AWD rear differential bearing lubrication

The most common cause is the pinion shaft front bearing wearing out. The problem affects almost all all-wheel drive P3 platform models.

Yes. The front bearing can be replaced without removing the entire differential/Haldex package from under the car. A bearing set costs about 60 euros, while Volvo's complete differential replacement costs significantly more.

1. Remove the exhaust (center flange open, cut with a dull saw past the Haldex clutch). 2. Remove the drive shaft: mark the position on the front and rear flanges, bolts off. 3. Remove the Haldex package (4 bolts). Remember to disconnect the electrical connector and prepare for Haldex oil. 4. Scrape the spline off the pinion shaft end. 5. Replace the front bearing.
