Chrysler 8.25 swap
I'm considering swapping to the 8.25, just looking for some input from others who have done it. What I'm wondering is if I could leave the spring perches over axle and get some lift out of it while I'm swapping them.

All 8.25" axles are already SOA.

No additional lift by installing an 8.25" axle. It's already set up the same way your D35 is.

parking brake cable is different from the D35 in my 89 to the 8.25 that I installed. The cable is the same I guess, but the end is different, so I have to replace the cable to get the correct ends to have a parking break again. Took me about an hour and a half to do the work entirely by myself.

Yes. But I'm wondering if I'd be able to leave the perches over and be able to mount everything up.

i know of a couple MJ buddies out there that have just made the leaf springs fit to the oppposite application (MJ leaf setup to stock XJ perch's AND ive seen XJ setup to MJ perchs). Not really hearing any big complaints but i will tell you after doing it recently with a junk MJ rear axle to roll an XJ outta my hair... the leaf spring bushings do not look like they would like to be that way for a long period of time. I don't think i'd do it for a DD, but a trail jeep that your trying to be really cheap on? Go with what you feel.
|
FWIW I just worked on a 92 MJ and the guy had an 8.25 and he left the XJ perches. Has wheeled it for 3 years like that. Not sure how he got the pins but I imagine it wasn't all that hard

Either do it right or don't do it at all. Members safety is not worth cutting corners. Weld the right perches where they belong. If you can't do the work or are too "cheap" to have someone do it, you're better off staying with your stock axle. In anything automotive, if you want quality upgrades, its going to cost or you have to be good at fabrication yourself. Drivetrains is one of those things you don't want to be cheap on.

I the mj i bought came with bent up leafs because po didnt realize the perch setup wasnt the same as an xj. But i fixed with a 8.8.

I "just" came home from pulling a rear axle from a '94 Comanche 2wd/auto (local add).
Wanted to get other parts for my 88 since they aren't a common truck here. Crawled under and !!! Dana44 !!! (3.54/LSD tags still on.. But a funky looking drive shaft..?) I'll take some measurements tomorrow and hopefully pics. (for some reason Imageshack makes them HUGE) I have a'97 Cherokee 29 spline 8.25. A 2wd 8.25 that's in my 96 2wd but it's a 27 spline. A MJ axle that I looked in the door and it is a '94, with the spring UNDER axle. Then my '88 comanche which is a Dana 35, spring UNDER axle. I will measure also the 44 along with the others just to see for myself if there are any differences, Again, since I've only read of the infamous Comanche Dana44. Also for reference, I also have my son's '01 Cherokee with 8.25, 3.55's (4wd) Errol |
They stopped making Comanches in 1992

8.8 !!! Weld perches ! Once u get the perfect ride height! 8.25 is a good axle tho! The 29 spline!
|
when i got my mj the guy had already put a 8.25 under it. i put another 8.25 and i have to cut and reweld the spring tabs ill post pictures when i do.
