D30 swap

I've got a line on a new axle. Was wondering if a Dana 30 from a 95 YJ will bolt directly into my 92 YJ? Is there any sensors or anything I need to be concerned with? Any other suggestions to be on the lookout for??

Yes it should bolt right up. Just make sure the gear ratio is the same as the rear.
Why are you doing this?

The one I'm looking at has lower gears(4.10), that's why I'm interested. Also looking for an 8.8 with the 4.10's.

That's the best way to get the 4.10 combo. When you look for the 8.8 look for axle code 42 for the open 4.10. I'm not sure what the code is for the posi-lock version 4.10. The code will be on the door and/or door jam. Somewhere in that vicinity.

Axle codes to look for are: D2 for posi-lock and 42 for the open 4.10

I have about 10 exploders in the local yard and none have these axles. I have found about 1/2 dozen D4 (3.73 Limited Slip) axles if anyone is near Chicago and wants one. $75 on Tuesday (Tuesday is 1/2 price day). I'll even meet you at the yard and help you pull it, if you agree to help me pull mine once they get in a 42 or D2 axle. :-)

I've heard the only ones with 4.10's are the Eddie Bauers. Does anybody know if this is true?

this is not the most reliable way to get a 4.10 exploder 8.8 i did the a few months ago and i verified the diff tag and got hosed it had gotten 3.08's not the 4.10' next time pop the cover and check the ring gear

No. Generally the 2 door sport has a 4.10 and others with a factory two package. You will have to check them all.

There is always a chance that the axle was replaced or re-geared at some point so it's always best to double check.

Well at least verify by spinning the axle and counting the DS revs- the door guide it just to get you to look at the right vehicles! :-)

Well now I know for sure not all the EB's or 2 doors have the 4.10's. Been to the pull-a-part today and not a single one with 4.10's. So much for those theories.

Nope. Direct swap.
The D-30 in the '90 to '95 are the same except the '95 has bigger u-joints.
The D-30 in the '87 to '89 are a different axle at the ends, and will not match up to the '90 and later axles.

So what would have to be changed to get an 89 d30 bolted onto a 95 yj? I'm doing the same thing as the original poster and the two axles look pretty much identical.

so are the 95 yj d30's 4.10 then? From the factory, I mean, I realize they could have been changed.

True but it's the easiest way to identify what explorers to start popping the covers on. When I got my 8.8 I popped the cover and checked the ring gear. At first I didn't think it was a 4.10 because I wasn't getting 4.1 turns from the pinion with a single turn of the axle shaft. The spider gears were throwing it off so I popped the cover and checked it that way.

The axles are identical until they get out to the ends. The axles themselves have two different size lug flanges so the rotors are a different sized hat.
The mount for the brakes are different too. The rotors are a different size hat so the brake pads and calipers have a different radius. The different calipers have different brake lines that attach in a different spot, so the brake lines are not interchangable.
I'll find the thread where I posted pictures showing the difference.
So you will need all the brake parts including the brake lines from the '89 to convert your install. I put a '95 in my '88. My son put my '88 in his '90 and I used his '90 brake parts and lines on my '95 axle in my '88 Jeep.

No. The four banger engines had 4:10s and the 6 bangers had higher gears like 3:55 and 3;07'S. The years made no difference in gear ratio.
