Here's the deal. I called Honda to see how much it would cost for them to replace my throwout bearing because I've noticed it hissing lately. They tell me it will take them 8 hours and $630 Labor to replace the bearing. Are they giving me a load of crap?!? Also, how bad is this throwout bearing hurting the car? Is it something that has to be replaced or it will start to affect the clutch? If you guys could give me any kind of advice that would be great. I just couldn't believe it when he told me 8 hours to do this.
