Minor Car Problems

My wife's car started making noises near the left driver tire last month when we were on the road and it disappeared, but came back again last week. She brought it in, we're looking at the front hub assembly needing to be replaced. There is a couple in our church struggling financially (husband's employer was bought out and they have demoted him twice with pay cuts but expect him to be a manager at a cashier pay rate), so the husband is going to see about getting the part and doing the repair for us and we'll pay him instead of an auto-shop.
