Found an 8.25 on CL

I believe the Dakota rears are wider. It may be 6 lug, I know the 93's are. I think you would be better off getting one from a 97+ XJ. JIM.

ABS won't affect the swap if you don't have ABS, the only difference in the axle hardware is that the shafts have a "tone ring" pressed onto/machined into the part just past the bearing surface (I think.) There are sensors bolted to the backing plates but simply unbolting them or cutting the cables off/tying the cables back solves that problem.

What I'd be worried about is more what Jim noted before me, the width/wheel stud pattern. You might have to narrow it down (unless you want to run wider tires / wheels with more backspacing, then it could be good) and/or move the spring perches. The price is good though, at least around here junkyards want a hundred bucks a pop for axles.

I happen to have both a Dakota and XJ so, I can tell you that the biggest difference is the Dakota is spring under, and the XJ is spring over. The lug pattern on the Dakota is six lug also.

$60. sounds good, but it would take a lot of work to fit the XJ. Around here you can pull a 29 spline 8.25 from an XJ for around $125., would prolly be cheaper in the long run.

Is there a way to tell if an xj 8.25 has 27 or 29 spline without pulling it apart? And this is the axle shaft spline #, right?

Axles

Front Axles
Dana 30 high pinion - reverse cut - 27 spline, 1.16" diameter shafts, 7.13" ring gear - used 84-99 (some axles through 91 are vacuum disconnect, 92+ are non-disconnect, 89-95 with ABS have 5-297x u-joints, all 95+ have 5-297x u-joints, all others have 5-260x u-joints)

Dana 30 low pinion - standard cut - 27 spline, 1.16" diameter shafts, 7.13" ring gear, 5-297x u-joints - used 00-01

Rear Axles
Rear Axle pics including non stock ford 8.8 and 9" and D60- http://memimage.cardomain.net/member_images/1/web/325000-325999/325707_182_full.jpg
(Note on Dana 35 axles sometimes referred to as Dana 35C - The "C" does not stand for c-clip. It stands for "custom" meaning it came from Dana unfinished.)
(Note on 8.25 axles - none of these axles were used on XJs with ABS brakes. If you have ABS, you have the Dana 35. Without ABS you could have either axle. 8.25 axles are c-clip)

Dana 35 non c-clip - 27 spline, 1.18" diameter shafts, 7.58" ring gear, 2.62" axle tube - used 84-89
Dana 35 c-clip - 27 spline, 1.18" diameter shafts, 7.58" ring gear, 2.62" axle tube - used 90-01
Chrysler 8.25 - 27 spline, 1.17" diameter shafts, 8.25" ring gear, 3" axle tube - used 91-96
Chrysler 8.25 - 29 spline, 1.21" diameter shafts, 8.25" ring gear, 3" axle tube - used 97-01
Dana 44 non c-clip - 30 spline, 1.31" diameter shafts, 8.5" ring gear, 2.75" axle tube - used 87-89 on some(not all) XJs equipped with towing package.


Gearing

3.07 - used with 4.0L engine / manual transmission
3.31 - only available on older (pre87?) 2 door XJs with "Fuel Economy" package

That's some good info there! I really just want to lock the rear end and am afraid to do so with my current D35 rear - plus the drum brakes are shot on this axle. I don't plan on going bigger than 32" tires but still..

This narrows down the search a lot, thanks for the info!
