Rear Axle Debate

Whats stronger? Dana 35 (Non C-Clip) or Chrysler 8.25" (27 spline). Shaft sizes are esentually the same. If you had one of each sitting there, and were going to put one under the rear of your rig, what one would you put in and why?

I'm not talking the 29 spline Chrysler 8.25", I know thats definatly stronger than the Dana 35. I want to talk 27 spline versus non c-clip.

The housing is a different length, so you'd need a corresponding driveshaft to fit one under a rig equipped with an 89 TC. You'd also have to check and be SURE the gear ratio is the same as your D30 front axle.

I have 2 of these early 8.25 axles and have heard they are no stronger than my D35 (which I am pretty impressed with so far on 33s), so they still sit in my shed awaiting buyers.

I'm talking specificly for the MJ buggy running 33-35" tires.

So if you had 1 of each sitting there, which one would you swap into it to run that size tires on a trail only rig that you'd wheel pritty hard?

I'm thinking the D35, simply for the fact lockers can be found used cheaper. But if that 8.25 is stronger and would last longer than I'd swap that in....

Yes I know neither is the strongest, but I own both axle's already and am trying to build this on a budget, maybe an axle swap would be something down the road....

Oh the decisions....

I believe that the chrco is stronger, due a few factors, mostly due to its increased axle tube size, they are both c-clip axles and you probably wont find much trouble with the clip itself. I think the chrco is also better due to the fact you can very easliy upgrade the axles by dropping in 29 slpine carrier and axles!!!! But I think the dana 44 is better yet than both!

throw the 8.25 in for now and weld the spiders.


when you have some money in the future, find some 29 spline shafts and carrier and swap them in.


if i was tight on money and needed to run one of them, that's what I would do

Josh,

I'm talking NON C-clip D35. I wouldn't waist my time with a C-clip D35. I'm specificly talking the NON C-Clip D35 vs. the 8.25"

Here is what I've come up with:

8.25
Bigger ring and pinion +
Bigger solid axle tubes +
Can't go any lower than 4.56 -
Is C-clipped -
Drum brakes -

D35
Smaller ring and pinion -
Weaker axle tubes -
Can be regeraed lower than 4.56 +
Non C-clipped +
Drum brakes -

Is it true that the biggest issue with the D35 is the fact the axle tubes flex under load and that leads to everything from broken axle shafts to trashed ring gears? I guess what I'm getting at is the 8.25" THAT much stronger than the D35? Is it worth me spending the 100 bucks for mounting stuff to shove it under the rear of the MJ?

I'm pretty sure the piece that breaks most on both axles is the shafts. I haven't heard of D35 tubes twisting, just AMC 20s. I would just stick with a D35 SOA setup for the MJ if I was you. Either way you'll have to reweld perches to get the axle centered...

I dont know for sure, but have heard that the 8.25 is marginally weaker than the d44, so in my opinion that would be much greater than the d35 clipped or not, and I may be wrong but i thought that the 8.25 could be geared to 4:88.

Well there are 2 D35's as well as 2 8.25" rear axle's to talk about. A 29 spline 8.25" is quite a bit stronger than the older 27 spline. Than you also have the C-Clip and NON C-Clip D35.

I am curious specificly about the 27 spline 8.25" vs. the NON C-Clip D35. I at the moment don't want to compaire the others, as I know where they fit into the line at. Thier just seems to be a debate about the 2 I'm curious about as far as strength goes.

1) D44
2) 8.25 29 Spline
3/4) D35 NON C-Clip or 8.25 27 Spline (this is what I"m curious about)
5) D35 C-Clip

well my jeep started life with a d35 non cclip and it broke on my second badlands trip.  i blew the sider gear which then ate the r&p or vise versa.  it is a weak axle.  however i think a cclip axle is retarded.  not to mention the 8.25 is a fairly weak c clip axle.  if it were me and i HAD to run a d35 or a 27s 8.25 (which i think u would basically have to have a serious threat on my life for this to happen) i would go with a dana 35.  i would truss the crap outta it cause a lot of the broken stuff happens when the housing deflects and the inner stuff goes boom.  trussing the axle shouldn't be hard at all.  truss the crap outta it, carry at least one FULL set of inners (yes that means new carrier, r&p, spiders, shafts, etc).  i would also try to get the spare r&p somewhat close to the right gear pattern on the carrier so you can just swap it in WHEN it breaks.  obviously its not gonna be perfect but it will get you off the trail and home.  i would expect breakage and try to drive lightly (i dunno if i know that term anymore actually, it happens when you quit caring about breakage...).  thats the best advice i cna give right now cause i'm tired and need sleep.
