Unless both bearings on all side of the wheels are overworked, there is no need to replace them all at once. You should only swap out the ones that need it.
What is the life expectancy of a wheel bearing?
The average wheel bearing will have a lifespan of 136,000 to 160,000 km (85,000 to 100,000 miles). Certain factors such as the quality of the wheel bearings, installation, and car modifications can affect its actual lifespan.

How do I know if I need front or rear wheel bearings?
#2 – Grinding Noise
A common symptom of bad wheel bearings is when your tires have a loud grinding noise coming from them. This is caused when the wheel bearings lose their lubricity and build up a lot of heat inside of them instead.
How do you tell if it’s a front or rear wheel bearing?
Jack up the rear end and test each wheel to hear/feel the bearing for noise or roughness. Then do the same for the front end. If you can’t safely jack the whole end, then do it one wheel at a time.
How often should wheel bearings be replaced?
Most serviceable wheel bearings need maintenance every 25,000 to 30,000 miles, or during every brake service. But, the average life of a sealed wheel bearing and hub assembly is about 85,000 to 100,000 miles, without the opportunity for a technician to repack the bearings.
How often do bearings need to be greased?
Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.
