Im running 36'' TSL's on my 89 YJ jeep with Dana 30 for front and 35 for rear. My question is would I be better off if I upgraded axles on same or to change out to 8.8 rear and D-44 for front. In the long run would the oringial axles hold up if upgraded or would it be cheaper to go ahead with change out of axles? I only have a 2.5 liter engine now but in future looking to do a swap.

Ur front axle will hold up just fine but ur rear isnt going to take the beating. Cheapest way I upgrade the axle shafts up front to a one peice on the passenger side from an xj and tj. That will give u the same size ujoints as a dana 44. Then out whichever u fins first to match in the rear, wether it be 8.8 or dana44. I run a similar setup on 36 iroks and have no issues with breaking. An my engine is a slightly stroked 4.0. Bored 30 over and ported an polished head.

Thanks for advise. I will look into a one peice axle shaft for front. I guess I should have said that when I do get to swap engine Im thinking V-8. Would the Dana 30 still hold up?? and for the rear I will have to look around and see what I can find.

An 89 model should have the heavy D35 with the finned 10" brakes
Behind the 4 banger you should be fine
A V8 is another story

We have a 92 with the 4.0 and put the heavy 35 in it with 4.10s and 33's
Hasn't given us a problem to date

You've gotta throw a lot of money into that Dana 30 for it to handle those tires. The rear axle is out of the question.

So what I'm understanding so far is the best thing to do is to just go ahead and change out both axles to something bigger. Especially if Im planing on engine upgrade in the next year.

Yep. And if you plan on bigger tires in the future you might as well go tons. Or at least a 60/hp44

No I think Im staying with this size tires. When I started my jeep I sat down and made a lisit of thing I wanted to do and thats what I stuck to so far. I started with the lift, tires, transmission, and engine ( already changed on 2.5 liter for another newer one, budget was tight then) But Im really trying to stick to my lisit. Only thing was I wrote get advise when I got to axles. Thanks for all your advise

An 8.8 /hp30 with some upgrades (shafts at s minimum) should be OK do you then.

Or 44s. Either way.

Ive been told it would be hard to match 44 with a YJ how much true is there to that? But was leaning to 8.8 and try upgrade D30. D44 not out question yet

I prefer the 8.8 route myself but you can always get wheels with more back spacing to get the width closer to stock if you go with wider axles.

Or, you can custom cut down the axles as well, but that's not the route I'd go.

The 8.8 swap is about the best bang for your buck unless you own a junkyard specializing in one ton trucks.

What were you doing and how old was the build on it?
