Background of the car, had a leak in my power steering pump that I had patched, and had the front wheel bearings replaced. whenever I get to about 40 mph, the tires sound quite loud, however they quiet around 45 and don’t get loud again until about 65. However, when I go left around a bend the noise disappears. Also, maybe unrelated sometimes when I back up and then put it into drive, the car stalls out. I’m curious if this issue just means that I need to replace my power steering pump or if it might be something else?
It’s a 2005 ford Explorer.
