What is the size of bolt to a 2002 Chevy cavalier front axle?

There isn't a single bolt size for the entire front axle of a 2002 Chevy Cavalier. The axle uses multiple bolts of varying sizes depending on what component you're referring to. You'll find different sized bolts for:

* Wheel studs: These secure the wheels to the hub.

* Caliper mounting bolts: These hold the brake calipers in place.

* Control arm bolts: These connect the control arms to the axle.

* Steering knuckle bolts: These secure the steering knuckle to the axle.

* Other miscellaneous bolts: There are likely other smaller bolts securing various components to the axle assembly.

To determine the correct bolt size, you need to specify the exact component you're working on. A repair manual specific to your 2002 Chevy Cavalier is your best resource. This manual will have diagrams and specifications for all the bolts on the front axle. You can also find this information online through automotive parts websites by entering your vehicle's year, make, and model. Remember to always double-check the size before purchasing any replacements.
