J4000 axles

[marvilusone]

I'm looking at buying a 1973 J4000 for the axles to put under my XJ but I dont know what axles are under it? What did the 4000's come with from the factory? Woud anyone happen to know how wide these axles are? The truck is about 2 hours from me and I just figured I ask on here first to find out if it was worth going to look at.

Aren't the fronts a passenger drop as well?

Yes on the passenger drop
IFSJA.org is a great site for that info.

I would not use them. There is something out there much better for the same price. waggy axles 80-87 j20 axles. ford, chevy, dodge.

Stay away from the Closed Knuckled front. They Suck real bad.
I had them on my 64 J200 and the spindle bolt keeped striping out and leaving me on the side of the road (this happen 4times . also the seals on the closed knuckles really don't seal they just control the amount of lube that comes out.
