Upgrading Axles

Finally getting a bit of cash flow and I was curious as to pricing for upgrading axles. I have a 2004 TJ with a D30 front and D35 rear. Both are geared to 3.07 and that needs changed. I want to get a 44 for the rear with 4.10s or 4.88s. Should I change the whole axle out and grab a 44 with the gears then regear the front? Also where would I find replacement axles either new or old it doesnt matter.

Its pretty easy to find an 8.8 but its gonna take a little more work to find a 44. And it shouldnt be that hard to find an 8.8 with 4:10 and limited slip.

So if you find a jeep 44 it should just bolt in but you will probably have to change the ratio. If you find a 8.8 with 4:10s you will have to add the brackets and a few other things.

Well ive seen some people say they are about the same but i have also seen this a few times

The axle shaft strength tested by Warn Ind:
F8.8= 6,500 (lb. ft.)
D44= 4,600-5,000 (lb. ft.)
D35C= 4,000-4,300 (lb. ft.)

8.8 FACTS, OPINIONS & HOW-TO'S (F.A.Q.) - JeepsUnlimited.com Forums

So this looks like they are pretty strong

There is also a vendor in the vendor area selling custom built 8.8s. Brackets, locker ECG I think it was. Alot depends on what tire size you want and how much/how hard your gonna wheel it.

Transmission I am not sure, but I have a 4L with a 5spd transmission. I am only really planning on running 33s or maybe 35s max. I have thought about the 8.8, but I would prefer to bolt on than finding someone to help weld on the brackets.

I got a HPD30 and Ford 8.8 with 4.88s ready to bolt in for $2,100 from East Coast Gear Supply.
