* Mechanic Skill Level: A professional mechanic familiar with the vehicle will be significantly faster than a novice DIYer.
* Access and Tool Availability: Easy access to the bearing and having the right tools (including a wheel bearing press) will speed up the process. If specialized tools are missing or access is difficult, it will take longer.
* Condition of the Vehicle: Rust, seized bolts, or other complications can add considerable time to the repair.
Rough Estimates:
* Professional Mechanic: 1-2 hours per wheel, assuming no unexpected complications.
* Experienced DIYer: 3-6 hours per wheel, potentially longer if problems are encountered.
* Novice DIYer: 6+ hours per wheel, or possibly much longer, and may require multiple attempts.
Important Note: This is just an estimate. It's crucial to consult a repair manual specific to your 2007 Chevrolet Montana for detailed instructions and potential pitfalls. Attempting this repair without proper knowledge and tools could lead to further damage to your vehicle. If you're not comfortable with automotive repair, it's always best to take it to a qualified mechanic.
