OE-Style Fitment and Construction

This InMotion wheel bearing and hub assembly is manufactured with high-precision processes and strict quality-control standards to match the original application.

Common Reasons to Replace

• Rear wheel bearing noise such as humming, growling, or rumbling
• Excessive wheel play or looseness at the hub
• ABS warning light caused by a failed hub sensor
• Uneven wheel rotation or vibration from hub wear
• Corrosion or damage at the rear hub mounting surface

Installation Notes

Confirm rear fitment on the vehicle before installation and verify the 5-stud, 114.3 mm bolt pattern matches the original hub. Inspect the knuckle, axle area, and brake components for wear before assembly, and transfer only the components required by the vehicle service procedure. After installation, clear ABS fault codes if present and road test to confirm proper operation.
