Possible Steering Problems & Causes
Normal Noises:
-You or the driver may hear a hissing noise from the control valve when it is actuated during a steering maneuver.
-You or the driver may hear a noise as fluid bypasses through the poppets at full turn.
-You or the driver may hear a noise from the system relief valve when it is required to actuate.
-You or the driver may hear pump growl from some types of power steering pumps
Abnormal Noises:
– If the power steering pump is belt driven, a squealing noise may indicate that the belts should be tightened or replaced.
– A clicking noise heard during a turn, or when changing directions, may indicate that some component is loose and shifting under load.
– A change in the normal noise of the pump may indicate a faulty valve or wear in the pump.
– A change in the normal noise of the pump may be due to kinked or plugged hoses.
– Because of plugged filter there may be a whining from the pump.
– Improper adjustment of gear box will result in abnormal noise from pump.
Drift or Wander:
– Tire pressure incorrect or unequal pressure left side to right side.
– Components in steering linkage loose or worn (steering wheel to road wheel).
– Wheel bearings improperly adjusted or worn.
– Front end alignment out of specification.
– Read end alignment out of specification.
No Recovery:
– Tire pressure low.
– Front end components binding.
– Front end alignment incorrect.
– Tight front axle king pins.
– Dry fifth wheel or poor finish on fifth wheel or trailer plate.
– Steering column binding.
– Pump flow insufficient.
– Steering gear improperly adjusted.
– Steering gear control valve sleeve sticking.
Shimmy:
– Badly worn or unevenly worn tires.
– Improperly mounted tire or wheel.
– Wheel bearing improperly adjusted or worn.
– Components in steering linkage loose or worn.
– Wheels or brake drums out of balance.
– Front end alignment incorrect.
– Air in the hydraulic system.
– Free play in steering gear.
Oversteering or Darting:
– Dry fifth wheel or poor finish on the fifth wheel or trailer plate.
– Front end components binding or loose.
– Steering column binding.
– Steering gear improperly adjusted.
– Steering gear control valve sleeve sticking.
– Rear axle mounts (rear steer).
External Oil Leakage:
– Finding the location of leak may be difficult, since oil may run away from leak source, the fittings, hoses, pump, or gear to a low point on the gear or chassis.
– A leak from the vent plug at the side cover indicates failure of the sector shaft oil seal inside the side cover.
High Steering Effort in One Direction:
– Unequal tire pressure.
– Vehicle overload.
– Inadequate hydraulic system pressure.
– Excessive internal leakage in one direction of turn only (of gear box) (verify with internal leakage test).
– Valve misadjusted.
High Steering Effort in Both Directions:
– Low tire pressure.
– Vehicle overload.
– Low hydraulic fluid level.
– Incorrect hydraulic fluid.
– Low pressure or flow from pump.
– Components of steering system binding.
– Restriction in return line, or line too small in diameter.
– Excessive internal leakage (verify with internal leakage test).
– Oversize tires (check manufacturer’s specifications).
– Loose pump drive belt.
– Front end needs lubrication.
– Improper front end alignment.
– Air in hydraulic system.
Lost Motion (LASH) at the Steering Wheel:
– Steering wheel loose on the shaft.
– Loose connection between the steering gear, intermediate column, and steering column.
– Steering gear loose on frame.
– Pitman arm loose on output shaft.
– Components in steering linkage loose or worn.
– Steering gear improperly adjusted or defective.
Excessive Heat (150°F [65.6°C]):
– Excessive pump flow.
– Vehicle overloaded.
– Undersized replacement hose or line.
– Restricted hose or line that is kinked or severely bent or internally blocked.
– Restricted recentering of gear valve caused by column bind or side load on the input shaft.
– Poppet not adjusted properly (only for gears equipped with poppets).
– Prolonged stationary vehicle operation.
Cast and Stamp Numbers
Cast Numbers: These numbers are made in the housing during the casting process. These numbers can be depression or can be raised.
Casting numbers can ONLY identify the series of gear box. In some cases (Saginaw for example) they are one of the only forms of identification. But in most cases the casting number does not help to identify the gear box.
Stamp Numbers: When a number or letter stamp and a hammer are used to make an impression in the cast iron or aluminum housing, or on a metal tag pop riveted or bolted to the housing or cover. The stamp number usually starts with the same numbers as the series number.
Example stamp #TAS65027 series #TAS65
On many steering gears the only way to properly identify them is with the stamp number. This number is the part number assigned by the manufacturer.
