    I just bought 35-spline outer axles for my D60, I have found that non-greaseable u-joints are stronger and I plan on using them on this project! What do you think? Should I use Greaseable or Non-greaseable? I was planning to use Spicers, what brand of u-joint do you use?

    You are correct that the non-greasalbe are stronger than the greasables...I would have to say go with the non-greasable and just plan on rebuilding them a little more often, esp. if you run mud and water a lot...

    They may be a little stronger...but the greasable at least you can maintain them better. I've found the 'sealed' non greasable U-joints usually aren't that sealed and dry up and fail faster. At least with greasable I can pump new grease in at regular intervals and especially after wheeling.

    I use CTMs U joints. I haven't had a problem with them yet. They're tough as a two dollar steak. A little on the expensive side. I woop the heck out of mine and haven't had a problem yet. I did have to get new 35 spline stubs two weeks ago. I am starting to think the CTMs are too strong. Yeah right!!

    I talked to a driveline specialist yesterday about this... i had to have a u=joint changed... he charges me 15 bucks to put in a neepco u-joint installed and the part for 15 bucks! the part lists at 15 he does it for 10 bucks... install is 5 bucks...
    Anyways, I asked about greasable and non greasable... He said they are weaker but the weakness you loose going with non greasable when your playing in the mud/water is worth the difference. You get one grain of sand in a u-joint cap.. it'll tear the needle bearings up in a matter of miles... if you can pump grease through them when you get off the trail, well it cleans out the u-joint much better!
    So when I buy u-joints I buy the greasable ones for my u-joints and solid for the front end... if I break a front axle u-joint... I can still drive home... and i need the extra strength.. but the drive shaft... i want to be able to flush out...

    I personally can't see any time that I would use a non greasable.
    if the pin hole grease passage is the make or break point for your ujoints it is time to step up to bigger stuff
    I dont like disposable parts

    I've got one application (that I know of) where I like non greasables - the funky double-cardan joint on some Fords. There's no way to get a grease gun on them without dropping the shaft, and it's the front shaft anyhow - the better quality sealed are the way to go there IMO.

    that is one where I would want a grease option
    CVs are $$$ so anything I can do to extend its life I will try
    greaseable CVs usually use a needle type nipple that can be reached with effort

    I had a brilliant idea on it of putting in a pipe plug in place of the zerk - I couldn't get anything on it to get the plug out though. Now I need to invent something like the self sealing top on a drug vial to grease them. I might even make a 30 or 40 cent profit/forums/images/icons/smile.gif

    I think the needle style nipple is as good as it is gonna get
    like the ones used on CTM caps

    You're probably right - I came up with the self sealer idea after looking at the little oiler cap thingies on my lawnmower - they don't seem to let anything past them, but I've never seen anywhere where you can just buy these fittings.
