My car has 62500 miles.
My car has an automatic transmission.

Hello. The motor mounts on vehicles in general should be inspected every 50,000 miles. I’ve seen motor mounts become excessively worn on vehicles with as low as 30,000 miles so it wouldn’t be a surprise if yours are due for replacement at 60,000 miles. The main part of motor mounts and made of rubber and sometimes the rubber what the teary rate quicker than average depending on the types of elements its exposed to (heat,cold,vibrations,and rough driving are elements in which a motor mount will be exposed). I would say the book time for the motor mount replacement is about an hour and a half. I will get a quote sent to you regarding the labor cost. To replace the crankshaft position sensor yes you will have to remove the motor mount, power steering pump and the timing belt. The crankshaft position sensor should be a 2.5 to 3.5 hour job. Technicians here at Yourmechanic could provide the repairs for you if requested.
