D44's out of a Jeep Grand Wagoneer - Fit TJ?

Will the D44's (Front & Rear) out of 1988 Jeep Grand Waggy work under my 1999 TJ? If so, how complex will it be to get them to bolt up properly? Is there anything that I'd have to do out of the ordinary to get them to work?

Thanks for your help.

They are going to be full width axles. Probably will have to grind off all the old mounts and weld on the mounts needed for your TJ. Then get the steering, brakelines, and drivelines set up.

You will need a set of TJ brackets or a truss system like TNT Customs has that has the brackets built-in. It would be a similar swap as any other non-TJ axle would be....brackets, brake lines, steering.

This is a swap I have been considering. Since you would have to do the same thing with say, JK D44 axles, these seem like the less expensive route since they initial buy-in is much less.

why swap in 44s?

the ammount of work to put in a 44 is the same as a 60.

the 44s max tire is still a 35 much bigger you still break shafts and u-joints. I wouldn't waste your time doing waggy 44s into a TJ. an HP30 from an XJ would be a better use of your money and time if your planning on 35in tires.

From a strength standpoint, the rear would be the only one worth changing, and that would be a lot of work. Width would be an issue, bracketry for TJ springs and control arms would have to be attached and the old Wagoneer perches would have to be removed. Track bar bracket would need to added too.

If you had to adjust the width, then you'll have to get axles, or have the stock axles cut to size and resplined. You'd also have to get a new carrier and gears, since the stock ratios for a 88 Waggie are either 2.73:1 or 3.31:1.

I'd say opt for a Ford 8.8 axle instead, width is correct and just leaves the bracketry to deal with.

I looked into it its alot of work, and really there are better things to put up there. the full size axles will sit out wide from your jeep, you'll need to weld or buy new spring mounts, your break lines are too short, etc. for less work you can find a Dana 44 rear out of some Cherokees or a Ford 8.8 is also very popular. to me its more work than its worth. I wouldn't. that isn't to say it CAN'T be done, just that there are better ways.

Thanks everyone. The reason I was asking, I broke some teeth out of my stock/ open D30 front pinion ring this weekend doing some hill climbing. A friend of mine has both front and rear D44's out of an 88 Wagon that he's been trying to sell me for a while now. Having read everyone's post, and doing some other research, I think I'ma pass on them and do something different. Not sure what that is yet? D30's are pretty tough axle's. I just may beef it up a little. I've already got an Aussie Locker (it wasn't installed) so while I'm having the pinion and ring replaced, I'll just have them install it then.

Thanks again everyone.

Try a high pinion 30. The gears mesh on the drive side compared to a lp30 where they mesh on the coast side. HP's are stronger.
