What goes into the price

At an independent shop: about 1.0 hours of labour at around $120 an hour, plus about $80 in parts, for a compact SUV. Dealerships usually charge a higher hourly rate and use the carmaker's own parts.

These are Fixtimate's estimates of what shops typically charge, worked out from hourly rates, the time each job takes and parts prices. A shop's own price can differ: ask for a written estimate, then check it here.
