On certain vehicles, the nut on the bolt which connects the steering gear to the steering coupling may not be tightened correctly. Loosening of the nut could result in a slipping of the connection over time, increasing the risk of a crash.
Safety Risk
No risk description available.
Remedy
Dealer will inspect the vehicles and tighten the nut if necessary.
On certain vehicles, the intermediate steering shaft yoke may not have been properly seated onto the steering gear input shaft during installation. In this condition, the yoke may not be properly clamped to the input shaft. This may result in separation of the yoke from the steering gear input shaft and a loss of steering control, potentially resulting in a vehicle crash.
Safety Risk
No risk description available.
Remedy
Dealer will inspect the steering intermediate shaft yoke. If the yoke is not fully seated and the bolt groove and spline is visible, the intermediate shaft and bolt will be replaced as well as the bolt at the steering column connection.
On certain ML320, ML350, ML430, ML500 and ML55, the hose clamp used to secure the power steering fluid cooling hose to the power steering cooler may not provide sufficient clamping force for this connection. The loss of power steering fluid may result in diminished power steering over time and may ultimately damage the power steering pump.
Safety Risk
No risk description available.
Remedy
Dealer will replace the power steering hose clamp.
On certain vehicles, the power steering high pressure hose may contact the left exhaust manifold. If this were to happen, the hose could burn through and cause a progressive loss of hydraulic fluid and power steering assistance.
SOME PASSENGER VEHICLES HAVE A CONDITION IN WHICH THE INTERMEDIATE STEERING SHAFT BOLT MAY BE LOOSE.
Safety Risk
AN IMPROPERLY TIGHTENED BOLT COULD LOOSEN, RESULTING IN SEPARATION OF THE UPPER AND LOWER STEERING SHAFTS CAUSING A LOSS OF VEHICLE CONTROL. IF THIS HAPPENS WHILE THE VEHICLE IS MOVING, A CRASH COULD RESULT WITHOUT PRIOR WARNING.
Remedy
DEALERS WILL INSPECT FOR THE PRESENCE OF THE INTERMEDIATE STEERING SHAFT BOLT AND ENSURE THAT IT IS TIGHTENED TO THE PROPER SPECIFICATION. OWNER NOTIFICATION BEGAN MARCH 20, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CADILLAC AT 1-800-458-8006.
On certain vehicles, the intermediate steering shaft bolt may not be torqued to the proper specification. An under-torqued bolt could loose, resulting in a separation of the upper and lower steering shafts and loss of vehicle control. If this happens while the vehicle is moving, a crash could result without prior warning.
Safety Risk
No risk description available.
Remedy
Dealers will torque the intermediate steering shaft bolt to the proper specifications.
On certain vehicles, the power steering gear could have an improperly formed spacer clip, which can dislodge within the steering gear. If this occurs, the dislodged clip may cause increased steering effort.
IN SOME OF THESE SPORT UTILITY VEHICLES, THE DIAMETER OF THE STEERING COLUMN INTERMEDIATE SHAFT IS TOO SMALL.
Safety Risk
THIS CONDITION COULD ALLOW THE INTERMEDIATE SHAFT TO SPIN INSIDE THE STEERING COLUMN COUPLING, RESULTING IN LOSS OF STEERING CONTROL OF THE VEHICLE. IF THIS WERE TO HAPPEN WHILE THE VEHICLE IS MOVING, A CRASH COULD RESULTING WITHOUT PRIOR WARNING.
Remedy
DEALERS WILL INSPECT, AND REPLACE IF NECESSARY, THE STEERING COLUMN INTERMEDIATE SHAFT. OWNERS WERE NOTIFIED BY TELEPHONE ON FEBRUARY 7, 2003, WITH A FOLLOW-UP LETTER ON FEBRUARY 11, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT BUICK AT 1-800-521-7300 OR PONTIAC AT 1-800-762-2737.
On certain vehicles, the steering column intermediate shaft is undersized, which could allow the intermediate shaft to spin inside the steering column coupling resulting in loss of directional control of the vehicle. If this were to happen while the vehicle is moving, a crash could result without prior warning.
Safety Risk
No risk description available.
Remedy
Dealer will inspect, and replace if necessary, the steering column intermediate shaft.
On certain vehicles, the front lower control arm ball joints could experience a loss of lubrication, which could eventually allow the knuckle to separate from the lower control arm while the vehicle is in operation. A ball joint separation could possibly result in a loss of directional control.
Safety Risk
No risk description available.
Remedy
Dealer will replace both front lower control arm ball joints.
On certain 2500 and 3500 series vans, the nut attaching the pitman arm to the steering linkage may not be torqued to specification, which could lead to a possible separation. A separation could result in loss of vehicle control, and a crash could occur without prior warning.
Safety Risk
No risk description available.
Remedy
Dealer will torque the nut to proper specifications.
On certain vehicles, the right-hand tie rod end nut may not have been torqued to specification and could loosen, resulting in separation of the tie rod. This could cause unexpected steering input and could cause a crash without prior warning.
On certain vehicles, the lower pinion bearings retainer tabs were not crimped properly. These and some other retainers used in vehicles assembled between January 1, 1996 and October 31, 1997 may fail and permit the ball bearings to escape. If the problem were to occur, the driver would have to exert more effort to turn the steering wheel.
Safety Risk
No risk description available.
Remedy
Dealers are to inspect the condition of the lower bearing, and replace the lower pinion bearing or the rack and pinion steering gear assembly, if necessary.
On certain motorcycles, due to a manufacturing fault in the lower triple clamp, the bottom triple tree of the front suspension may separate from the steering stem resulting in a loss of control and risk of injury.
Safety Risk
No risk description available.
Remedy
Dealer will inspect and replace the lower triple clamp as necessary.
On certain heavy-duty class 8, VHD axle back vehicles. The telescoping steering shaft in some driving situations could bottom out and side load the steering gear input shaft whenever the adjustable steering column is adjusted to the lower position. Over time, this condition could damage the steering gear input shaft resulting in loss of vehicle control and a vehicle crash.
Safety Risk
No risk description available.
Remedy
dealers will install a re-designed steering shaft, which will not bottom out during vehicle operation regardless of where the adjustable steering column is positioned.
On certain passenger vehicles the lower steering column shaft coupling may have been installed onto the input shaft of the steering rack with too much clearance between the bottom of the coupling and the steering rack input shaft housing. As a result, the lower steering column shaft coupling could separate from the input shaft of the steering rack, increasing the risk of a crash.
Safety Risk
No risk description available.
Remedy
Dealers will adjust, if necessary, the clearance between the lower steering column shaft coupling and the steering rack input shaft housing, and re-tighten the coupling locking bolt.
Certain passenger vehicles were built with missing or under-torqued steering gear attachment bolts. If a bolt is missing, the driver may notice uneven steering response or unusual noises during turns. If the left bolt is missing and the right mounting strap fails, steering control is lost and a vehicle crash could result.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the vehicles for presence and proper torque of both steering gear bolts
Certain passenger vehicles. The steering knuckle castings may have been contaminated during the casting process. These knuckles can break resulting in possible loss of steering control.
Safety Risk
No risk description available.
Remedy
dealers will inspect the steering knuckle for the casting bunch number. If the knuckle belongs to the defective batch, the steering knuckle will be replaced
The steer axle tie rod ball-socket assembly ball stud may separate from the socket due to premature wear. If this event occurs, there will be no steering control to the right steer axle with the potential for a vehicle crash.
Safety Risk
No risk description available.
Remedy
suspect tie rod ball-socket assemblies will be inspected and replaced as required by dealers.
