The internal bearings (top shaft, steering and diff) last a long time. The 5x10 wheel bearings are a big improvement over the 6x10's in the previous ride in durability due to being higher profile, but if you smack a wall pretty good they'll still get notchy.
Check them by taking them out, spinning on a pencil (with some pressure to simulate cornering, not just freewheeling). If they're crunchy, replace.

The ceramics are a good upgrade, they stay smoother much longer even with abuse.

I am running this car more often with longer run times since we are racing near the house in a school parking lot. I've been running for 1 1/2 hours each time I go race since I'm getting 45min on a 5000mah battery. This car is a blast!
