Precision 330a fits tight but I think thats what I used. I have one more sitting on the back seat of my truck, I could look and make sure that is the number.

 

Just by AAM joints and you wont have any issues of wondering whether it will fit or not. Ad they are way better than those percision ones. I wont run those in anything. I've snapped way too many in several vehicles.

 

What happens is when you press the old u-joints out, you actually bend the ears of the shaft closer together. You just have to bend them back apart a little. I can't believe someone would grind a new u-joint cap. Redneckery at it's best. LOL

 

Redneckery, great word for the day.

You are correct that a bent yoke could be the issue but it to correct it with out putting the joint off center is a trick.

 

Thats why I dont press mine out. I use the EBFH and hit the yoke and they pop right out....been doing this for 20 years and never done me wrong.

 

I wouldnt put AAM nongreasables in anything my original axle ujoints didnt last 30k GARBAGE!!

 

I've ran over 70,000 miles on one set and about 80,000 on another without issues. I replaced them as they felt a little loose to me. Never go with precision those things don't last for crap. I press mine out when changing them A buddy made a tool that helps keep the ears from bending. We also made a tool to help bend them back a little if they do happen to bend. I quit using the BFH when I bent an ear so bad I had to replace an axle shaft.

 

I found just the opposite my precisions have already outlasted the crappy stock aam joints. Being able to grease them i think has a lot to do with it. I would never put a part on my truck I cant grease over one I can grease it makes no sense to me.

 

You can buy greasable aam joints if you wish too. I don't run greasable joints for the most part. I've always been hung up on the fact there is less material in the joint if it is drilled out for a grease channel.

 

I'm surprised nobody actually hit on this. One of the biggest issue with the AAM joints ( I won't even go into the greasable, non-greasable ) is that there lock up diameter (cap to cap) is .010" smaller than any other joint (like spicer) So if you get a normal u joint, you need to take .005" off each side. Ever notice the AAM's are smooth on top, and most others have a lip? That's why. Also most other u joints are not manufactured as well as stock joints, so sometimes they fit because there tolerance is less (not much) but again different.

I plan on using Spicer joints and just milling off .005 each side. Much better u joint and greasable. I dont' mind if they go from wear, but if I can get double by greasing it, that's for me.

There are a lot of write ups about how AAM uses smaller yolks than other companies. I'm sure soon they'll sell sllip yokes and a rear yolk that accept normal u joints

 

I also used spicer and removed .005 off the cups. One fellow told me that the Dodge came with a 1485 ujoint and the longer ones are 1480s but I never heard of a 1485 so I don't know.
