Hello all,

I have a 02 Escape XLS (V6) and I just got four new tires and alignment done. But the car still vibrates a bit on the highway, especially when the speed is over 120KM/h.

secondly, when drive on bumpy roads, the car seems to shake a bit, feels more bumpy than it should, and I can sort of feel that the front tires are off the ground slightly. Is this normal?

Thirdly, when have the 4X4 option on, I get stuck when backing out the car with an angel (like 45 degree), it is sort of like the wheels (at the rear or the front, not sure) are locked. Same thing does not happen when I turn off the 4X4 option.

I have done some research, some people are suggesting CV joint problem, any advices will be appreciated.

Hi JD64,

thank you for your quick reply. I appreciate your point about point #3.

In terms of the vibration, it almost feels like that I am losing a bit control of the car as I can feel the steering wheel is shaking, this only happens if the speed is above 110km/h and gets worse as I accerelate.

For point#2, I have checked my tire pressures, they are all set at 30psi.
