Steering Gear Mechanism

Question 1
Marks : +2 | -2
Pass Ratio : 100%
The tilting of the front wheels away from the vertical is called
caster
camber
toe-in
toe-out
Explanation:
The angle between the vertical line from the centre point of the tyre and the central line of the tyre is known as the camber angle.
Question 2
Marks : +2 | -2
Pass Ratio : 100%
Wheel wobbles occur due to
wheel out of balance
worn joints in assembly
loose wheel bearing.
bent steering knuckle
Explanation:
It is caused due to following reasons
Question 3
Marks : +2 | -2
Pass Ratio : 100%
Erratic steering is caused due to
worn out brake lining
brake lining choked with oil
brake lining choked with brake fluid.
insufficient lubricant
Explanation:
It is caused due to following reasons
Question 4

Pass Ratio : 100%
Wheel wobbling can be fixed by
adjusting and repairing it
balancing wheels
adjusting bearings.
replacing brake lining
Explanation:
It can be fixed by the following remedies
Question 5
Marks : +2 | -2
Pass Ratio : 100%
The only service that a steering linkage normally requires is
tie-rod adjustment
lubrication
ball-joint replacement
none of the mentioned
Explanation:
In the linkage-type power steering system, the power cylinder is not a part of the steering system. Instead, the power cylinder is fitted into the steering linkage.
Question 6
Marks : +2 | -2
Pass Ratio : 100%
Too much toe-in will be noticed by
excessive tyre wear because of taking corners
steering wander
feathering of tyres
light steering
Explanation:
The toe-in ensures parallel rolling of the front wheels. It stabalises steering and prevents side slipping and excessive wear of the tyres.
Question 7
Marks : +2 | -2
Pass Ratio : 100%
In the steering gear, a gear sector or toothed roller is meshed with a
ball bearing
roller bearing
worm
steering wheel
Explanation:
A rotary valve power steering gear for the integral system uses recirculating ball-type worm and wheel steering gear.
Question 8
Marks : +2 | -2
Pass Ratio : 100%
Caster action on the front wheels of a vehicle will
make it easier for the driver to take corners
help reduce the load on the king-pins
automatically achieve the straight wheel position
none of the mentioned
Explanation:
Negative caster produces directional stability to the vehicle keeping the wheel position straight.
Question 9
Marks : +2 | -2
Pass Ratio : 100%
Hard steering is a result of
incorrect lubricant
broken or bent steering arms or knuckles
too tight spherical ball joints
insufficient lubricant
Explanation:
Hard steering is caused because of the following reasons:
Question 10
Marks : +2 | -2
Pass Ratio : 100%
Excessive play or looseness in the steering system is caused by
very loose steering linkage
worn out steering linkage
too loose front wheel bearings
worn out front wheel bearings
Explanation:
Excessive play or looseness in the steering system is the result of
