88984506 GM Ball bearing

What is this part?

The GM ball bearing 88984506 is a genuine OEM rotating component designed to support loads while allowing smooth, low-friction rotation.

What does it do?

This OEM ball bearing uses hardened steel balls and races to reduce friction between moving parts while supporting radial loads and moderate axial loads. Ball bearings are widely used in engines, electric motors, alternators, transmissions, wheel assemblies, and auxiliary components. A genuine GM ball bearing is manufactured to factory specifications, ensuring precise tolerances, quiet operation, high rotational speed capability, and long service life.

When to replace

The GM ball bearing 88984506 should be replaced if there are whining, grinding, or rattling noises, vibration, excessive play, overheating, or visible damage to the bearing surfaces. Worn bearings can increase friction and cause failure of surrounding components. Installing a genuine OEM ball bearing restores smooth rotation and mechanical reliability.

Compatibility

The genuine GM ball bearing 88984506 is compatible with selected GM vehicles or assemblies. Compatibility depends on bearing type, inner and outer diameter, width, load rating, application location, and model year. Always verify the part number 88984506 and bearing specifications before purchase to ensure correct fitment.

Installation: DIY or service?

Installation of the genuine OEM GM ball bearing 88984506 is not recommended as a DIY task unless the installer has bearing service experience and proper tools. Correct installation requires precise seating, proper lubrication (if applicable), and sometimes preload adjustment. Professional installation ensures quiet operation, correct load distribution, and long-term durability.
