Symptoms
Oil weeping from a portal, on the inside of the wheel or onto the brakes. One owner noticed a leaky rear portal about 2,000 miles after buying his 718.
The fix, step by step
- Drain the portal, pull the hub, and replace the outer bearing and seal.
- The parts are standard sizes: owners list the outer wheel bearing as 9006245 (50.8 × 101.6 × 20.6 mm, sold as RLS16) and the seal as 7161340461 (70 × 90 × 10 mm).
- Clean out the old oil and refill with the correct wheel-drive oil.
