Question about 1998 Oldsmobile Aurora
I was told the rackinpinion stearing needed to be replaced, that it was causing the new tires on the front of the car to wear out on the inside. I paid an arm and leg to have this done, allignment and again another set of tires. The tires have been on the car less than 4 months and the inside on the front tires again show substantial wear and the now the front axle has separated from the boot on the passenger side. What the heck is wrong for this to happen, could it have been the CV axle the whole time that was causing my problems or is there some other issue that caused the front axle to fall apart
Unless there is noise or play when cornering sharply at low speeds (parking), the CV joint / boot is still ok. The joint does need grease in there and the rubber boot fitted properly very soon.
As the suspension is set, the axle does little more than provide drive. It doesn't affect toe-in or camber angle.
Camber angle (vertical tilt inwards) is a product of the suspension design, and often cannot be altered.
Weak front springs can also throw this angle out, as the vehicle sits too low.
Toe-in (forward point angle) can and must be set accurately, or you will skid about in wet weather depending which tyre grips more.
What is most important to you, is the tyre design, tread width and outer radius. Also the tyre pressures MUST be mid limit when cold on the front - otherwise excess wear will result.
Having tyres with a large contact area that are too rigid on the front will increase wear to the insides.
Also, it is good practice to rotate the tyres to even-out wear. Usually front tyres move to rear axle, and rears swap sides to front axle. If wear is uneven, pop them off and turn around before refitting. Some tyres you cannot do this with.
If you choose a tyre with a harder tread compound, or ones with "C" at the end of the code, these will again last a lot longer.
