A loud knocking noise in the motor of a car at high speeds is most likely the engine. There could be another issue with the transmission if the knocking only happens at high speeds.
Could be out of balance Tire may be worn and need replacement Could be a bent wheel
The steering stabilizer helps prevent your car from wandering all over the road at high speeds. The wobble on your car is typically from the excessive shaft play in the steering box, so its mainly a precaution.
Bad tire, bad wheel, bad cv shaft.......
== == As the car speeds up the unbalanced wheels start to wobble. The force of the wobble is transferred to the cars body through the steering mechanism. You would feel the shaking first in the steering wheel. It becomes more pronounced as you pick up speed. == == * Front end need's religning, bad tires or tie-rods. * Tires are low in air.
A car that is jerking at high speeds probably needs a tune-up. Barring any major mechanical issue, this will solve the problem.
The front wheels of a car can wobble because the car's suspension is not in proper alignment. The wheels may also wobble if the rim is bent or if the tire is improperly installed
Probably a matter of where the engine's power band is set out, or you may simply be bogging the engine down at lower speeds. Try downshifting and keeping your RPMs up a little.

If you hit it at high speeds in a car, it is likely to be the death of you.

Definately avoid driving at high speeds, and get it in to see a mechanic to see what is going on. It might be nothing, but it could be something serious.
