BMW F30/F31 wheel bearing replacement
How do you replace the F31 rear wheel bearing, are special tools needed?
The F30/F31 rear bearing is a press-fit in the housing and locked with a circlip, not bolted on like on the F10. The driveshaft is removed and the bearing is pulled out with a puller. Installing it requires a slide hammer and a threaded sleeve. Check the condition of the axle's bearing end at the same time.
Which bearing brand suits the F31 rear wheel bearing?
Recommended brands are FAG and SKF. With cheap Korean bearings durability varies: some last well, some fail much sooner. A quality bearing is the safer choice.
What should be noted when replacing the front hub on an all-wheel-drive car?
The disc and caliper are removed first. The hub bolt and the hub's four bolts are single-use, and all tightening is done by torque and angle. If the dust cap cannot be fitted back onto the new hub, grease is applied only on top of the hub bolt. The exact values can be found in the service manual.
