F-150 Shakes

Suggest every once in a while to find a quiet place you can drive safely about 30 mph, with a cement wall located parallel to your drive, roll down windows, and listen for squeaking sounds from u-joints reflecting off that wall. That’s how my Ford truck exhibits early signs of rear driveshaft u-joint problem. Usually if I catch it early, all it needs is a lube. Lubing u-joints may not be possible on your truck however, but at least you’ll know you’ve got a problem developing.
