JeepcoMJ Posted August 22, 2007 Share Posted August 22, 2007 got a friend who's junking a 94 xj he and I picked up. it has a chryco 8.25 rear axle, dana 30 non-disco front with 3.55's and all associated hardware. when I compare the shafts where the ujoints go to the ones on the 3800 or the 89, I notice they're much heavier duty shafts...but is that the better ujoint as well then? sorry no pics. also, would this be the year to upgrade my booster from? I'm taking the prop valve for the 89, and I also got the aftermarket seats, and seat belts, will get the shackles, ebrake assembly, 3 piece grille (for a friend), tilt column (will need electrical mod to work with older style system) plus lock cylinders, all computers, cruise module, and a few other things I can't think of... all for $100 and I help him scrap it (chop nice rockers and rear pass quarter so we can replace the ones on his DD/wheeler). the PO thought it didn't run well so he scrapped all of the engine compartment stuff on the engine and general things associated with the engine...meaning intake, valve cover, all wheels and brackets, all wiring...you get the idea... Jake payed $160 for it after that. I think it has LSD too. 101,000 miles on the dot. Link to comment Share on other sites More sharing options...
offroader461 Posted August 22, 2007 Share Posted August 22, 2007 booster upgrade is 95 and up....94 still has single diaphram...not worth squat U-joints were changed over in 93/94 i believe...not 100% sure Link to comment Share on other sites More sharing options...
JeepcoMJ Posted August 22, 2007 Author Share Posted August 22, 2007 booster upgrade is 95 and up....94 still has single diaphram...not worth squat U-joints were changed over in 93/94 i believe...not 100% sure thanks! hmm...I think I'll still grab the booster anyways cause the one in the 3800 has a drill hole (repaired with a rivet and some calk...) in it. still gettin a good deal on the axles tho I think...they'd be a good upgrade to the 3800 as my front axle is bent, and my rear is a damn turdy-5...

offroader461 Posted August 22, 2007 Share Posted August 22, 2007 if the booster works...swap it in...no biggie The D30 would be a good swap...even just to use the shafts...That 8.25 i believe is a 27 spline unit which is only a little better than the 35 but still better...I'm swappin my D35 in the XJ to a 99 8.25 w/3.55 LSD and alloys i just got :D Link to comment Share on other sites More sharing options...

Rob S Posted August 22, 2007 Share Posted August 22, 2007 The dual diaphram booster started in 95. The upgraded axle started in 96 (usage of 297 joints). Link to comment Share on other sites More sharing options...
JeepcoMJ Posted August 22, 2007 Author Share Posted August 22, 2007 The dual diaphram booster started in 95. The upgraded axle started in 96 (usage of 297 joints). it had abs. therefore it's probably got 297 ujonts. Link to comment Share on other sites More sharing options...

JeepcoMJ Posted August 22, 2007 Author Share Posted August 22, 2007 anyone have a picture of it in the axle (so I can see the axleshafts?)? I've tried searching a few sites, and google, but no avail. Link to comment Share on other sites More sharing options...

offroader461 Posted August 22, 2007 Share Posted August 22, 2007 swapping the rod is a lot more complicated than it seems...i tried and failed...use the 96 booster w/the aluminum spacer and it lines up perfectly...i didnt have to cut grind or modify anything other than brake lines to get mine in...easy as pie :D Link to comment Share on other sites More sharing options...

I don't know exactly what is entailed, but you need the newer m/c and the older m/c out and cleaned up, then you take them both apart, swap the rod, and put the newer m/c rod into the older m/c and put the old one back in... or just put the new style m/c and booster in...

offroader461 Posted August 23, 2007 Share Posted August 23, 2007 swapping the rod is meant for the booster to the pedal...not the master cylinder...you need the correct m/c for the booster...the rod from the booster to the pedal is the problem...thats what they mean by swapping the rod Link to comment Share on other sites More sharing options...

DirtyComanche Posted August 23, 2007 Share Posted August 23, 2007 So, uh, which booster do I use? Do I need anything else? Mine is fuct. I want to just buy a new one. Link to comment Share on other sites More sharing options...
offroader461 Posted August 23, 2007 Share Posted August 23, 2007 if you wanna do the swap and make it easy...buy a 96 booster and click on pete page that he supplied and it really simple Link to comment Share on other sites More sharing options...
DirtyComanche Posted August 23, 2007 Share Posted August 23, 2007 Bah, I'd need to find a 96 XJ in the junkyard for the spacer. Not likely to happen. Link to comment Share on other sites More sharing options...
Rokhound Posted August 23, 2007 Share Posted August 23, 2007 get one of of ebay and ask if it has the spacer. That is what i did but i messed up and got a 99. So if you want I have the 99 with the spacer to. All you need to do is shortin the rod. I will sell it for what i paid for it which was like 20-25 plus shipping. Also in has the MC attached to it let me no Link to comment Share on other sites More sharing options...
DirtyComanche Posted August 23, 2007 Share Posted August 23, 2007 I'm just going to leave it for the time being. Until the local boneyard gets in what I need. I need to change my M/C too, so I might do some reading into that. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted August 26, 2007 Author Share Posted August 26, 2007 Is THIS a 297 ujoint? or are the non-cad axle-shafts just beefier? cause that's definitely a bigger axleshaft than any of my other trucks... Link to comment Share on other sites More sharing options...
DirtyComanche Posted August 26, 2007 Share Posted August 26, 2007 AFAIK those are 297X shafts. However, you have to measure them to be sure. Link to comment Share on other sites More sharing options...
