Porsche Cayman in the service shop for clutch replacement.
One of the most common repair procedures for the manual transmission Boxster is the replacement of the clutch assembly. Unfortunately, it is a rather big process involving the removal of the transmission. The good news is that it’s really not a super-difficult job if you have some information, and a few hints and tips.
How do you know if your clutch is beginning to fail? There are a few ways to tell. First, you should figure out how old your current clutch is. If your car is driven with mostly highway miles, then clutches can almost last forever. However, if you often drive around town somewhat aggressively, then you will probably have to replace your clutch at about 30,000 miles or so. With a hydraulic clutch system like the one on the Boxster, it can be a bit more difficult to determine the exact problem than with an older-style cable clutch system. Spongy pedals, excessive free play, and grinding noises all indicate problems with the clutch or hydraulic system. Strange noises that change when you push in the clutch pedal can indicate a pilot bearing or throw-out bearing beginning to fail. Finally, if your clutch begins to slip when the pedal is not depressed, then chances are your clutch disc is worn, or the spring plates in your pressure plate have worn out.
