SCHEDULE AN
2008 Porsche 987 Cayman S arrived here at Daniel’s European with a gearbox noise issue, and we shipped out the gearbox to Bill Rader Motorsports LLC to get it diagnosed and serviced. BRM located the source of the noise in the gearbox being the worn main shaft bearing in the bell housing.
It is up high and in front of the differential, which doesn’t always really get a good supply of oil. As shown in the pictures, all of this wear likely happened because of the factory oil being in the box too long. Furthermore, BRM mentioned that the factory oil is poor quality and recommends using Mobil 1 75/90 or Motul 300LS instead. After confirming the issue, BRM replaced all the worn components and shipped the gearbox back to us to install.
Being one of the most reputable Porsche gearbox specialist, we are proud to be working with Bill Rader as he has built the gearboxes that won in the GT class in the grueling 24 hours of Daytona in 2009 and 2011, along with numerous other race wins, including championships in SCCA, World Challenge, Grand Am, and ALMS.
