Solved 2008 Mercury Mountaineer with shaky driving on the highway.

Ok so this vehicle had a vibration at 75 mph. After checking tires it was obvious that it needed new tires. New tires were balanced and installed on vehicle. On the highway it still shakes at 65 mph now. The vehicle was placed on ramp stands and jack stands. By process of elimination the drive line has been replaced and both rear short shafts, or axles. Nothing has stopped the vibration. This is a 2wd 4.6 vehicle. Tires have been rotated around also and still no fix. Does anyone have any suggestions?

Welcome to this forum! Did you check the tie rod ends, universal joints, ball joints, rubber bushings, and the brake rotors?

Pull the driveshaft and see if it still vibrates.

Ok we have it figured out thanks for all the help. We actually got another vehicle with the same tires and rims and changed all four out. It drove smooth as could be. It’s not an off road vehicle but some how two front wheels were found to be bent. They are aluminum. Problem solved. Except now I need to figure out how to turn low tire sensor off.
