Wj wj axle swap ?????????

With the information that I have read on the forums about the dana 35.... If I placed 35 inch tires on my 2001 WJ it the stock d35 will explode!! What if f I get a front and rear axles from an 8cyl WJ the rear being a d44. Then I could change the gears either 4.10 or 4.56(what would be better) then would the axles be all set with 35 inch tires??????????

I know from searching and getting frustrated myself. The answers are out there.

I can tell you need a little more searching just because the front axles are all basically the same. They are all Dana 30's. So no need for the v8 front.

Also the axles you want depend on your wheeling and your purse.

If your just going to get groceries on those 35's stick with the 30/35. If your rock climbing put it on one tons

This WJ is my daily driver but I work in the same town that I live in. When I go wheeling some rock and some mud.

That is good about the front end a lot less work and $$$. Is the 44 from the v8 WJ the same as the 1 ton? I like the WJ d44 because everything is bolt on no fancy work.

D44a was built for a light suv. It can hold up to 35's but the reliability drops quickly. The front is also going to be pushing its limits. 35's are a big jump from stock.

Spend about a month searching. Then you'll understand that. I promise the answers you are after are all already on here.

After a little more searching I may have found another option.......... change the gears front and rear (4.56) Install a dana 35 Detroit TrueTrac Limited Slip (it is not a locker) and an assuie or sparton in the front. The tires that I want are toyo mt 295 70 17r they are 34 inch tires on the toyo website.

My question is how would the aussie only lock when 4wd is in play.

Lunchbox lockers, I.e. Aussie, spartan, only lock when torque is applied. When in 2wd no torque is being sent to the front so it won't lock up.

That is the biggest problem with a lunchbox, its all or nothing.

With selectables front and back, you can have 1 wheel pull or 2 or 3 or heck all 4. It just depends on what's engaged and what's not.

Not very many people are going to recommend that you keep that d35 though. It's your jeep though and depending on how you drive it you may be one of the lucky ones. I blew up a d35 on 245/75r16's. I guess I wasn't lucky.

It sounds like you have a lot better plan now!

Maybe I'm a special case, but I snapped the D35 on 31s with the TrueTrac. A Spartan front will practically be invisible when in 2wd (assuming you have a 242). All depends on how you wheel though. That being said though, I loved the TrueTrac that I had in my D35.

And WJ axles are FAR from one ton axles. Google Dana 60, Dana 70, GM 14 Bolt, Sterling 10.5 and you'll be in one ton territory.

Only option for the 44a is a used Aussie or Spartan.

Then how does the 44a always seem too rank better the d35 has a lot of options.

At this time I am running 265x65 17 (almost 32" tires) general grabbers with stock gearing. No lockers and I do go off-road from time to time.

Only thing the D44a has going for it is that its stronger than the D35. The aftermarket sucks for it.

Just another option.

Set it on 33's protect the heck out of it with skids and bumpers. Then throw on a winch.
That will get you down the trail that those 35's would run from. Plus you won't have to be as hard on the throttle if you don't mind pulling cable.


You said its your DD so, a protected and winched jeep is gonna get you home easier than just big tires.

Today I spoke with a person from East Coast Gear Supply (919-672-2705). As we were talking he said that I could get a 30 spline count Detroit locker or true-trac for the d35 the use the Dana 44 wj REAR SHAFT KIT into the 35 rear end, and replace all the bearings and it would be dam strong.

Has anyone done this ? It sounds good.

If that would work, that would fix some of the big weak internals but the housing flexes big time so you need to truss it. Although the d44a needs a truss also. You'll never know how much you need to build up your rig until you break it. There are a good amount of people that wheel the he77 out of d35's with no problem.
