Can I ? (rear axle swap question)
Hi,
I have a beautiful 87 XJ wagoneer 4.0L.
My rear axle is a D44. I need to swap it with a D35 as mine has issues.
I find no local Cherokee expert so will buy a D35 second hand (probably from a 2.1 diesel XJ) and ask a professional to swap it.
But I have questions
- Will the swap be simple
- Are the rear shafts always the same (universal joints, length, etc) so I can keep using mine (whatever the transfer case / differential)
- What else should I take care of
- What else should I buy before starting the job
- What mistake should I avoir to do
Thanks
I need to prepare everything and bring everything to the shop.
And I feel it might nos be as simple a buying an axle...
Thanks for your help

For the love of God, do not replace that D44 with a D35. That's a crime against humanity, lol
Why not rebuild the axle? What's wrong with it?
Find a shop that specializes in driveline. Doesn't have to be a Jeep mechanic.

I will disagree on the driveshaft. The pinion length is the same for the two. But I agree, the D44 is a much better axle and it has huge aftermarket support.

The D35 is fine for a daily driving and moderate offroading. It's a bit weak for large tires, hardcore wheeling, and a heavy foot though. Also pre-1990 the D35 was a non-c-clip axle which has some advantages. If you have to swap, going with an 8.25 from a newer XJ would be a better choice. The 97+ have a little thicker shafts too. I *think* the spring perches are located in the same place through the years? The only rear axle swap I've done was into an MJ so I had to move the perches anyway (inboard as I recall, kept them on top to do a spring over).

Hi. My XJ stays on the road and does a lot of highway at 120/130 km/h.
I discovered the issue with the D44 when changing tires at a dedicated shop. When I push / pull tires in an horizontal axle they move about 0,5 cm in and out.
As the car just left a mechanical shop (Land Rover specialist) for a complete differential check (bearings, etc) for a significant price I went to it, a bit furious.
the guy told me the end of the 2 tubes (wheel side) are oval and not circular where the ball bearings should go. And this is the problem.
i didn’t have the issue before giving him my car. But what can I do ?
as Indisn’t see the problem I just repeat what he said Does it sound to you ? Or is it bull****. ?
I understand he used some glue to keep the bearing in place.
He suggested buying another axle.

Sounds like a bunch of nonsense to me. An axle tube rarely ever gets oval shaped and the chances of it happening on both sides is almost none, and who uses glue to hold a bearing in?

Fixing this is probably going to require pulling bearings back off the shaft and reinstalling the correct parts in the right order and orientation.

A D44 and the non C clip D35 have tapered wheel bearings and they have had a little side slop since they were first made in WWII. Don't let that bother you at all. It is normal. These Dana axles are not like your Euro cars. Their basic technology is about 60 years old. I have a D44 I just put together that has brand new everything that has that side play. My non C clip Dana 35 has it too. There is one thing about the non C clip D35 I don't like. The axle you have has a nice heavy duty tapered roller bearing for a wheel bearing. Most of the D35, especially after 1990 or so have a roller bearing that rides on the axle shaft itself. If that axle gets pitted from use you have to get new shafts to get rid of the growl. I realize you are across the pond but I think if I looked at it that it would be fine. That is a good half ton truck rear end and it is hard to knock them out

I’ll make a video to make it clear.
I feel like I need another specialist to look at it
tou convinced me to try to keep the D44

You didn't answer my questions.
