I have to change the rear-end pinion seal. Do you think it would be prudent to change the U-Joints in the drive shaft while I got it out?

They are showing a little wear and tear.

If so what brand of U-Joint? Spicer... Brute Force ... or like a regular Eckler's House Brand?

without a doubt. Sometimes we all get carried away with the YOU MIGHT AS WELL thing, but snce it's apart and they are relatively cheap, why not. Think about how expensive it would be for one of them to let go on the side of a road one night. For the cost of a tow you can replace all of the ujoints.

You can pull the caps off the U joints and inspect them and then decide what to do.

I use the solid Spicer u-joints. If there is any wear at all in the joints, replace them while it's out.

Make sure you mark where the nut is tightened to on the pinion and only tighten back to this point. Tightening it beyond where it is setup now can cause pinion bearing failure from loss of clearance.

And mark the front drive shaft yoke so it goes on in the same position it came off.

The solid Spicer U=joints are the strong ones, but for your application, other than the need to grease them, just about any of the USA made joints will work. (The Spicer joints for my half shafts are about $17 each.)
