bad vibrations
My '74 k/20 has a bad hopping motion at about 40-45 mph when slowing down. I have a 6'lift and stock wheels or winter on but had to use a driveshaft from a 71-72 k/20 for length. I goes away when I get on the gas and comes back when I get on the brakes. It feels like the whole truck is bouncing up and down. any help appreciated THanks.
