One problem related to front suspension lower control arm has been reported for the 2002 Chevrolet Avalanche. The most recently reported issues are listed below.
I was driving my 2002 chevy Avalanche through a parking lot, turned the steering wheel to the left to drive up to my bank's atm, when the left front tire appeared to buckle under the vehicle and the left front of the truck fell to the ground. The left front a-arm and wheel assembly broke due to premature metal fatigue.
