My mechanic advised me that my wheelbearings were worn out on my front right tire assembly and that i would need to have the hub assembly replaced. This is after i brought the truck to him while hearing a unpleasent screeching noise everytime I turned to the right. I assumed that it was a power steering problem or perhaps a fluid pump issue. I have used this mechanic faithfully for over a decade and trust his assesment. I am curious how involved a job this is, how long the repair ought to take and what a job like this should cost, roughly?Thank You for your consideration!
