Why is my car uneven

Uneven tyre wear is caused by either worn bushes or incorrect tracking.

It sounds as though your car is 'toe in' and needs the wheels tracking - aligning. Take it to a tyre fitting bay - it doesn't cost much to have it checked/rectified.

Likely suspects include:
unevenly worn brake pads
unevenly worn brake discs or drums
air in brake lines
uneven tire wear
wheels out of alignment

Unless you can troubleshoot effectively and perform the needed repairs, I would take the vehicle in for service. It could end up saving you lots of time and money in unneeded parts and labor.

Cupping and uneven wear are for two different reasons. Cupping is caused by either an unbalanced tire/rim or bad shock. Uneven wear can be an alignment issue. I don't know how to set the toe in.

It probably is the regulator. GM has some plastic parts that break and the window gets uneven. The regulator can be bought at any parts store. Buy it with the motor attached or you will have to fight the cable unwinding. Usually cost under $100.

Unless one of your calipers is sticking or not engaging fully then there should be no reason for uneven wear unless you have a defective pad.

There will be uneven wear from the front to the back however. About 60% of the stopping power is provided by the front brakes and 40% from the rear , so your front brakes will wear faster than your rear brakes.

There are a multitude of ways a tire will wear unevenly and they all have unique causes. You can take it to a good tire shop and they will be able to diagnose what your specific problem and solution are.

check your coolant level

No and No. These parts are on them all and are absolutely Necessary for the Front end to stay alligned. This car will continue to Eat Tires until you replace these parts and get an allignment.

The Chardes have a diagonal split system, so one of the front discs is plumbed to the diagonally located rear drum.

You may need to check the front brakes too and that they have been bleed properly.

Other common cause of uneven braking are:

seized wheel cylinder;
brake hose obstruction or weakend wall;
weak pull off spring on shoe;
uneven drum roundness;
compensator/proportioning valve dicky.
