knock in right front area
6 weeks ago bought used 2016 Sienna. After about 3 weeks, we noticed solid knock or pop in front right wheel area. Returned it to dealer, said if was defective strut, replaced under warranty. Week later, same problem. Happens most when braking during left turn. I walked beside car while wife slowly drove and problem definitely comes from wheel area. If strut was replaced, what else could this be.
