2011 WRX with 51k miles, car has been babied and not drive hard, clutch creaking noise when depressing clutch when engine on and off.
1. checked all pedals and mounts inside car. everything looks normal, no brake pedal flexing when pushing clutch in, which is related to firewall problems other wrx people found with welds.
2. found many WRX firewall issues causing clutch creaks. checked all 6 firewall welds and did not see from the outside looking at the spot welds behind the windshield wiper motor broken or flexing.
3. traced creak noise with help of someone pushing clutch in to under the intercooler. removed intercoole and found clutch slave cylinder making creaking sound. unsure if the cylinder is making the creaking noise or the pressure plate inside the transmission.
anyone have ideas on seeing if creak is coming from slave cylinder or pressure plate? I could unbolt the slave cylinder and see if it makes creak but i don't think it will make creak when not under pressure.
any ideas would be appreciated. i'm new to WRXs and clutches and don't know if manual trannys are built well and it's probably just the slave cylinder or if these WRX clutch/pressure plates don't last past 50k miles under normal driving conditions.
