new driveshaft with 1350 yoke- best lubricant?

Thanks to all for the input, fellas.



By slip joint, do you mean the end that slides onto the splines in the tail shaft of the transmission? I wasn't even worried about that end as it's inside the seal and gets bathed in ATF (for automatics, obviously), doesn't it?? With that idea rattling around in my non-mechanically inclined brain, I just coated the whole thing with transmission fluid inside and out and slid it right in. Should I reevaluate that procedure?
no , all good In front
