VW Jetta Clutch Slave Cylinder Bearing LSC320

This is a concentric clutch slave cylinder with an integrated release bearing, crossing to LSC320, for manual-transmission Volkswagen and Audi cars. The listed fitment is Volkswagen Jetta 2000-2018, Golf 2002-2011, Golf R 2012-2013, GTI 2006-2014, Beetle 2002-2017, CC 2009-2016, Eos 2007-2011, Passat 2006-2008 and 2012, and R32 2004 and 2008, plus Audi A3 2005-2013, A3 Quattro 2005-2018, S3 2000-2012, TT 2007-2010, TT Quattro 2000-2009 and TT RS Quattro 2012-2013. VW and Audi used more than one slave cylinder across these years depending on the gearbox, so lay the new unit next to your old one and confirm the mounting ears and line connection match before the transmission goes back in.

Signs the slave is done: the clutch pedal slowly sinks to the floor or feels soft, the master cylinder reservoir keeps dropping with no leak you can see under the vehicle, fluid drips from the bellhousing inspection area, gears grind going into first or reverse because the clutch will not fully release, or you hear a growl or squeal that changes when the pedal is pressed. A bearing that has worn through can also score the pressure plate fingers.

A concentric slave cylinder lives inside the bellhousing, so replacing it means pulling the transmission. That is also why most shops replace it any time the clutch is out: labor is already paid for, and a slave that starts leaking a month after a clutch job means doing the whole job twice. To install, clean the input shaft bearing retainer, slide the new unit over it, torque the mounting bolts evenly, and reconnect the hydraulic line with new O-rings. Once the transmission is back in, bleed the system until the pedal is firm and returns fully, then check that the clutch releases cleanly before the first drive. Use the brake fluid the master cylinder cap calls for.
