No, the CV axle only allows the power from the engine to reach the wheels. It does not affect the alignment, which is what will cause uneven wear.
The tires could be unevenly inflated from one another. Also you could have 'shimmy' where your brakes or axle cause the car to veer slightly, which could also affect tire wear and steering, alignment and vertical balance. Start with properly inflating your tires, then get them rotated and balanced-- with any luck that could be all that you require.
Remove the front tires, from your Pontiac Grand Prix. Remove the brakes and rotors. Unbolt the axle from the suspension. Remove the axle.
They all have to be the same size. They can be different brands but even then make sure the tires on the front axle are the same brand an the tires on the rear axle are the same brand. Do not mix brands on the same axle.
If it is 4 wheel drive then there is a solid axle in the rear and a trans-axle in the front. the trans-axel has two CV shafts on either side connecting to the front tires. If it is 2 wheel drive then there is just a solid rear axle. and your front tires mount to spindles.
The new tires should be placed on the rear axle to lessen the risk of hydroplaning.
Cause vibration and will cause excessive tire wear. Can also cause suspension parts to wear prematurely and wear out the axle bearings. Have your tires rotated and balanced every 10,000 miles.
the axle or trans-axle
Perhaps bad tires or bent rims bad axle shaft? swap front tires for rear to see if problem persists
It is ok as long as you have the same size on each axle. In other words you must have the exact same size tire on the front axle or the rear axle. Never mix sizes on an axle.
Yes - as long as the tyres on the same axle have the same tread pattern.
No. You can't use an unserviceable tire, period.
No, not less one of the tires is out of balance. But it is never, ever, a good idea to have two different size tires on the same axle. This is a big no-no.
