    For the driveshafts, I use the $8 ones from Advance Auto. Lube them before and after an offroad run.

    There is a company called Rockford that makes u joints. I picked up a set heavy duty ones that dont have grease nips. Not sure if this is a good idea or not. They have a better seal than the reg. duty ones tho. They were 20 bucks (CDN) each. Opinions?

    Some say they are stronger since the cross isn't drilled.

    But, if you play in water, the seal may be better but it's not perfect. Water will get in a non-greaseable ujoint eventually, and eventually play havoc with the needle bearings.
    For my kind of wheelin... moderately difficult, plenty of water... I don't put an undue amount of stress on my ujoints, so I prefer the greaseable. I can push all of the water out when I get home with two pumps of the grease gun on each zirk.
    That's my two cents... ;)

    I agree with Lynn. At lunch today, I bought 2 new ujoints for my rear driveshaft. The guy came to the counter with 2 of the "BruteForce" units - which I know don't have the grease fitting. They are actually more expensive b/c they are "stronger". I asked if he had the greasable joints and he said yes. The other guy working behind the counter actually commented that he used the cheaper, greasable ones too. He went on to say that, in his opinion, the non-greasable might be stronger sitting in the box, but once they were put into use and it heated up from a lack of lube - the BruteForce joint would fail before the greasable one.

    Sorta like the Ford vs. Chevy argument. Everyone has an opinion. I like the ones with a zerk fitting...

    Warn did multiple tests with special equipment that twists the u-joints and shafts on different u-joints and different axle alloys when they started building the alloy axles. Spicer held up the best. The greasable ones and non greasable held up fairly closely the same suprisingly. The other brands weren't really even close to the # of lbs./inch of torque it took to break them.

    Well, I also use the cheaper shaft joints for one very good reason. Under heavy load off-road I prefer to change a (broken) U-joint to a yoke. And as long as you keep them lubricated they will treat you well.
