Front end vibrates while accelerating after 65 mph.

Possible weak engine mounts or inboard axle joint(s). MOST common suspects , in my book.

Replace the complete suspension/steering components i garantee driver/passenger rear and front lower control arm bushing(s) are failing causing a sifting motion as well as excessive vibration in the steering columnn at anything above 65. luckily eBay has a full 12pc front and rear suspension kit for $131.00 take a look ski. Might not kill ya to replace the engine mounts and months of all major engine compenent s
