U joints for driveshaft.

[hsracer]

Need to replace u joints on driveshaft. What's the best one to use. With grease fitting or no grease fitting.

[dangerdann]

We always put non greaseable spicer in ours. They are stronger and are smoother due to thrust washers inside the caps.

My DS guy always uses Spicer w/Zerks on the non thrust side to prevent breakage.

We've used both greasable and non and never had an issue with either but, like dangerdann and lizard said, always Spicer. U joints are not a place to save a buck or two.

Spicer non great able here just make sure ur not over tightening ur u bolts

[fastford]

one thing, spicer makes a standard and a heavy duty, the heavy duty has smaller needle bearings and are way stronger , this is what i use , as much movement as these drive lines have , they will hold up way longer.

Spicer, non greaseable +1 on the HD. Greaseable are hollow! Greaseable fine and preferred in a crate car. Replace every season for a weekly racer. Monitor the rear joint for any play at all, especially if running a lot of LR drop.
