Question on Serviceability of Drive Shaft Componen

[TANGARAY]

I am replacing the U-Joints on my '76 B. Old U-joints came out OK with press and tapping. Reasonable amount of effort needed but did not have to go gorilla. After cleaning and rust removal on the bores of the Yoke/Sleeve (splined joint on tranny end) with a Dremel E-Z Lock fine abrasive flap wheel, the new U-joint has a slip fit in the Yoke/Sleeve. When properly aligned, new cup will slide in. Didn't detect any slop. The other pieces (drive shaft, yoke/flanges) seem to have a press fit. I have not assembled yet as parts are etch/primed and are ready for prime and paint. My questions:
1. Is anything less than a light press/press fit of U-joint into flanges going to cause troubles? Vibration? Wear? Failure?
2. Should I just replace Yoke/Sleeve with new?
3. All mating pieces were marked prior to disassembly. Would introducing new part(s) couse issues with balance?
4. If Yoke/Sleeve is serviceable, should I assemble U-joint to yoke with green Loctite?

Thanks for your replies!

Paul, you can take a small punch at a 45 degree angle and lightly tap the surface the cups ride on in at least 4 places around and this will lock the cup in place. It's called peening. Take a small hammer and knock the top of the yokes to open them back up, they get out of alinement by the pressing and hammering. After installing the new parts all bearings should turn freely. A nice tight fit is not a good thing.

Thanks. I hadn't thought of peening, but that is a good idea.
