Do the constant velocity u-joints on my extended cab need lubed. I heard ,one time the there is a special tool to attach to the grease gun to lube them. I see no mention in the owners manual, and I just don't have a service manual yet..I never worked with them before. Andy
No, they're sealed, until the boot breaks anyway.
If you are talking about the one by front axle to drive the front wheels on a 4WD, they a sealed and do not need relubing unless the boot ruptures.
Perhaps you are thinking of the double carden u-joint that came on "some" S-10 rear driveshafts. I don't think they are servicable in that year. It used to be that you could use a needle tip on your grease gun to lube the ball and socket.

I'm sorry ,gentlemen...I should have made myself clear, they are on the extended cab model, on the driveshaft, back to the differential. Ian, thank you, that is what I was referring too. I will just leave them alone, I just have 40,000 miles on the truck. Andy
If you aer talking about regular drive shaft joints, most factory joints do not have grease fittings on them these days.
