hey i have searched and nothing what i am trying to figuire out is will a axle from a yj drop into a xj? i have a ford 9 thats fabbed for a yj and my brother wants it for his xj but before we pull both we want to know the9 inch isnt at my house so other wise i would measure.

 

Shouldn't be in Fabrication, but in Adv. XJ Tech.

The YJ rear axle is spring under.. XJ spring over
The YJ front axle is leaf sprung.. XJ coil sprung
They both had the same width axles.

Not a drop in, but cut and weld new mounts and it should fit.
I put a spring under MJ axle in my XJ by welding new HD spring purches and shock mounts on it.
Good luck.

 

Depends on what it's out of and what's been done to it. Most 9" axles are full width and would be 5-6" wider than a stock axle.

 

no the yj it came in was narrow arround stock width it was a old 40s truck axle it has a spring over pad on it just was wondering if by chance the perches were the same width apart

 

You will have to relocate the spring pads. That should be all you have to do if it was previously in a YJ

 

I think 4.3LXJ is correct. The spring pad width is narrower on a YJ, but is easily altered.

 

Why not go with a TJ D35 or XJ HP D35?

 

ok thanks
and d35s are gay its for my brother his d35 is going out if he wanted another d35 i would give gim one he wants bigger so i have a 9" out of a yj with 456 gears a detroit locker and 456 geara for a d30 so thats y

 

Where does one find a HP D35? Not that I'd want a high pinion rear axle much less a 35 but just curious.

 

why get a D35?!?!
