What happens when pinion bearing fails?

A whirring noise when a vehicle accelerates is the signature symptom of a pinion bearing that is bad or is about to go break. The whirring noise will come and go at various speeds. The more worn the pinion bearings are, the more pronounced the whirring sound becomes.

Clunking sound every few feet: Such a sound at fairly regular intervals could be a sign of a broke ring gear or pinion gear. Howl or whine while driving straight: That sort of sound may be an indication of a number of problems. A whine during deceleration may mean there is a bad or loose pinion bearing.

What is a pinion bearing?

Pinion bearings are designed to reduce friction in the direction of desirable movement, increasing efficiency. In drive differentials, pinion bearings help the smallest gears in the differential work smoothly.

Can a pinion bearing cause vibration?

The pinion gear rotates at driveshaft speed and can mimic a driveshaft speed-related vibration. Improper pinion bearing preload can cause what appears to be a pinion seal leak, but the seal is fine, the pinion gear is moving vertically, horizontally, or diagonally as is rotates.

Do you grease pinion bearings?

Do NOT use bearing grease on your carrier bearings or pinion bearings when setting up your differential. This could cause premature failure from the oil not having the ability to lurbicate the bearings properly. Use clean gear oil only to pre-lubricate your bearings during the install.
