Engine vibration at 1500-1600 rpm?

[davis3903]

all vibrations are gone, none what so ever. sticky ujoint (going out) and bad carrier bearing. i actually ended up dealing with a guy in san antonio. he explained that even if you get the ujoints from the dealer. they do not have the proper shims to center the ujoint. it takes a bit more time and the trouble is well worth it. they also can replace the yokes with quick change yokes so you can change ujoints in the field if need. old yokes off and new on and balanced. drive shaft specialist in san antonio texas. good guy there. brent crownover should have had this done when i bought the truck.
