Average Mileage: 84,250 mi (78,500 mi - 90,000 mi)
Verified
The rubber bond in the harmonic balancer can decay, which causes the balancer to move and work its way into the timing chain cover. If the balancer comes into contact with the timing cover while the engine is running, it will fracture and damage the timing case and potentially other surrounding parts. The harmonic balancer should be inspected at every service.

Balancer came off while driving, but belt stayed in contact with pulley as I was able to make it 3 miles home.
