UPDATE: I was taking a trip a month back that was about 200 miles round-trip and the sound came back. Since then it's pretty consistent from 30 mph on up. Would it be worth tearing off the Passenger side CV, stub axle, and doing the same bearing replacement on the passenger side? I'd love some input. Also, at 343k now so there's a lot going on with the drivetrain and suspension parts that I will need to address in the near future (outer tie rods, rear axle seals, rear brakes, and an alignment). Good news is I managed to snag a spare 3.4 this summer with 115k on the odometer so I'm prepped for when the old dog gives out on me. Fingers crossed it isn't any time soon.
