When changing out the clutch, should I replace the throwout bearing, and why? Does this part fail. What's the benefit.

 

Yes, it does wear out. Its a very cheap part. Since replacing it is just as expensive (or just as much trouble) as changing the clutch its crazy not to put a new one in when you replace the clutch. Unless you are just upgrading a very low mileage clutch and the oem tob works with your new one.

 

it's called a throwout bearing for a reason

 

Yea but we dont like spelling out tob. If you save the 50 or 60 and dont change it you'll kick urself later. Makes your car sound like a diesel truck when you're idleing with the a/c on.
