91 Toyota Pickup Speedometer
When I drive at about 40 or 50 km/h and faster the cluster starts making a vibrating/whining/screaming
noise. The noise cuts in and out on the highway and eventually goes away. also my speedo shows the car
running at a ratio of .1 faster than the car is moving but i'm guessing that's a wheel/tire size thing. At high
speeds the needle is jumpy. What is happening and how do i fix it? Thanks!
