Will a front ZJ Dana 30 fit in a TJ?

I have a 97 TJ and it started leaking gear oil. I brought it in and they said i have a bent front axle housing!!! I have been looking around and tj axles are to much for my wallet!!! Will a front axle from a ZJ Cherokee fit in my TJ?. It is a Dana 30. Or is there another alterative way to fix my problem? Possibly bend it back and put a truss on it? Any tips would be great!!

Where is it leaking from? A pic would help.

I am pretty sure a ZJ front axle will not work the brackets are in the wrong spots, but an XJ Cherokee has a front high pinion D30 in the 99s and older that is a direct bolt in to a TJ, and is and upgrade over the low pinion D30 you have now. The 2000-01 XJs had LP D30s that are also a bolt in, but not an upgrade.

A ZJ front is identical to a TJ front with the exception of CV joints in the axles.

Look for something with high pinion. Also don't worry about brackets, they can easily be replaced. It will probably cost you more to search for a direct bolt in d30 when you can just find any HP D30 and get new brackets.

Or for about 8-900 dollars you can buy a brand new HP D30 from East Cost Gear Supply and have it custom built. They also sell just the housings for 150, don't think the carriers and gears are interchangeable, but if everything else on your old axle is still good it can be reused.

The guy that's saying yes is doing so because he helped swap a set of TJ axles under a ZJ. The front is a straight bolt in and the rear has to be modified to work.

Make sure it's the correct gear ratio!

Yes a ZJ front axle will bolt in. The only downside is the weaker stock CV axle joints but you can swap in your u-joint axle shafts and keep the CVs for spares.

Confirm that gears and carrier from a d30 can be swapped into a HP D30.

You can not use low pinion gears in a high pinion axle.

97 4.0 manual TJ's came standard with 3.07 gears

but...

97 was the only year that 4.0 manuals had an optional 3.55 gear ratio.

Try and check your diff covers for a tag that has your gear ratio.

The front D30 from an XJ, MJ, TJ, ZJ are all interchangable. I had a 97 ZJ axle in my TJ for a couple of years, now it has a 89 XJ axle in it. Some ZJ had CV but I think the majority are u joint axles. I bolted my 97 ZJ axle in from caliper to caliper, and it was 100% identical to the 97 TJ axle.
Old XJ axles had smaller u joints than TJ but you can pull the axles from your TJ and slip them right in. The thing you have to watch out for is there were 3 combinations of hub/rotors during the run. Loosely speaking there were pre 1990 hub/rotor; the 90,s rotor/hub; and 2000 and up rotor/hub. Each model seems to have changed in a different year so you would have to seach to find the exact date.
