2003 TJ 5spd, 4" suspension lift with 33x12.5 all terrain tires. Here is my issue: I had the clutch replaced by a shop 10,000miles ago (forget which brand clutch, sorry), and it started slipping a week ago. I immediately brought it back to the shop and he took it in and just called me today. He said he replaced it and it looked like the rear engine seal leaked oil (these always leak, but mine isnt noticeable other than a few drops here and there) onto the clutch causing it to go bad so quickly, or the gear ratio (D44 3.73) wasnt adequate for the 33" tires. I want to call BS on him, but he isnt charging me for anything, which leads me to think he messed up in the first place. I just wanted some opinions on if either of these "causes" should be addressed to prevent it from happening in the future. any help is appreciated.
