The bearing diameter and lockup on these are too big. Not going to work. My bearing cap is 0.947 inch and the lockup ring is 1.64 inches.

Here is the root cause of prop shaft vibration at high speed! The needle bearings were making deep groves on the joint.

Not compatible
this one could be for Dorman MDX replacement shaft. Hard to tell, saved that one a while back

I see. Those not compatible with OEM shaft. The only U Joints that fit the OEM shaft is from Rockford Driveline and the part number is 430-11A, $33 each. Only Rockford sells them.

How do you know about ’only’? I thought any one with internal snap ring would work if size is correct.

So much effort with 75% improvement and I just don’t like the slightly humming sound and vibration. I gave up and it’s in the dumpster.

Yeah the Rockford u joint installation is pretty easy however, I still have slightly humming sound and vibration. It’s a lot better than before but I don’t like it. After I removed the prop shaft it’s dead silent and no vibrations.

Back to enjoying front wheel drive only!
This thread covers a driveshaft that was purchased off of Amazon. Looks to be around $300. You could also try a local driveshaft shop if you have one available.

Can U-Joints be Changed???
Hi All, I've been having a lot of vibration when driving my 2007 MDX lately. My general mechanic tells me that U-joints are shot. Is it possible to change the U-joints in the MDX or does the whole drive shaft need to be changed?

It looks great and has all the positive feedback from the people who installed it.
I would try for that kind of money if it lasts a few years without vibration - great!

Also, the one from Dorman P/N 936025 sounds promising.

we dont have wagons they are different
Just thought I would add my experience:
I took my bad prop shaft to a local driveshaft shop just to see what they would say. I have done business with them a couple times before. This is a fairly large shop that has probably 20 employees and does race cars, pickups, classic cars, and commercial trucks. They said they could not rebuild it. They said they were able to get a new aftermarket assembly and have sold some with no complaints. I expressed my reluctance as I had heard of many of these not being well balanced. They said they would put it on their balancer and ensure it was balanced to 6000 RPM. $450. It's been on for about a month now and no issues so far. 1 year warranty.
More info:
I actually had a longer conversation with them. I originally asked them to just service the u-joints. They said u-joints are not serviceable. I asked if they could cut off the yoke and add a serviceable yoke that had the same size u joint. They said they simply weren't interested in the liability if another part of the driveshaft failed. And they couldn't build a new one because they didn't have the tooling to do the center joint. The center joints they do are larger and won't fit in the tunnel (ball and trunnion?). They know what they are good at and I don't blame them for not wanting to take a risk.
