My daughters 99 olds alero is shuttering when the brakes are applied. I have replaced rotors and pads and still shakes. It does have a broken wheel stud on one of the front wheels. Also has 147,000 miles. Would wheel hubs need replacing?

Answer:

There may be an issue witht he hub bearings. There are two ways to check a hub bearing. One is to swirve a bit left than right while driving about 15-25 mph and listen for a whiring noise and the noise will change pitch as you swirve. For hub bearings that are in worse shape, Simply jack up the front end and grab hold of the tire and try to wigggle it top to bottom, any play or movement at all is from a failed hub bearing.

Another thing that can cause this is a bad spot on a tire. Rotating the front tires to the back and test driving it should let you know if this is the case.

One missing wheel stud will not cause an issue.

97 ETC/ Service Steering Sysyem ??? Information Center on at Each startup, ?? Belts and fluid are okay. Code 127???

Answer:

C1227 – Left Rear Excessive Wheel Speed Variation
C1228 – Right Rear Excessive Wheel Speed Variation
C1248 – EBCM Turned the Red Brake Warning Indicator On
C1255 – EBCM Internal Malfunction
C1287 – Steering Sensor Rate Malfunction
More than likely the ABS Code is C1287 and having the steering wheel position sensor replaced at the local dealer is all that is needed. Part is about $85 and Labor around $100. This is a common failure part and most likely they have the part in stock.

2004 Chevy Silverado 2500HD I just bought the truck and the radio isn’t working. Everything lights up like it’s on but no sound. The salesman that sold it said it was working at one time and thinks it has something to do with the Onstar button. The manual says the Onstar button will mute the radio when pushed and to push any button to restore the radio. But it doesn’t work. Any ideas?

Response:

does the radio go through all of it’s functions normally if the buttons are pressed?
