I buddy of mine broke his stock u-joint at the track.What replacement U-joint is out there that he can use instead of the weak stock u-joint.

 

Look for some Spicer U-Joints.

 

where do you find them or whats a part number?????

 

Spicer is the only way to go! Precision might have life time warranty, but it's useless when your busted! And they will fail faster than a Spicer will.

Case in point. A buddy of mine up here has a Toyota truck on 40" tires. He buys literally, 300 Precision u joints each year at the beginning of the season. He says they are at cost and that's why Precision. Literally every 2-3 times he drives this truck offroad, he has to change at least one joint. I kept on him about putting Spicers in and he kept bawking because of the cost. Well, one time we were out in the snow and he had to change one on the trail, in the mud and I chimed in about Spicer and he wouldn't be doing this if he had one. He called me names and said give me one and I'll try it. I told him to come by the shop and I'll give him one to try. 3 weeks later and several trips, that Spicer was still good and he came by PAID me for that one and bought more. This was last May and he's still running the same joints.

I have Spicers in my rig with 40" tires and they are still good after ~30k miles.

Yes, they are a little more expensive, but what is your time worth? And I gaurantee that one Spicer will last longer than three Precision's. So there you go, paid for itself.

 

This is the document I use to look up part numbers...
http://www2.dana.com/pdf/K350-1-DSSP.pdf

On the left hand side is 2 wheel drive cars and etc.... Then just do a search on Google for the "Spicer 5-153x" or whatever joint you need...

 

Good to know. How are the Brute Force joints at Advance or other parts houses?

 

They aren't Spicers are they?

The ony companies that I know of that make stronger/better joints are Alloy USA, Yukon, Bobby Long and CTM. And they vary from $40 to $200 a joint. Obviously the last three are rebuildable and for about the same price as a Spicer u joint and use bushings, not roller bearings. The Long's and CTM's are made out of billet 300M. Yukon is forged? 4340 alloy and the Alloy USA I believe is just a beefier forged joint, like the Spicer. In fact, I believe Spicer used to make them before Alloy USA brought them in house. But unfortunately these companies are limited on what joints they make - 5-760x (1310) and 5-806x (1480) is all they make, I believe.

 

^^^well are the brute forces or not????

 

No, they aren't Spicers. Brute Force is a Neapco brand. Better than Precision, but no where close to as good as a Spicer joint. If it doesn't say Spicer on it, it's not a Spicer. Spicer comes in a red and white box.


Here we go... I just found some strength numbers

 

This is what I replaced my stock u-joints with. They are made by Lakewood and much thicker than stock and works well.

That looks like a Spicer joint rebranded. The Spicer version of that joint is under $15. 5-3147X is the part number.

 

ok so is there a universal u joint part number for our cars?? im seeing all these different numbers for different brands and years of cars and whether they are running alum or steel yokes. i have an alum and im going to a steel and would like new spicers to go in it but am unsure of exactly what part number to get. so far i have come up with 5-795x.

 

If you are completely unsure, measure what you have. You will need the cap diameter and cross width (outside of cap to outside of cap). You will also need to know if you want greasable or not; internal or external clips, etc. The picture I posted earlier is an external clip joint.

Either post taht up, or look at the document I posted earlier as it will give you all the specs for all of the different u joints Spicer makes. Then once you find the correct measurements, look off to the right and it will show you the part number.

I'm a Jeep guy, so I'm not sure what the difference in joints there are for AL or Steel drivelines.

 

5-795x is the correct one for stock rear and stock aluminum d/s. thats the spicer part#. other name for that type of joint are 1344, S44, saginaw, or 3R.

but anyhow, spicer 5-795X is the right one, just replaced mine about a month ago.

im not sure if im allowed to post the link, but if you put the part# in google its the first one that comes up

 

^^^^^ok but will this same joint work for a factory steel driveshaft. the one i bought came off a 00 trans am i think.

 

Look through the first 5-6 listings. I just did as you suggested, and one of them had it cheaper than the others at $24.91. I saw them as high as $58 IIRC....

I'm not sure if it will work with a steel driveshaft, again I'm a Jeep guy. But if the measurements/snap ring placement are correct, then yes it will work.

 

im going to compare the two shafts to each other once the steel one gets here and i get mine off.

 

I just had my driveshaft yoke replaced and installed new 1350 u joints. The guy that owns the shop said he has broken more spicers than the solid (2-0799) Performance Dynamics. They are cheaper and I had him install a set and he guaranteed they would not break. (knocking on wood) They are listed as solid performance dynamics u-joints. PN 2-0799
