The wife was driving my truck and hit black ice and went fishtailing at 65 mph but did not go in to the ditch. NowI have a violent vibration at low speeds, It stops about 35 mph. I have replaced all *****, rotors, pads, hubs, u joints, sway bushings, shocks, and rotated tires with no change.
I dont really feel the shake through the steering wheel. Tie rods seem to be good.

My vibration does not start up until the truck has been driven for 3-5 miles at least, basically to warm up what ever it is. The cv boots are not ripped, hard, or twisted. Splines look good. Rear end backlash is good. Do not know how to check front. New fluid all around. Any thoughts anyone..?

 

Can inside the cv go bad without clicking or have outside wear. when i engage 4x4 it almost feel like driving over a stump and loud clang when taking it out.
