Why would a 4x4 go into 4hi-4lo but when you start moving and give it a little gas the tires spin?
you could have a siezed front u joint replace it and the noise should go away.
Why might a car start shaking at 60 mph when there was no previous problem and no recent work The weather has been severely cold lately could that be the only problem?
generally no, the tire is the part of the car that makes the whole thing actially move allong the groun. however if it is a fwd car and the e-break is on, at low speeds thee rear tires could be not moving and the car is. During a panic stop from high speed without ABS brakes you can skid, 50...60 feet or more with the tires locked up and the car is moving
