A vibration started in the drive train at 55-60 MPH, hade all u joints changed and drive shaft balanced, centre drive shaft bearing running cool, all wheel bearings running cool, rear axel u bolts tight. Took it over the sunshine bridge , vibration is more noticable under lots of power in O. D. , going down hill kicked it into nutral and vibration subsided to total smooth, kept RPM up around 1800. I am hauling a 14000# 5th wheel back to Ont. Canada. Need a good transmission shop in the Tamapa , St Pete's area.
