How do you know if starter is bad in Toyota Avalon?

1 If you have concerns, there is very well likely that you have a problem

2 Does it make a screeching sound just as it starts up?

3 Check the connecting bolts on the starter, if loose or broken it will ruin the starter eventually

just had mine replaced starter $250 plus labor

my mechanic took one hour to replace it but he is very honest on his labor charges
