Somehow my front driveline is bent. I have not used the 4wd except a trip around the neighborhood (where I immediately noticed a shake). Maybe I just didn't notice when I took it in, but I would be surprised if the shop I paid would put new U-joints in a bent driveline. I did not replace the cardan joint at the same time (and probably should have). This driveline was also about 3/4" longer than the other one that was on the truck when I got it.
