Brand New 7290 U-Joint Failure
I lost the front prop shaft in my 02 Ram 4x4 a few weeks ago as seen in the pic below. I did not change the U joints like my dad as a kid told me to do when you get a new ride. So I got a new prop shaft to fix the front. I took the drive shaft out and went over to an old man in Vancouver WA that all he does is build drive lines and had him put in new u joints, balanced and painted for 175.
When talking to him, he only sells USA made Spicers that are non serviceable, aka non grease fittings. He saw a grease-able one a few weeks before me that had all four lugs ripped off the center of the U joint and told me to never use them. What he said is that they get over filled with grease, and since the seals under the cap is not as good as the non serviceable (non fitting) the grease is pushed out splitting the seal and then spins out all of the grease and then the needle bearings get ate up..
Last Sping, I had him build me a new drive line for my Duster with 1350 U joints on both ends (same as used on Ram trucks) cost me about 425,which is about the same as Denny’s before shipping. I did have to buy a new 1350 slip yolk and 1350 pinion flange from Diff Dr. which are rated for about 750HP...
1350 Transmission Slip Yoke
FORGED STEEL 10 spline 1350 U-bolt yoke package
He has the best prices for these that I could find on the net and when you look at the cost differnace vs the smaller 7260/7290/1310/1330 parts it was a no brainer for me as I’m going to be close to 500 HP soon..
Dr diff also has a strange drive line on his page...
