Freeway driving
Ok - the scoop here,
4 speed - NP205 - 31" tires - 86 suburban dana 44 in a 1970 stepside. Hubs unlocked - 2 high - 70MPH = no vibration. Hubs locked - 2 high - 70MPH = severe vibration. Hubs locked - 4 high - 70 MPH = very severe vibration. Hubs locked - 4 low - 10 MPH = no vibration. Transfer case shifter rattles all the time. Visually inspected all u-Joints - look good. Anyone got an idea on were to start? Thanks
