I was having a hard time removing the u joint. I don’t I can do it without proper vise and hydraulic press.

 

Watch some YouTube video. It can be done with ball joints tools with a big c clamp. You can rent those from Autozone

Trying to replace U-Joint on a prop shaft

I was under the impression that it's not worth it. Balancing this propellershaft is really tricky. There are no OEM separate U-joints being sold and third party repair more or less = brand new OEM propellershaft assembly.

But do let us know how it goes.

 

Is it like this video? If not, why?

I’m sure it can be done. There’s nothing special about a u-joint. Just have to match the size correctly. I’m guessing they don’t want to replace them as it may not be balanced correctly afterwards and cause vibration. My boat was the same way - Volvo wants you to replace the whole part. I took a chance and just did the u-joints and had no issues afterwards. That video is pretty much how it’s done - using a socket that matched the ujoint diameter a hammer and a big c-clamp. Some will have inner or out clips holding it in. They do have rebuilt ones on Rock Auto so they can be rebuilt.

 

I think finding the correct size of the new u-joint to fit is probably hard. If I measure the inner diameter of the yoke is 3/4 inch what is the correct size of the u-joint that have a snug fit?

 

Only way to find out is take it apart and take it to a place like NAPA and see what they have.

 

Got the suckers removed and trying to search for the U-joints that will fit.

 

Btw, how did you get it out? What kind of tools did you use? Thanks

Ok. Do you know what is the part number will fit? What about Rockford brand?

 

No. But I searched it up on advanced auto parts, lots results show up. You probably need to get in a store. Bring a caliper.

sockets, short socket extension, vise, 5-lbs hammer and lot of elbow grease and pounding . Took me 3 days to get them out. Watch the video I posted very closely and you can do it.

 

This is the correct u joints from Rockford 430-11A
This is my measurements:
Bearing cap = 0.95 inch
Lock up = 1.64 inches

 

My measurements:

lockup:

Bearing cap:

 

I like this video a lot better. No hammer etc. Soft persuasion.

 

Not every man and woman have a 10 ton press but everyone has a hammer and socket

 

Looks like the Rockford u joints is prone to snapping if drive your vehicle hard according to this guy. This u joints (430-11A) will fit on our vehicle

 

 

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.

 

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.

 

What happened? You put the Rockford joint on and it didn’t work well?

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.

 

Gosh, what are you going to do? $700 for dorman or 1k for OEM?

BTW, it could be rear differential like the other guy

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.
