Just got my 2010 white sport crew 4x4. Stopped by 4wheel parts in Houston to get a leveling kit installed. All the kits were basically the same 2.5" lift. 4Wheel parts guy told me they had a disclaimer in their system that all the 2010 and 2009s that have had leveling kits installed are seeing premature ball joint wear. Most within 10k miles needed to be replaced. He suggested I wait 6 month a check back and see if any of the manufacutrers have addressed the issue. Anyone here have a kit that works or can anyone confirm what I was told?
