Does a CV axle from Pontiac sunfire fit on Chevy cavalier?

A Pontiac Sunfire and a Chevy Cavalier share many common parts, especially during the years they overlapped production. However, it's not a guaranteed fit. While they might be the same, there's a chance of slight variations depending on the specific year, engine, and transmission of each car.

To be sure, you need to:

* Check the year, engine, and transmission: Even if they're both Cavaliers and Sunfires, different years and drivetrain configurations might use different CV axles.

* Compare part numbers: Find the part number for the CV axle on your Cavalier and compare it to the part number of the Sunfire CV axle you have. This is the most reliable way to ensure compatibility.

* Visually inspect: If you have both axles, compare their dimensions, splines, and overall design. Even small differences can prevent a proper fit.

Don't just assume they're interchangeable. Using the wrong CV axle can lead to serious problems, including damage to your transmission or even accidents.
