When Does Alternator Bearings and A/C Bearings Go Bad??
Hi,
I have a 01 Civic Coupe with 138,000 miles. (Midwest in the U.S.) I started to get a whining noise from the engine about a month ago. As the engine idles and I press the gas the noise gets louder and/or the "whine" gets louder, stronger and a little higher pitched. As I let off the gas and the engine idles slower, the noise quiets down some to a 'soft whine'. As long as the engine runs, the noise exists. The dealer said BOTH the alternator bearings.... and the......... A/C bearings are shot and both need replaced. Both the alternator and A/C are original equipment on the car. Does this seem to match the symptoms? Do alternator bearings go bad? Do A/C bearings go bad? Is a thousand bucks about the right cost to replace BOTH the alternator and A/C? Thanks!! Whining in Columbus |

It is becoming a fairly common problem on this version of Civic. I had to have it replaced in my '04 Civic last year. I seriously doubt that the A/C has anything to do with it. I suggest finding a good private mechanic who specializes in imports. |

No. I hope no shop will try to squeeze $1000 out of you for these
minor bearing noises. Even a complete timing belt change including new idler pulleys and water pump wouldn't cost more than $500-700 on a Civic. AC bearing does NOT rotate when the AC is on. So if you turn on the AC and the noise goes away then you know. Alternators should last about 100-120 K miles without replacing the brushes or the bearings. I think you got good service out of it. Rockauto.com lists a Bosch remanufactured alternator at about $120+core +shipping. Should be about $200 incl. labor if you have shop replace it. AC clutch bearing is replaced as a part of the entire clutch. My guess is about $40-50 bucks + labor. On Aug 17, 8:57*am, Vmusic > wrote: > Hi, > *I have a 01 Civic Coupe with 138,000 miles.
