What is the price range to replace all 4 wheel bearings?
You need all 4 replaced, really? Call some shops in your area and get some price quotes.
Why do you think you need all four wheel bearings replaced? For all four to go at once is unheard of. You are more likely to get struck by lightning than to have all four wheel bearings go bad all at once.
Wild guess: $1000, give or take a couple hundred. A proper diagnosis is in order before throwing this kind of money at a car.
$1000 would probably be at the low end, but hard to believe you need all 4.
