Models equipped with ABS feature ABS sensor rings on the outer CV Joints. Inspection for chipped or missing teeth on these rings is essential. If necessary, the sensor ring should be replaced.

At the rear of the vehicle, assess suspension arm bushings for deterioration. Inspect drive axle boots, especially the outer CV boot, for tears, cracks, and loose clamps. It's also a good practice to wash drive axle boots to prevent premature deterioration caused by oil and grease. Replace any boots that show evidence of cracks, leaking lubricant, or damage.

During the inspection phase, old grease is removed from the outer race and the tripod bearing assembly. Each section of the tripod assembly is carefully disassembled and cleaned with solvent. The rollers, tripod, bearings, and outer race are inspected for scoring, pitting, or abnormal wear. If any issues are found, it may necessitate the replacement of the inner CV joint.

To assess the steering system components, start by gently rocking the steering wheel back and forth to detect excessive freeplay. Excessive freeplay could indicate issues with front wheel bearings, steering shaft universal joint, lower arm ball joint, or steering gear. Additionally, look for symptoms like body movement over rough roads, swaying around corners, and binding during steering wheel turns, which may suggest problems with steering and suspension components.
