Vibration in Gear,

05 blazer. Loud sound putting in R or D. Vibration. not as bad when come to a stop but its still there. One mechanic said water pump. Removed belt and vibration stopped. New motor mounts. One mechanic said slight miss. Can't keep replacing parts hoping to find the right fix..
211,000 miles. Replaced water pump 11/23. not sure if fan clutch was. Heading to mechanic who replaced pump. Totally frustrated.

When you had the belt off did you grab any of the accessory driveshafts to see if they were loose?

Does the vibration frequency match the engine speed or wheel/transmission output speed?

vibration frequency seems to be constant. . Speed doesn't change
