    I dont think there spicer I believe there neapco......
    I too like good u-joints...
    I beat the piss outta my ones from spicer and ones from napa... I couldnt find complaints about either... I heatedall the grease out of the napa one on a trail ride and (from bad driveshaft angle) and it still held together... was looser thann crap but didnt let go... so I was impressed by both the napa's and the spicers!

    Personally I like the sealed ones better...I dont mud often, the ones on there have probably never seen mud, and its a PITA to get to the zerks on mine, so I just say f*** it and leave them...i had a greasable and a seald one on the rear driveshaft, and the greasable one already froze up after about 6 months, sealed one still going strong...replaced the greasable one with another cause the parts store was out of the sealed ones...this was August. Went to grease it in late October and grease only came out of one cap. This is why i like the sealed ones.

    I run the non-greasable spicers. they are proven to be alot stronger and they are better sealed than the greasable kind, so they keep the water out. just my 2 cents. I have had mine for about 2 years now with no problems.

    <font color="green"> I have to say sealed as well. I have run them for 2-3 years and the grease is still good when I take them apart to check them. My theory is that the greasables have seals that are designed to let grease get out when you grease them, so they are more likely to let other stuff in. The non greasables have a much tighter seal on them so nothing is going to get in there in the first place. </font color>

    Well, I have ran the NAPA ones up here for years. They are made by Verdic... 13.00 each and greasable. I was burnin thru them at a rate of about 1 every 3 months. I grease them before and after every mud trip, and before every trip with no mud. Didnt matter, they would pack in around the 3 month mark. Finally I got fed up and tried a non-greasable type made by Rockford. They are called extreme duty, and run about 22.00 with a lifetime warranty. The ones I put in have been there for going on 8 months now. I will never put a POS greaseable in my truck ever again. Like was said on one other reply, they let the grease out when you pump it in, and it definately lets it out under normal driving, and totally lets water and dirt in. My experiences....

    every moving part has to be lubed.
    if you are killing u joints in short time you have a problem somewhere, i would guess buying off shore jobber junk parts.
    if you grease them you displace any contaminants out with the old grease.
    I have never seen a ujoint spit all its lube out within a normal service interval
    I have seen the condition of the so called 'sealed' non serviceables, rusted needle bearings.

    Well, you explain it then. If there is a problem, it would be a problem with the sealed ones as well. More than double the life out of them, Ill take it. You are from Canada too, they are NAPAs #1 brand Verdic. I cant argue against results tho.

    $13 vs. $22
    You USUALLY get what you pay for.
    Also the type of grease also plays a role. If you are pumping in grease that is breaking down, your u-joint will wear out faster. Most sealed units, use a "high pressure/high temp" grease.
    All things being equal, if you are "wearing out" u-joints (not breaking the crosses), then a greasable one (that is properly greased using a hiqh quality grease and maintained) WILL last longer than a non greasable one.
    If you do not like doing the maintainence, get a sealed one, as they are designed to put up with a higher degree of grease-neglect.

    I just put a 14-bolt in the rear of my 1990 Suburban that has 159,000 miles on the clock. It wasn't lifted in its previous life, but I was still surprised to find the factory original, non-greaseable u-joints in the driveshaft, complete with the injected plastic bearing cup retainers! /forums/images/graemlins/shocked.gif
