I am being told by a seller that the ring and pinion in a Dana 44 from the back of a YJ are the same as the ring and pinion in a rear Dana 44 in a TJ. Does anyone know if that is correct?

Most US YJ's came with a Dana 35. Some are not c-clip versions, most were. I know not of export versions. But I do suspect if that was common, a lot of the US YJ folks would be after it as an upgrade. Possible, but I've not heard of it.

I have only seen one single Dana 44 in a YJ that I believe was actually stock. It looked stock because it had the exact same perches as the stock D35s do for the leaf springs and shocks and the pinion angle was the same as stock, as well as fully stock brakes and brake lines. I saw this on FB like 8-9 years ago. I believe the guy that had it was in Canada. Nobody else including myself had ever seen one before. I studied those photos for a solid hour and if it was not stock, they did a really good job making it look exactly like the factory Dana 35 stock setup.

IF there were more of those YJ Dana 44's floating around, I would guess that they would use the same gears and bearings as the TJ 44. Good luck finding more of those YJ 44's though, if they're even out there.

The info came from the UK reseller for Revolution Gear, I am not sure but I guess there were at least a reasonable number of export YJs with the Dana 44 in the rear. For UK sold RHD TJs the Dana 44 rear was standard as I understand it, so I would not be a surprise if that was also the case for latter UK YJs.

If I look at the Revolution Gear website they list a HP 30 / 44 package that is for YJs and XJs, I presume this is the kit the UK reseller is saying I need. But previously the suggestion on here was that the XJ HP 30 / 44 kit was not the right thing to buy for a TJ with an XJ HP 30 and stock TJ 44. I had therefore concluded that the reason must be because the Dana 44 in the XJ is different to the Dana 44 in the TJ, so now I am a bit confused.

That is possible. I really don't hear from hardly any export YJ owners, so it's possible the Dana 44 in the YJ flies under the radar that way.

I have seen the RGA gear package for the YJ/XJ 30/44 and wondered if they know something that I don't.

If it helps, the consensus seems to point to there being no TJ exports with the Dana 35, they all got the Dana 44 in them. Something similar may have gone on with the export YJ.

Possible. Just haven’t talked to any export owners to confirm that. Don’t see hardly any export YJs on the web.

I know not all UK YJs had a Dana 44 as a good friend in the UK has swapped his Dana 35 for a Ford 8.8 from an XJ. But I presume some must have been.

What I am trying to get my head around is why the prior view was that the gears for the rear XJ Dana 44 would not work in a rear TJ Dana 44. I think it may have been @hosejockey61 that made the point previously. I have no reason to doubt him, he’s clearly a knowledgeable chap. Just trying to reconcile this view to what the Revolution reseller in the UK is saying.

If there are specific points anyone can highlight I can go back and raise those with the reseller to try and get clarity.
 
I'm not sure why Revolution is saying the XJ/YJ 30/44 kit won't work in a TJ. I know of someone who bought that kit and used it in his HP30 swapped TJ that had the rear Dana 44.

The only thing is, 2003-2006 D44s have carrier shims outboard of the bearings, while 97-02 TJ and the XJ had them under the bearings. So if you are buying that kit and you have a 2003+ Dana 44, you'll need to add some outboard carrier shims to your order.

That's very helpful, and mine is a 2002 TJ so that is not an issue. Not Revolution that is saying that kit is not right, I thought that had been said on here.

For one thing, the HP30 uses reverse cut gears which means they won't work in a TJ low pinion axle.

As far as shim placement, you can put them wherever you want in or out.

I know that - last I saw he’s installing a HP30. Or was at least looking for one. If he was keeping the LP for sure, I would have stopped there.

True, for whatever reason I thought it might matter. I had a buddy with an 06LJ who ordered that kit because he was installing a HP30. The shims included were inboard style. His Dana 44 was outboard style. He called Revolution and they told him to order a Yukon outboard shim kit. Why, I don’t know 🤷🏻‍♂️. Because of that experience, that was why I figured I should list out the details of the kit and the carrier shim change - wasn’t sure if they mattered or not. I also didn’t know if maybe the carrier or housing is different based on what type of shim it came factory with. So it’s good to know either or can be used.

I don't believe you got that info from me. Regardless, I always tell everyone to order for what the axle is to ensure you aren't getting the wrong stuff.

Go to the vendor selling you the stuff. Misunderstanding somebody on here can cost you a lot of money.

Thanks for the clarification. It is the Revolution reseller in the UK that told me I can order the Yj / XJ kit. Without sounding like too much of a 'suck up' I was questioning that advice because of the weight I place on your knowledge of regearing TJs, based on what I have read here and your excellent Youtube channel. The comment I was referring to was in the recent thread where the chap in Riga was rrgearing and you were giving feedback on his patterns, but I must have misunderstood.

The general problem in the UK is everything is very Land Rover focussed and Jeeps so relatively rare. Even the small number of businesses that specialise in Jeeps focus on JKs and JLs, understandable as there are many more of them. So sound input on TJs is hard to come by.

Thanks again.

I just spoke to Revolution. The answer is some TJs can get the gear package, some can't. If you have a pre 2003 update TJ the YJ / XJ package will work, but if you have a 2003 onwards TJ you would need to buy the TJ specific Dana 44 gears and HP Dana 30 gears separately. Wanted to add a post in case anyone finds this thread in future with the same question.

They must be speaking because of the shims….because the gears are the same 97-06.

Also, I learned from the YJ parts manual that there were export Jeeps dubbed “KDX” that had the Dana 44. That’s where that came from.

The difference between YJ and TJ though can be a long vs. short pinion. The master install kits will also vary on what pinion seal, inner axle seals, etc. Don't forget Rubicon's throw their own curveball too with thick gears. There is always something with one year or another, so that's why I always tell people to call the manufacturer selling it.
