My YJ Project

I have been driving/wheeling a Jeep XJ for a few years now and have been happy with it. It now needs too much work to continue and I got a great deal on a built YJ, so time for a switch.

The YJ has a full size Chevy drivetrain.
  1. Carborated Chevy 350
  2. 4 speed manual tranny (1st gear granny gear)
  3. Chevy tansfer case, not sure which one yet
  4. GM 10 Bolt axles front and rear (8.5 ring gear, not the S-10 axles)
  5. A few other custom stuff

Motor has a bad lower end knock. Either a bent piston rod or spun bearing. The guy told me the oil was over filled by 3 1/2 quarts when he bought it. When I drained the oil, there was less than 2 quarts in it, ugh.

I spent hours and hours surfing NAXJA when I first started wheeling my XJ. Now I want to learn as much as I can about my new YJ and the GM drivetrain. Any comments, info or direction would be much appreciated.

Hope to have many long, family fun filled years with my new rig.

welcome, and it sounds like you have a lot of work to do. off the top of my head your trans is probably a 465, transfer case could be anything. I'm not a big fan of the 10 bolt. I put in one ton axles in a blazer last year for a friend. but in a jeep they should be OK. are you running full width? the upside to running chevy is its cheap and easy to find.

sounds like a heck of a project! Nothing like a Chevy powered Jeep!

Post some pics, and be sure to rip into that 350 or replace it soon. Don't run her into the ground with that knock, the longer you wait, the more internal damage it will do.

Thumbs up

Thanks for the replies. The axles are full width. I'm not driving the Jeep right now. I am going to take my time tinkering with it and fixing all the little problems with it first. BTW I got this gem for $500!
