Tire out of balance, low air pressure, broken or slipped belt in tire, or wheel mounted incorrectly. Remove both front wheels, inspect the tires for bulges, dips, or feathering, inflate to correct PSI, reinstall and torque in a criss cross pattern to proper torque. If you still have the problem have the tires checked for proper balance. You should always check the balance when rotating tires.
the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover
A bad bearing can cause can the front end of car to make a squeaking noise when turning steering wheel either direction. It can also be caused by bad suspension.
Change the polarity of either the field coils or the armature, not both and you will reverse rotation.
no because power steering is a hydrollic assist system
If you have rack and pinion steering, the steering gear will need replaced.
Could be bad joints in the steering shaft, could also be bad tie-rod ends.
Could be steering rack is worn and needs replacement
The problem with this concern could easily be the steering gear. The power steering pump is responsible for providing fluid pressure but the steering gear will provide steering assist with the fluid pressure depending on steering wheel input. with the front wheels suspended and the engine off with the pittman arm disconnected from the steering gear the wheels turned left to right by hand at the tires should turn with the same effort both ways. if not, the concern is within the suspension (ball joints) or steering someplace. If the steering effort is the same suspect a steering gear fault.
The power steering pump has probley quit working.
could be something with the steering or with the power steering pump.
Worn steering and suspension parts, this could be dangerous, have it checked by a trusted mechanic soon.
The power steering on a vehicle can be jammed due to a rack and pinion issue in the steering column. Another possible cause could be that the power steering fluid may be low and the power steering pump may be going out.
