----------------------------------------
Dana 30
----------------------------------------
Ring Gear Diameter: 7.20"
Cover Bolts: 10
Carrier Breaks: 3.54 / 3.73
Axle Shaft Diameter: 1.16"
Axle Spline Count: 27
Max Recommended Tire Size: 33" - 35"

Notes: Dana30 can be found in both high and low pinion versions. The Dana 30 is actually surprisingly stout for it's size. It can easily handle a 33" tire, with aftermarket shafts its usually pretty safe to run 35s on them.

Can be found in the front of:
84-01 Cherokee
87-95 Wrangler

----------------------------------------
Dana 35
----------------------------------------
Ring Gear Diameter: 7.562"
Cover Bolts: 10
Carrier Breaks: 3.31 / 3.55
Axle Shaft Diameter: 1.16"
Axle Spline Count: 27
Max Recommended Tire Size: 33"

Notes: The Dana35 is an all around weak axle, not getting around it. I would consider a 33" tire the upper limit of this axle. Its not if this axle will break, its when. Its generally recommended that you avoid putting money into the Dana 35. Running alloy shafts will pretty ensure when something breaks, its a ring and pinion, or carrier, or spiders, the axle just isn't strong enough to handle oversized tires. Spare stock shafts are never a bad idea, typically I try and make sure at least one person in our group is carrying spare Dana35 shafts. Its a Jeep enjoy it, when it breaks upgrade.

Can be found in the rear of:
84-01 Cherokee
87-95 Wrangler

----------------------------------------
Dana 44
----------------------------------------
Ring Gear Diameter: 8.5"
Cover Bolts: 10
Carrier Breaks: 3.73 / 3.92
Axle Shaft Diameter: 1.30"
Axle Spline Count: 1972-newer 30
Max Recommended Tire Size: 37"

Notes: Dana 44s can be found in both front and rear, high and low pinon versions. It should be noted that the Rubicon Dana 44s have a weaker housing than other 44s. Most all 44s are 30 spline shafts, but be careful some early 44s came with dinky 19 spline axles.

Can be found in the front of:
73-79 1/2 Ton Chevy Trucks
73-79 3/4 Ton Chevy Trucks
72-93 1/2 Ton Dodge Trucks
72-93 3/4 Ton Dodge Trucks
67-79 1/2 Ton Ford Trucks
67-79 3/4 Ton Ford Trucks

Can be found in the rear of:
87-89 Cherokee

----------------------------------------
Chrysler 8.25
----------------------------------------
Ring Gear Diameter: 8.25"
Cover Bolts: 10
Carrier Breaks: 2.45 / 2.56
Max Recommended Tire Size: 33

Notes: The Chyrsler 8.25 can be found in the rear of many XJs. Strengthwise, its stronger than a Dana 35, but weaker than a Dana 44. The biggest problem with this axle is lack of aftermarket support.

Can be found in the rear of:
91-96 Cherokees with 27 spline axles
97-01 Cherokees with 29 spline axles

Maybe that should go in the babe thread. Nice pic tho

[denverd1]

i thought it was relevant. a rear end and a jeep. :D

[prerunner1982]

No no I gotcha. Just thought since it was a sticky it might be good to keep on subject, but no my call. Like I said I like the pic.

[denverd1]

Ah I see your point. Mods, do your thing if you see fit. I'll try to behave myself going forward. In stickies, anyway.

Hey everybody i need help with a Chrysler 8.25 i just purchased and get get any info on the casting numbers online. On the caps it says 3723574 and wn26....anybody that can help me identify the axle spline and things like this with these numbers? Thanks

[4.3LXJ]

Do you know the history? What year it came out of? Cap numbers will not tell you much I think

[DRHCHEROKEE88]

Supposedly came out of a 96 XJ but my research says that some late 96's came with 29 spline or 27 spline and everything after 96 is 29 spline. Just in a debate with someone who is trying to say i went wrong by getting this 8.25 if it is 27 spline saying its comparable to a d35. im hoping i had 29 spline shafts so i could laugh in his face but i still think i have a good rear end to start with. Guess ill have to take it all the way apart and see what i got.

[DRHCHEROKEE88]

also i got this rear end complete drum to drum for 200 dollars so i think thats a decent price

[4.3LXJ]

Yes, decent price. Probably a 27 spine. However that rear end still has a stronger casting, which is the D35 weak point

[prerunner1982]

27 spline Chry 8.25 is stronger than a Dana 35.... a 29 Spline Chry 8.25 is just closer to being Dana 44 strength.

[Mudderoy]

The measured diameter of the shafts across the splines is 1.190" for the 27 spline vs. 1.277" for the 29 spline; a definite increase in size and therefore strength (all things being equal). These measurements are taken from the couplers of a No-Slip that I received that had one of each instead of the pair of 29's I required.

:link: (http://www.naxja.org/forum/showthread.php?t=23024)

From all that I could find the 27 spline 8.25 and the 29 spline are identical on the outside, so the only way to tell is to open it up and count or measure. I'd do both. :D

[DRHCHEROKEE88]

Yea the rear end casting is way beefier i did notice that. Well im thinking about just ordering 29 spline chromoly axles and a locker for the 29 spline. Gonna gear it to 4.88 or 4.56 , not quite sure yet. But thank you all for your input on this rear end i appreciate the help.

[sexjay]

love all the rear ends here!!
