Hi there, Susan!
It's always a good idea to seek a second opinion when it comes to stuff like this, given how expensive labor can be when it comes to fixing up cars. Labor hours can indeed vary based on the complexity of the job and the specific vehicle model. For a 2007 Lexus IS250:
- CV Axle Replacement: Typically, professional mechanics can take around 1.5 to 3 hours, depending on the complexity and the condition of the vehicle. Sometimes, the entire axle replacement can be more cost-effective than repairing individual parts.
- Front Brake Pads, Rotors, and Calipers: The time can range from 1 to 2 hours for pads and rotors per axle. Adding calipers can increase this time. However, 3 hours does seem on the higher side. It's important to note that labor times can be higher in shops with higher demand or specialized expertise.
Remember, labor rates can vary significantly from one shop to another, and higher-rated mechanics may charge more for their services. It's always a good idea to compare quotes from different shops and consider the reputation and quality of the service they provide.
If you have further questions or need more detailed advice, feel free to write back!
