GreenGrandV8:
i found someone that emailed me about somethin on craigslist. he said hes got d44 front and back axles and was wondering if this would be a strong upgrade to do on the zj??? instead of the d30 and c8.8. let me know what ya think. thanks

Bill3753:
It really depends on what they are out of.

The 8.8 rear and a Dana 44 are really about a toss up, so I'd say its a draw there.

The front, like I said, it depends...

Some are too narrow to really be effectly used in your ZJ.  Others, are too wide.  To some extent spacers can be used to correct this (for narrow axles, not the wide truck ones).

Some have weak factory knuckles, but they can be converted.

Some have small axle tubes and I'd really stay away from those.  Being you say their older, you should be fine here.

All this being said, the 44 front will have definate advantages over a 30.

Basically, let me know what they are out of and I'll hook you up with the 411.  If you don't mind me asking, how much is he looking at for them?  That makes a difference too.

the only real upgrades for the over the d44 has over the 30 is shaft spline count ring gear size and manual hubs you will have to get new wheels if you want to run these

Mr Rock:
The real question is how big of a tire are you planning to go to. In the front I have a YJ HP D30, aussie locked, stock TJ axles with upgraded u-joints (the "alloy X" ones). An all stock 8.8 with a lockright in the rear, running 35's and I do not baby it one bit, but it is on a YJ so my rig is a bit lighter than a ZJ. To be honest I'm not sure how much bigger a tire I would go on the D30. Nate runs 36's on his LP D30 and he blew a rink gear if I remember correctlly.

Flex:
It's hp30 and I ate the spiders gears once and broke an axle shaft once. But I push it pretty hard and the 36 are a very sticky tire.
