ujoint tight Q
If you press the caps in a bit too much they can bind a little. I always tap them back a bit if they feel stiff. Not sure it would make and difference in longevity, but, it makes me feel better! What brand U-joint was installed? There's some real junk out there these days. I like the official Spicer ones and also the older Precisions for performance use. The original Mopar ones are good too.....probably made by one of the name brands.
