U-Joints..quality not quantity
 

Hey guys, well I was going over the truck today and I found my front u joints are getting some slop. I had a hunch that I was going to find this as I have been getting a very slight humm around 70mph. My question to you is what u joints are you running? Id like to get some greasable ones to save myself down the road. I perform regular svc on my truck so is like to keep them lubed. My truck is a 05' 2500 ccsb. Thanks again.

Are you talking on the front drive shaft, or the front axles??

Front axles. Sorry bout :argh:

May want to check and see if Napa carries them. They'll be a Precision brand universal. If Napa shows a listing, but none can be found, your probably gonna be stuck spending some moolah at the dealer. :ouch:

I'll check with napa. I'm an automotive tech and their our biggest supplier. Didn't even think of them. Thank you. Ill still be taking suggestions ad ill be doin this myself.

Napa part number 464 is for the one ton axle. Greasable heavy duty. I was just there doing ball joints and axle u joints.

Thanks for the input. I will be checking.with napa tomorrow.

Greasables are not necessarily better. 95% of them do not get grease all the way through. They can actually fail faster than the greaseless.

I've read that if you don't get greasable, take the caps off and add a little more grease
. Is that ideal or just go with a good brand sealed?

Rock Auto carries the precision 464's also. That is where I got mine.

Thank you for the input!

I have NeapCos in the Driveshaft and precision in the front axle...they have right about 200k on them without issue. My OE didn't even make 75k...

I think lack of service or poor grease is more the cause than the joint being greaseable.

My center carrier bearing was bad, so I had to replace it.
Truck has 250,000 miles so I changed my u joints also.
Used Neapco 2-0054HD u joint and Mobil 1 Synthetic Grease.

Greasable tend to fail once you pop the seal. They aren't technically "purge at all 4 caps" now if we're talking semi's you're supposed to grease til it comes out of the 4 caps evenly, if it doesn't come out of one cap then the joint is supposed to be considered faulty and replaced even if there isn't any slop... That's proper PM, never gets done that way tho lol I like greaseless just bc it has better seals to keep grease in and crud out, however all the grease I've seen used in them appears to be a moly type which I feel is what attributes to their failure. I'm a huge fan of red n tacky or similar. At the same time greaseless joints aren't always available for the vehicle. Aftermarket tends to favor grease able.
