Default YJ full size axle swap

I got a couple questions about swapping out my d30 and d35. Can you run the stock yj springs and just change the perches on the axles? And does any one have pics of there swaps?

Yes

With the wagoner axle it is easier to just use stock perches in the front and outboard the springs

Why do an axle swap then?

If they did have the diff on the correct side, I would recommend limiting straps in case you get some flexy time to keep it from articulating further than your driveshaft.

The most common breakage in a D30 is the u-joint. However, it's the same size as the 10 bolt, so no improvement there. If you want a wider stance, just go with wheels with less back spacing. I don't think you are gaining much with that swap.

Wj knuckles
The passenger side knuckle has a high steer arm for the drag link
And I agree that you wouldn't be gaining much with a 10 bolt over a Dana 30

My only two cents to that is that if you have it on a spindle, you might end up with cheaper replacement parts because of the unit bearings... and locking hubs

I would get rid of that D35, find a 8.8 to put in there.

I thought the YJ joints were the smaller ones, and they only "upgraded" to the larger joints in 96-01 XJs and 97-06 TJs

Also the most direct "bolt in" full width axles for your rig is a set of axles out of a 78-79 Ford F-250 or 350 (or a fairly rare supercab 150)

This will get you either a 44 or 60 front and either a 9 inch, Dana 60 or 70 rear.

The spring perch width is very similar for the front axle. After that you still have to fab steering, shock mouts, etc. Front driveshaft may or may not work.

IMO this would only be if you are looking to go big and wide. For a YJ, building a 96-99 HP 30 and a Ford 8.8 is a nice combo up to 33-35 inch tires.

I can't answer that. I just remember that my 90YJ had 760 joints in it. How/why, I can't answer.

And I had a 2000 XJ with the smaller joints. Weird.
