Autozone both times. Suggestions? Also, have that ugly metal crunch noise when turning left making daily uturn into my apartment. Thanks for any help.
