comanchePOWER Posted April 19, 2012 Share Posted April 19, 2012 just ripped out my d35, first rear end job ever for me, and so far its going well! the only thing I'm not to thrilled about was i had to cut my ebrake. it was jimmy rigged already, and poorly done, but i digress. i ended up getting chryco 8.25 out of a 97 cherokee which should be here tomorrow morning and thats when the fun starts! any helpfull info we didnt go over yet u think i should know aside from the perch welding Link to comment Share on other sites More sharing options...
Pete M Posted April 20, 2012 Share Posted April 20, 2012 is the 8.25 pinion the same length as the dana 35? my brain is telling me it's an inch longer. Link to comment Share on other sites More sharing options...
cruiser54 Posted April 20, 2012 Share Posted April 20, 2012 is the 8.25 pinion the same length as the dana 35? my brain is telling me it's an inch longer. Somewhere around there. Link to comment Share on other sites More sharing options...
comanchePOWER Posted April 20, 2012 Author Share Posted April 20, 2012 what would i need to do to make this drop in or should i get a different rear end. i technically havent bought the 8.25 yet but was literally about to Link to comment Share on other sites More sharing options...
Geonovast Posted April 20, 2012 Share Posted April 20, 2012 Get the 8.25, but you'll most likely need your rear driveshaft shortened. Very worth it, however, since the 8.25 you're getting is a 29 spline. edit: That's what I meant Link to comment Share on other sites More sharing options...
comanchePOWER Posted April 20, 2012 Author Share Posted April 20, 2012 how much u think some driveshaft work would be? and do transmission shop do that? I'm on a limited budget and would love to get on the road this weekend and to work on monday Link to comment Share on other sites More sharing options...
Geonovast Posted April 20, 2012 Share Posted April 20, 2012 When I had mine done, it was $102 for a cut, balance, paint, and new u-joints put in. I've heard of prices as low as $60. Link to comment Share on other sites More sharing options...
comanchePOWER Posted April 20, 2012 Author Share Posted April 20, 2012 ok i just answered my own questions via some investigative research sorry to have "freaked out" i found a very reputable place in south windsor ct and is called advanced driveshaft services and have read nothing but glorious reviews about them ill be going by later today to verify Link to comment Share on other sites More sharing options...

Pete M Posted April 20, 2012 Share Posted April 20, 2012 any plans for lifting the truck? Link to comment Share on other sites More sharing options...
Incommando Posted April 20, 2012 Share Posted April 20, 2012 If the truck is lifted you may not need any driveshaft mods. If your donor is a '97 it should have the stronger 29 spline axle shafts Link to comment Share on other sites More sharing options...
SW86 Posted April 20, 2012 Share Posted April 20, 2012 i didnt need to mod my driveshaft after the swap but i went spring over in the rear. i have no clue about staying spring under if thats what your doing also. measure twice, weld once! that includes axle positioning and angles Link to comment Share on other sites More sharing options...
comanchePOWER Posted April 20, 2012 Author Share Posted April 20, 2012 by the way I'm only 2wd!!! and hesitent to go soa but may do it anyway dunno yet i just got my chryco 8.25 and started pb blasting it, every part of the brakes are fuct! rusted solid any cheap solutions or any body know what a disc brake changeover would entail? a bit more work than i hoped for and the jy i went to wouldnt sell one to me with the brakes on based on a liability issue...scumbags ive also noticed i can't swap over the brakes off the d35 that wouldve been too kool thanks in advance Link to comment Share on other sites More sharing options...
Motion Offroad Posted April 20, 2012 Share Posted April 20, 2012 ...however, since the 8.25 you're getting is a 27 spline. If it's a '97 it'll have the 29 spline shafts. Link to comment Share on other sites More sharing options...

comanchePOWER Posted April 20, 2012 Author Share Posted April 20, 2012 so I'm still sizing this situation up and i think i am going to go soabut if i do will the shock mounts on the 8.25 hook up with the stock commanche shocks? they look close but not sure how to tell untill its in there Link to comment Share on other sites More sharing options...
comanchePOWER Posted April 20, 2012 Author Share Posted April 20, 2012 p.s. the chryco i got was from a 99 not a 97 Link to comment Share on other sites More sharing options...
Pete M Posted April 20, 2012 Share Posted April 20, 2012 are you prepared to pay for a 5-6" lift for the front? SOA is a lot of lift and has a ton of costs that go with it (bigger tires, gears for those bigger tires, lift for the front, shocks, brake lines, etc) and don't forget that you have to move the perches anyway. XJ perches are in a different location. Link to comment Share on other sites More sharing options...
comanchePOWER Posted April 21, 2012 Author Share Posted April 21, 2012 not prepared what so ever...for any of that. it would be too much stress on the front end to raise just the back that much huh? and i totally forgot i had to move the perches over anyway if i went soa. i apologize for this ignorance :doh: Link to comment Share on other sites More sharing options...
Pete M Posted April 21, 2012 Share Posted April 21, 2012 keep it simple. :D what's the gear ratio in the new axle? same as old? Link to comment Share on other sites More sharing options...

XJ perches are in a different location. Not sure If this will help you out but It will give you a Idea of how it will sit. on my comanche the previous owner put a 4.5 inch lift and then went SOA in the back. This was a 2wd truck and he had also converted it to a 4wd. From what I can tell the front axle and back axle are stock sizes but out of a xj. any way Here is some pictires of the back axle after the soa with the 4.5 inch leafs and how the truck sits.

comanchePOWER Posted April 21, 2012 Author Share Posted April 21, 2012 the gear ratio going in is a 3.55 it had a ratio of 3.07 (keep in mind I'm 2wd) also thanx for the pics gives me a good idea about what the soa would be like, very helpfull Link to comment Share on other sites More sharing options...
Pete M Posted April 21, 2012 Share Posted April 21, 2012 just wanted to make sure you weren't going backwards in ratio :thumbsup: 3.55 should make the truck feel faster :D I did the same thing back when my 88 was 2wd and loved it. Link to comment Share on other sites More sharing options...
