Vehicle recall defect – A Design Deficiency Exists In The Air Dryer Piping In The Area Of The Pressure Relief Valve And Compressor Governor Control Link. Moisture Is Passed And Builds Up In This Relief Valve And Control Line. In Freezing Ambient Temperatures, This Moisture May Freeze, Allowing The Chassis Air System Pressure To Exceed 150 Psi. Excessive Air System Pressure Can Cause Separation Of Air Piping ConneCTIons And Air System Valve Failure.
Vehicle recall defect – The Pitman Arm, A Lever That Transmits Turning Movements From The Steering Gear To The Steering Linkage, May Loosen Or Break At Its ConneCTIon To The Steering Linkage. The Failure Can Prevent Turning Attempts From Having Any Effect. The Defect Is Caused By Incorrect Assembly Of The Ball StUD ConneCTIon In The Pitman Arm.

Vehicle recall defect – The Spring Seat Plate, Located Between The Axle Housing And The Suspension Springs, May Deform Due To Spring Bending. As A Result, The ClaMPIng Force In The Assembly May Be Reduced. Loss Of ClaMPIng Force Could Cause Spring Failure And The Axle Will Dislocate. Also, The Tire Could Come Into Contact With The Spring.
Vehicle recall defect – The Flange Head Pinch Bolts Used In The Yokes Of The Steering Shaft Assemblies May Have Been Overstressed Due To The Bolts Not Being Tightened To Specifications. As A Result, The Pinch Bolts Could Break While In Service.
Vehicle recall defect – The Pitman Arm Retaining Nut May Not Have Been Torqued To Manufacturer Specifications. This Could Result In Inadequate Retention Of The Nut At The Output Shaft, Allowing The Pitman Arm To Become Loose.
Vehicle recall defect – In The Event Of Turbocharger Compressor Wheel Failure, One Or More Of The Four Capscrews That Hold The Turbocharger Together May Be Struck By Parts Of The Compressor Wheel, Resulting In The Capscrews Being Damaged. If These Capscrews Are Damaged To The Point That They Allow The Compressor Back Plate To Dislocate From The Turbocharger Bearing Housing, Engine Lubricating Oil May Be Allowed To Escape Under Pressure, ContActing The Engine Exhaust Manifold SeCTIons Or Turbocharger Turbine Housing.
