pitbull4x4 Posted October 22, 2011 Posted October 22, 2011 A guy is going to sell me a dana 30 front and dana 20 rear out of his late 80's wrangle for $50. Wrangle had a 2.5 GM motor in it. Are these going to be to small/long to fit under my 89 comanche? It is a 2wd, 2.5, 5-speed and want to do a 4wd swap. I know the spring mounts will have to be changed.
Pete M Posted October 22, 2011 Posted October 22, 2011 not without a lot of work. that era wrangler has leaf springs up front. (and only had the Dana 35 as a rear axle)
Incommando Posted October 22, 2011 Posted October 22, 2011 The Dana 20 is a transfer case. The AMC 20 is a rear axle that was only used in the CJ-era, never in a Wrangler. A CJ of that era would be a passenger drop low-pinion axle, not the most desirable.
pitbull4x4 Posted October 24, 2011 Author Posted October 24, 2011 Sorry about saying it was a dana 20. I did not know it was a t-case not a rear end. It sounds like I need to look into other axles. Thanks

Look for a 94 Cherokee donor........everything you need is there.......including the external slave bell housing. Will come with the 4.11 - 4.10 gears. Typically the 2 door variety.

Typically the 2 door variety. also you will need a shorter rear drive shaft, one from a cherokee will not fit. if you use the cherokee rear axle you will need to move the spring perches. make sure the crank position sensor an the bell-housing it in the same spot as the old one. 94 transfer case will have the electronic speed sending unit in it, just remove it and use your old cable setup. now would also be a good time to change your lower control arms to ones from a WJ. viewtopic.php?f=2&t=32508
Jeep Driver Posted October 24, 2011 Posted October 24, 2011 http://louisville.craigslist.org/cto/2637841695.html Or if you can get a hold of this guy.........lord knows I've tried............he has what you need. This ad does not state that the Comanche had a 2.5 but his previous ads did, he has sold the 2.5 from what I gather. I believe he will not respond to me because of and out of the area phone number........but he has stated that the trans is relatively new.
Pete M Posted October 24, 2011 Posted October 24, 2011 specifically a 2.5L XJ. any year MJ/XJ/TJ 4wd 2.5L/5spd will work. double check the gears before buying, but most were 4.10.

The drive shaft he will need to get made.
Jeep Driver Posted October 24, 2011 Posted October 24, 2011 http://greenville.craigslist.org/cto/2664736234.html This will work too. But I prefer the later axle and external slave.
