Transmission Mount Replacement - C Class - W204 - Mercedes-Benz


Transmission Mount Replacement Time: 3 hours Tab: $25 to $200 Talent: Tools: 16mm, 13mm socket, extension, floor jack, jack stands, wheelchocks, safety glasses, torque wrench Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Transmission mount Hot Tip: Put a piece of wood between the jack and transmission Performance Gain: Proper drive shaft alignment Complementary Modification: Check your flex disks The transmission mount provides many functions; it holds the transmission in proper alignment with the drive shaft, absorbs some of the drivetrain vibrations and helps transfer the torque to the drive train. The mount is made of metal and rubber. The rubber section does wear out. When this happens the drive train will fall out of alignment and can cause damage to other expensive components. One of the symptoms of the mount going bad is a sound when getting on or off the gas as the slop in the mount allows the transmission to flex in the mount until it hits the side of it. You can also start hearing and feeling a lot more drive train noise. If you suspect your mount is going bad safely jack up the car and have a look at it. You can see it clearly without moving any other components. If you feel it is bad place a piece of wood under the transmission, and slowly lift the transmission. If the transmission moves by itself you have a bad mount. To change the mount you will need to safely raise and support the front of the vehicle. Please see our article on safely raising and supporting your w204. Clunking sound when getting on or off the gas, could be it is time for a new transmission mount Applies to: C350 (2007-14), SLK350 (2004-14), CLS350 (2004-14), CLK350 (2005-14), E350 (2005-14), S350 (2005-14), SL350 (2005-14), R350 (2006-14), ML350 (2006-14), Viano (2005-14), Sprinter (2006-14), CLC350 (2008-14), GLK350 (2008-12)

Crankshaft Positioning Sensor Replacement - C Class - W204 - Mercedes-Benz Crankshaft Positioning Sensor Replacement Time: 2 hours Tab: $20 to $40 Talent: 1 Tools: T30 Torx Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Crankshaft positioning sensor Hot Tip: Use a mirror Performance Gain: Smoother running car Complementary Modification: Replace Camshaft positioning sensors Your fuel injection computer (DME) may output a code that indicates a faulty camshaft position sensor (CPS). This important sensor tells the car's computer where the flywheel is located in relation to the combustion cycle. The DME takes the signals from both the cam position sensor and crankshaft position sensor, and calculates when to fire the fuel injectors and spark plugs. If the crankshaft position sensor is not operating properly, your car will run very erratically or perhaps not at all. Replacement of the sensor is not as easy as the camshaf...

All of the mounting hardware is considered single use so make sure you order new hardware when ordering the bar. You will need to jack up the car and remove the front wheels along with the under body trays to perform...
