How to replace the rear wheel bearing on a Smart 451

Model: Smart Smart 451 - Years 2007-2015
Part: Wheel

Here’s how to replace the rear wheel bearing on a Smart 451. First, lift the car; do not rely solely on your jack, use a hydraulic jack and two axle stands instead. Remove the wheel. Take out the T30 screw from the hub; the central nut is a 16. If the central cover does not come off easily, spray it generously with WD-40, let it sit, then use a hammer and chisel to remove the cover. You can find the new part on eBay with the code 323977680705 for £64.00. Since it includes the hub, it is a bit easier to replace. The tricky part is keeping the driveshaft in place; otherwise, you won't be able to unscrew the four bolts securing the hub. Replace the bearing, applying copper grease; secure it with the new bolt and refit the wheel. Job done.
