Clutch help

LUK is the way to go. I go to their Repset Catalog website, figure out the part number (05-065 for most if not all 4.0 TJs and YJs with the AX-15 and NV3550, but to be sure, check at LUK's Repset catalog website, if you have a 2.5 it'll be a different part number for sure which I don't know the number of off the top of my head), and then I take the part number to Amazon and buy it. The one I just mentioned is $87 bucks on Amazon right now. That's a heck of a deal for a clutch.

Pay no attention to the people griping in the reviews about the "plastic" (composite) throw out bearing, it still has metal where it needs it and the composite is non structural, mine has been kicking for 2 years and 20,000 miles with no problems.

That is the website where you look up the part number you need.
