How to Lubricate Wheel Bearings?


A wheel bearing is an integral component of your drive-axle assembly of the car. These components help the wheel rotate smoothly and are responsible for decreasing the friction caused due to other drive train components. Proper lubrication and care will boost the longevity of the vehicles and help them do their job smoothly. Step by step procedure must be adopted while lubricating the wheel bearings that have been listed as follows:

Taking the Outer Races Out 

Clean the hub and races using paraben. Clean it by separating the races from each other, and the inner and outer races will be of different sizes. Ensure that you start with the first one. Consider the socket as a drift and use it. Pick the larger race that fits perfectly with, the smaller one.

If the races are of similar size, take out the first one using a flat punch or heavy hammer. Tap the alternate sides and work evenly to avoid tilts or jams. Avoid scratching the hub from within. Bring the second one out using a socket or adrift as the first race is out.

Check and Clean the Bearings

Check and Clean the Bearings

This is a critical step that must be cautiously performed while lubricating the wheel bearings. First, clean every part using Parafin or white spirit. Ensure no grease on the brakes while cleaning the stub axle. In routine lubrication, allow the outer surfaces to stay on the stub. Check the bearings for slight indentation, and in case of intense pitting or scoring, a wheel bearing replacement must be carried out as soon as possible. Nothing is acceptable in the case of rollers or balls getting an entirely new bearing in case something happens to them. Try buying it from a trusted store and pay the labor charges to the mechanic.

Bearing Lubrication: The Right Way of Doing It

Bearing Lubrication

Start by tapping the outer races into the hub by using the old races as drifts. Ensure that the tapered roller race is fitted in the right way. Refer to the owner’s manual before applying the grease to check the quantity to be applied to it. There are different methods to lubricate the wheel bearing; sometimes, the grease is to be added in the center in excess while others need it in light amounts. Make sure that every area is covered during the grease application.

Reassembling the Hub & Bearings

Hub axle consisting of thread axle and shoulder base must be lightly greased and prevent its entry within the brake parts. Take extra caution while moving the hub to the axle and avoid knocking off the inner race of the outer ball bearing using the axle end; if the hub sticks, try tapping it using a soft-faced hammer. Try to insert the inner race of the external roller bearing.

Try inserting the thrust washer, and the chamfered side should be towards the bearings. Screw the hub nut and perform some hub adjustments. Place the castellated nut whose alignment must match the split pinhole. Try inserting the new split pin with the head uppermost and legs open. Try to reassemble the brakes.

How Much Does Wheel Bearing Lubrication Cost?

The wheel bearing lubrication generally depends on the car you own and the mechanic you refer to. You just need to pay $152 to the mechanic to let the wheel bearing do their job properly. However, you can save money by purchasing wheel bearings from customers’ trusted online car parts and accessories stores like ‘The Auto Parts Shop‘ and save money.

The Bottom Line

When left unlubricated, wheel bearings can impact the car’s performance. Follow the steps stated above to carry out proper lubrication by yourself. Associate with customers’ trusted online car parts and accessories stores like auto parts for wheel bearings grease. If the old wheel bearings are no longer in use, get a new one instead of driving the car as it is. Remember that working of every part must work smoothly so that you don’t end up getting disappointed and end up spending more on costly repairs in the future.
