How to Troubleshoot a Car's Clutch

Over time, a car's clutch wears out just like its tires. Generally, there are signs or symptoms that indicate there is a problem with your clutch. Here are some basic guidelines for troubleshooting your car's clutch before seeking the help of a mechanic.

Instructions

Difficulty: Moderate

Things You’ll Need:

• Car
• Clutch
• Owner's manual

1. Verify that your vehicle's clutch is the source of your problem and not the pedal-arm bushings, activating cables or the slave/master cylinder before you start to troubleshoot your car's clutch.
2. Take note of the gear you are using, how fast you are traveling, any unusual noises and whether the problem persists or disappears as you shift gears. Once you sense there's a problem, pay close attention to these variables for troubleshooting your clutch.
3. Examine your clutch's pressure springs, pressure plate and clutch disc if your car's clutch is slipping. Replace any worn or damaged parts.
4. Consider replacing your clutch cable or weak springs in the pressure plate if your car's clutch pedal sticks.
5. Check for air in the line, a bad cylinder, insufficient transmission lubricant or a poorly adjusted clutch linkage if your clutch drags or doesn't release properly.
6. Adjust your clutch, tighten or replace the clutch's "U" joint flange and lubricate its facings if your clutch chatters or grabs.
7. Replace your clutch's release bearing or worn shaft bearing if you hear considerable noise coming from your clutch.
8. Know when to call a professional. You may need to consult a mechanic if your transmission is loud when it's in gear, or if you've followed these basic recommendations and still have a clutch problem.

Tips & Warnings

• Don't drive with your foot on the clutch. "Riding" the clutch is a poor driving habit that causes your clutch to wear out prematurely.
