3. Broken or sagging springs.
4. Overloaded car.
Suspension Bottoms
1. Overloaded car.
2. Faulty shock absorbers.
3. Incorrect, broken or sagging springs.
"Dog" Tracking

2. Broken spring leaf.
3. Bent rear axle housing.
4. Frame or underbody alignment.
Steering Wheel Kick-Back (Power)
1. Air in system.
2. Worn or missing poppet valve (gear).
3. See "Too Much Play In Steering" for other possible
causes.
Steering Wheel Surges Or Jerks (Power)
1. Hydraulic system-Make pressure test with gage J
5176-1.
2. Sluggish flow control valve.
Vehicle Pulls To One Side (No Braking Action)
1. Front or rear brake dragging.
2. Off center belt in tire casing.
Wheel Tramp
1. Blister or bump on tire.
2. Improper shock absorber action
Excessive Or Uneven Tire Wear
I. Hard driving.
2. Overloaded car.
Scuffed Tires
1. Toe-in incorrect.
2. Excessive speed on turns.
3. Suspension arm bent or twisted.
Cupped Tires
I. Front shock absorbers defective.
2. Wheel bearing incorrectly adjusted or worn.
3. Excessive tire or wheel run-out.
4. Worn ball joint.
LINKAGE DIAGNOSIS
Excessive Play or Looseness in Steering System
2. Steering gear worm bearings loosely adjusted.
3. Excessive pitman shaft to ball nut lash in steering gear.
4. Worn intermediate rod or tie rod sockets.
Excessive Looseness in Tie Rod or Intermediate
Rod Pivots, or Excessive Vertical Lash in Idler
Support
1. Seal damage and leakage resulting in loss of lubricant,
corrosion and excessive wear.
Hard Steering (Excessive ~ f f o r t Required At
Steering Wheel)
I. Tight or frozen intermediate rod, tie rod or idler
socket.
2. Steering gear adjusted too tight.
MANUAL STEERING GEAR
DIAGNOSIS
Excessive Play or Looseness in Steering System
1. Worn upper ball joints.
2. Excessive pitman shaft to ball nut lash.
3. Worm bearings loosely adjusted.
4. Steering wheel loose on shaft; loose dtman arm, tie
rods, steering arms or steering linkage ball studs.
Rattle or Chuck in Steering Gear
1. Insufficient or improper lubricant in steering gear.
2. Pitman arm loose on shaft or steering gear mounting
bolt loose.
3. Loose or worn steering shaft bearing.
4. Excessive lash between ball nut and pitman shaft in
straight ahead position or worm thrust bearings adjusted too
loose.
NOTE: On turns, a slight rattle may occur due to the
increased lash between ball nut and pitman shaft as gear
moves off the center of "high point" position. This is
normal and lash must not be reduced to eliminate this
slight rattle.
POWER STEERING PUMP AND
GEAR DIAGNOSIS
Hissing Noise in Steering Gear
1. There is some noise in all power steering systems. One
of the most common is a hissing sound most evident at
standstill parking. There is no relationship between this noise
and performance of the steering. "Hiss" may be expected
when steering wheel is at end of travel or when slowly turning
at standstill. Do not replace valve unless "hiss" is extremely
objectionable. A replacement valve will also exhibit slight
noise and is not always a cure for the objection. Investigate
clearance around coupling rivets. Be sure steering shaft and
gear are aligned so flexible coupling rotates in a flat plane and
is not distorted as shaft rotates. Any metal-to-metal contacts
through flexible coupling will transmit valve "hiss" into
passenger compartment through the steering column.
1. Worn upper ball joints.
