Re: axle swap suggestions

I never understood why people think the 8.25 and hp30 are terrible...

I've seen a Chrysler 8.25 with welded gears stand up to a small block making 500+ horsepower at the crank. In a 1/2 ton truck. On drag slicks. At the strip. So I'd say that's plenty good enough in a small SUV too, again, especially if built. A factory tow package XJ Dana 44 MIGHT be marginally stronger, but also difficult to find. If you absolutely have to have something bigger in the back end, swapping in a Ford 8.8 is a popular choice.

If you want something better, ford 8.8 is the way to go. Its stronger than a d44, and fits with minimal work .
D30 ... well, its not a great axle, but swapping that Is more involved. I beefed mine up, when it goes I'll replace it, but to run something better, like a d44 or d60 takes some work , you need a decent amount of clearance. ,
I like my HP30, I'm running it bone stock with 4.10s and locker on 35s, she's great. Granted I'm stock HP, but none the less...
