greasing u joints
I dont know much about drive shafts/u joints but I do know that my front u joint needs some grease, it is squeaking under acceleration in 4x4. Does any one have a link with pics or able to explain exactly where/what to grease and what type of grease? I mean is there a grease zert some where to look for? How do I tell if the u joint is shot and should just be replaced?
Also how is the front drive shaft removed? I'm looking at a set of headers and in the instructions it says to remove the front drive shaft. Thanks guys.

On the axle u-joints if you cant find the grease zerks they are probably the greaseless type or there is a little plug/bolt looking thing screwed into the end of one of the caps and you remove that and temporarily install a grease zerk the put the plug back. You dont leave the zerk in since there isnt enough room for it. One way to tell if the u-joint is shot is to have the hubs locked and t-case in neutral and safely jack up the truck tire and rotate the wheel back and forth. If the u-joint looks tight then it should be ok but if the u-joint goes clunk-clunk then replace it.
I dont know why you need to remove the front drive shaft for headers but you just unbolt the little u-joint retainers and remove the drive shaft. Be sure you dont drop the u-joint cups cause the little needle bearing will go all over.

Alright I'll just order a new one and get my bro in law to help me put it in. On summit racing their all less than $20. When it comes to ordering the new one, is there anything I need to know? Are the Spicer u joints the best? Thanks for all the good ideas.

If I do end up letting the shop do it, how many hours should he charge to change out that front u joint?

If ya replace the axle joints put in ones with a Zerk that Has an inverted nipple (watch the parts counter girl blush when ya ask for that). Than get a nipple adapter to fit on yer grease gun. These also work better on the double u joint on most front drive shafts. always get greaseable u joints. Most shops and Stealer's will put in the non greaseable ones cuz they are cheaper and garrenty that you will be back soon.

I've got a lot of non greasable joints in my time and I have never seen a solid one. I have drilled out the ones without and taped them for a Zerk. If there is solid ones out there for these years of tuck than I have never seen them. They are hollow and filled with grease when assembled. I can't imagine one with no lubricant lasting very long no matter what it was made out of.

The original U-joints on my '75 F150 had -no-zerks and outlasted the engine and "only showed any sign of wear" (according to the drive shaft guy:) "is because the carrier bearing went bad first". YMMV
An out of balance drive shaft and other vibration will kick-the-crap out of the U-joints in no time. :/
Yeah, I'm a "greezzer" and I know that grease only-slows-down whatever wear is going to happen anyway.

If you end up dropping the driveshaft yourself, use chalk or a crayon to mark the shaft and yoke so they go back together the same way they came apart. You can end up with a vibration if not.
