it worked but ...
it worked! but i am not sure if the tolerances are a little too big on the splines when it was made , i had to buy three different brand new axels to find the one that fit, it saved me a lot of money for sure, i did not use the bearings included on the kit honestly they look very cheap made i did not want to risk it and used the old ones ,be aware people .

The story on the O-rings
Excellent, excellent kit. I’m very happy with this. I bought and personally installed this on my own 2017 1500 Ecodiesel. The ecodiesel oil pan is much tighter to the differential extension housing then the hemi or v6. One bolt in particular is a pain. I used a wobble extension and 12mm 12 point, and a 13mm 6 point for a little extra slop - the bolts have a 12mm head. I was very careful not to round off the head. Anyway, the O-rings. The kit comes with three. The two thicker o-rings go on the intermediate shaft on both sides, on the outside of the metal dust shield. The thinner o-ring is not useful, throw it out. It’s intended for the longer intermediate shaft. If you look really closely at the old one, you’ll see a thin o-ring by the cv axle splines. The o-ring left over in the kit is too thick. This o-ring is unneeded with the brilliant rubber dust boots included in this kit. Be sure to generously grease the splines with go into the CV axle. I also lightly grease all bearings in this kit, especially the smaller needle bearing. Yes, they get splash lubrication from the differential, but it make take a bit before they get it. Also, before you do the job, drain the differential, as the oil will interfere with the RTV you’ll need to apply on the extension housing.

Great fit.
It fit my 2015 ram 1500 4x4 perfect. Hundreds of dollars cheaper then OEM. No issues after a few hundred miles.

Great Money Saver
Have a 2015 ram that the cv clip rotted out and round out the shaft, looked into repairing it and found Ram says this is not serviceable and a whole differential replacement is needed, which is thousands, found this and figured i would give it a try for the price, if your mechanically inclined, it’s a fairly easy replacement, just takes a little time, but well worth the money saved, read that some people had to shave it a bit, but in my experience I did not have to do any modification. I’ve put about 10,000 miles on it sense the replacement and the truck drives smother now that the cv isn’t wobbling, and have had no issues with it

Nice kit
I replaced my front driver and passenger stub shafts with this kit about 1,000 miles ago and the quality is excellent. The dealership wanted $4,500 to replace the entire front differential, but this kit solved the problem for way less. The parts show great workmanship and the included dust boots are a nice touch to prevent future corrosion. The job was straightforward, though I recommend using an oven and freezer to seat the roller bearings and make sure you have grey RTV ready for the passenger side intermediate shaft housing. I chose to reuse my stock needle bearings, but the kit was very complete. It’s been 1,000 miles and everything is running smooth. Highly recommend for any Ram owner doing this themselves.

Worth the the price point compared to OEM
Everything fit as it should and came with extra shaft seals. The CV Axle cups could have a tighter seal though and the intermediate axle splines to 4x4 actuator had burs that had to be stone polished for proper operation. Also, had to out source C clips, the ones provided did not retain tension once installed.

Great for the price. Only use the part you need. Don't install both shafts. No need. Everything worked great. Take your time installing and make sure you use a press. I only used the RH shaft and the 1 seal. Threw the rest in the garbage. Make sure you replace the outer CV shaft as well. Great bang for your buck. NOTE: requires MOPAR axle retaining clips. The one's in the kit do not work. No biggie.

Installed on Ram 1500 classic, Parts fit and are working great. Was a bit labor intensive to change out, but way cheaper than getting the stealership to do it!

Awesome product. Comes not only all the parts you need to fix the Ram 1500 passenger side intermediate shaft issue but it also comes with boots to prevent the issue from coming back AND even has spare seals in case you flub one. Used this kit on a 2016 4th and 2019 5th gen rams. One item of note, consider either getting a cheap bearing press for the capture ball bearing that fits onto the shaft or bring it to a machine shop and get them to do it. I froze the shaft and warmed the bearing and even added gear oil to help it on and I couldn't get the bearing more than halfway on. I worried I'd damage the race with a Mallet and punch and my press was 150mi away at my shop. A machine shop pressed it on in 10sec for me and didn't even charge a $. Thanks for supplying this product at such a cheap price. Heat a 5k repair at the dealer.
