Any recommendations on a good rear axle shaft for a D44a?

I just got some news from the shop, saying the bearings are shot (I knew this) in the rear diff (a dana 44a) and he saw the right rear axle was worn where it meets the bearing on that side.

I looked up the parts, and his part quote matches both results found on RockAuto. Does anyone know where I might get a good used or new rear right axle for cheaper or at least confirm which part number will fit my Jeep?

From Rock Auto:
Quote:
DORMAN Part # 630302 More Information About this Part {#4856333} Length: 30-1/4"; Number of Holes: 5; Spline: 30
Includes Bearing, Seal, Studs and Lug Nuts; Rear Left; w/Dana 44 Axle $246.79

What I'm running into right now, is lots of dealers are selling for Dana 44, but don't specify Dana 44a.

A side question: What side gears would I need to get for my Diff? Apparently those are worn pretty badly causing a lot of wharbling noise in the rear end when I'm coasting, not so noisy when under torque. Problem is, I don't know much about a diff, don't have a way to work on one myself (apartment) and I've never heard it put as "Side gears" in all of my reading for diffs....

Thank you for your help in advance. I'm trying to save what I can, but fix what I must, before my honeymoon road trip next month

Side gears= spider gears. It's what makes a differential differentiate.

Thats the going rate for new shafts. They never have been cheap.

I've still got an old spare set, but doubt you want to wait on cross country shipping.

What'll it cost? I don't have to get the axle shaft right this second and it'll only take me an hour to slide into place. Zip is 98136

Also, any idea what the length measurement is all about (why there are two lengths for the same jeep and axle)?

You might as well get Yukon alloys instead.

I would like to know cuz if my shafts are shot when I get my 44a torn apart next weekend, I would rather spend a little more to get a way better product.

Those look to be correct for a C-clip D44A, but I would call and ask just to make sure. As a bonus, the price on Randy's Ring and Pinion for that axle is $198 - cheaper than the OEM one from RockAuto. A no-brainer if you ask me.

Superior also makes their ZJ D44A shafts for $150 each, I'm not sure how they compare to the Yukons in strength. The Superior site lists their PA5225 as a replacement for the Yukon axles you listed above, indicating the Yukons are likely the right shaft for the ZJ.

I was totally going to say that. I got Yukons and have been very happy with them. I have a d35 though...

I would definitely go with the Superior shafts over the Yukons.

Thanks guys, I'll check out Randy's Ring and Pinion on a new shaft for now. Don't need regearing or anything.

The spider gears however, I do not know for sure what part number to get as what I'm finding only lists for Dana 44, not specifying 44a or HD. I'm looking to get something cheaper than the shop quoted (250 for parts). I guess I'll check with Randy's on that, too.

Wow, found the spider gears on superior axle's site, too. Favoriting that store, hah!

Thanks everyone for helping me out on this. I'll upgrade both rear axles to something stronger when I've some play money (that is, if the new wife lets me have any, haha)
