Differentials used on 88 GW

I'm trying to find a right rear axle shaft for my 88 GW and I'm getting conflicting messages. Some places say that the differential is a Dana 44 and others a Dana 35.

Are the front and rear different? Is there a way to tell them apart?

Thanks............

The 1988 Grand Wagoneer came with Dana 44 front and rear.
Tell whoever giving you conflicting message that you have a Full Size
Jeep and not a Baby Jeep with Dana 35.

One more question....

Thanks for the info. Do earlier grand wagoneers - 86, 87 - use the same differential and would the shaft from one of those work? A local wrecking yard has an 86 and I can get the shaft for a pretty reasonable price. No 88s in the area though.

Yes, they should. Earlier one's used the AMC 20 Rear diff, but a stock '86 would have the Dana 44's front and rear.

86 was a change over year for the diff. Some of the early 86 may have the AMC 20. Take you old one with you to the wrecking yard.

The AMC 20 axle is easy to recognize.The cover will be a smooth round cover like 1/2 a basketball. The Dana covers aren't round and have the protrusions for the ring gear. The 86 will have a front D44 regardless if early or late 86. Compare the front to the rear. It'll be obvious. Remember the front and rear gear ratios MUST match to what you already have in your car. It's expensive if you need a shop to swap R&P's just to use a junkyard axle.

If you just need the axle shafts, don't worry about gear ratios as the rear D44 shaft you need will be a 30 spline in both a potential D44 equipped '86 and what you have in your 88 rear D44. Do yourself a favor and take the junkyard axle shaft to a shop to have the old wheel bearing removed and new seal, new wheel bearing, and bearing retainer pressed on. Also have the shaft checked for true.

Just found a screaming deal.........

Just found a screaming deal on a shaft from a 90 GW. Any reason why that wouldn't work on my 88? I assume they both use the Dana 44 rear end.

Well, you could always crawl under your rig....measure w. a tape measure from the backing plate to the center of the pumpkin..........and then compare. And while you are at it, you could look at the pumpkin(maybe take apic) and compare it to the one you are looking at for parts.

Internet knowledge is worth what you pay for it,,,right?

Downside to online forums

Down side to trying to get information from an internet forum is that the anonymity gives smart-a..es who would otherwise stay quiet the courage to make some useless remark The good thing is that for every one of those there are several decent people who actually try to provide some positive input.

I’m just trying to get all the information I can prior to driving a long ways to get this part. I was hoping that someone on this forum may have already done what I’m getting ready to do and maybe alert me to any pitfalls – which is what I would do if someone posted a question about something I’ve experienced. For all I know Jeep may have made some subtle change to the shaft between the years 88 and 90 - something that couldn't be detected with a tape measure and a camera.


Thank you to all the members who have helped me with this and other issues.

Those '90 shafts you found are interchangeable. you are good to go.
Do put new bearings, seals, and bearing retainers on there and do both at the same time like was said before.

Why are you replacing it, did you break one on a trail?

If you fragged bearings and chewed up a shaft, pull EVERYTHING out of both sides and make sure it's surgical clean. I just played that game a couple months ago. It sucks but otherwise all the junk will get inside the new bearings and you'll be doing it again. Also, DO spring for the good replacement bearings.
***
FYI- J20 wasn't being a jerk. He's a good dude from what I can tell, long time member, and has good info. He's just tellin' you if you ain't 100% sure or are getting conflicting info- go check it yourself. You are the one spending the money and that way can only blame yourself.
