Well, I almost hate to say it but it was the other way around with me. The PO is a friend and co-worker, but not mechanically inclined at all. He was thinking that the truck needed a lot of expensive stuff, and really down-sold it. I'm having fun teasing him about how easy to fix some of the stuff that scared him was.
Broken seat mount- fixed with a hardened steel washer in a half hour.
Dead AC: $76 for a compressor shaft seal, $25 in R-134a, and a few hours of my time to R&R the compressor, take it to the rebuilder shop, and then evac/charge the system.
The radiator did have to be replaced, and the coolant looked like the inside of a used baby diaper so that was worse than I expected. Flushed really good, and its staying clean now.
After that discovery, EVERY fluid got changed. None were as bad as the coolant, but they were all due.
Annoying creak in the front suspension when backing up and turning- figured out it was nothing serious (slightly worn bushing) and turned up the radio
He did say he thought the tires "had a lot of life." Well, they were dry-rotted pretty bad and were UNDER-sized at that! Who puts P215 70R15 tires on a Jeep?!?
