It's that point where you start looking at how much work you are willing to put into a 8.25 just because you have it, how long that work will take the jeep out of commission, and what the cost/benefit ratio works out to.

Then you do a quick online salvage search and find a possible factory D44 candidate in NC for only $125........How far do I want to drive for an axle house I'll have to rebuild? ROTFLMAO

How about a Ford 8.8 Swap instead? Easier to find locally, fairly easy swap into an XJ + Gives you a disc brake upgrade...

Requires welding of brackets, yoke swap/adapter, has c clip axles, welding axle tubes, will need to regear either the front or rear axle to match. By the time all that is done an XJ D44 is the same/similar cost and easier.

If you find an XJ D44 with the correct ratio, that is definitely easier, you just bolt it in, But they aren't easy to find. If the one in NC is the right ratio, and in a junkyard, getting it shipped up here for another $150 would be the best, simplest, and cheapest solution.

But the 8.8 isn't that hard of a swap.

It needs new spring perches and shock mounts welded, True.

It does need a yoke swap or adapter, and maybe a new driveshaft (Does the D44 use the same length shaft as the 8.25?)

It is a C-Clip versus retainer plates like the 44, so that is a definite disadvantage...

What Axle Ratio? the 8.8 is common in the junkyards with most of the ratios you could want, though the 4.10s are getting hard to find... I could only find one with that ratio in northern Virginia back in May when I last bought one.

It isn't necessary to weld the Axle tubes, You can, but you don't need to.

Also, E-brake hook up is going to be work for both swaps..

I beat an XJ D44 for 200K miles and only put brakes on it once. It was still perfect when I sold the XJ 10 years later. I'd take a 44 over a 8.8 any time.

Sorry if I started a political debate in your thread Dave, that wasn't my intention...

I always viewed the two axles as about equivalent strength wise, just seems a lot easier to find a cheap 8.8.

Dude, no worries! Let folks hash it out. Maybe someone will mention a pro or con I havent considered. Dunno?
