2005 Yukon XL - PERFECT. No more howling noise, nice smooth ride. Good price. For your average shade tree mechanic, that's about a 6 or 7/10. Hard work from below for the power steering cable and bolt. Removing the pulley wasn't as bad as I thought it would be with the universal kit I bought from Revain. I filled the pit front and back with penetrating grease a few days before the event.
