2wd axle parts vs 4wd

[rylee144]

I removed my 2wd axle and have a couple questions.

 

Are the brake calipers the same?

Are the roters the same? 

 

I believe they are. Thanks

 

I want to sell/get rid of the axle but don't want to discard items that would work on my new 4wd axle.

Calipers are the same rotors are not. Now if you had an 86- early 87 2wd axle, the knuckles and rotors are the same as 4wd knuckles until 89. But 2wd knuckles have the spindle built into it while the rotor holds all the bearings and such, thus making them incompatible with 4wd axles. Now I’m sure there’s someone out there who could be looking for those knuckles or rotors.

Just to confirm I won't need to swap the calipers i currently have. Thanks man.

Shouldn’t have to. Should bolt right up. 
 

No problem.

My old calipers would not fit. I swapped them but prolly messed it all up. Is the brake line put on correctly or do I need to flip it around?

 

Secondly is the hub nut on right? The castle nut that hold the pin seems to sink in a ways to far

What year is the D30? 
 

That nut in the center is more like a cover for the actual nut that holds the hub on while acting like a castle nut. Its weird.

No clue,  the xj was a 91 if I recall correctly. They swapped in a 8.8 rear so maybe that was swapped too.

Ok that could be the problem why the calipers aren’t lining up correctly. Kinda the reason why the 84-89 knuckles are sought after because they can hold better calipers.

That does not look right. Is the bearing in there -- and the big washer? Is there a bearing race behind the outer bearing?

 

[rylee144]

Mine is the 4wd option now, kind of. But well done sir! You are correct I am missing a washer.

Guy told me a Peugeot 5 speed cross member will support an ax15 transmission if you flip it around. Is that true?

Th AX15 has a drop in the middle. The BA10 goes straight across 

[rylee144]

I thought that too but the dude insisted. Lol 

[rylee144]

Could a guy get a shorter trans mount to make an auto cross member work
