Is your Subaru WRX not shifting as smoothly as it used to? If you’re experiencing a slipping clutch, difficulty engaging gears, or any other clutch-related issues, it may be time for a clutch replacement. In this post, I’ll walk you through the essentials of replacing the clutch in a 2017 Subaru WRX, including tools needed, costs, and step-by-step instructions.
When Should You Replace Your WRX Clutch?
A clutch isn’t something you’ll replace regularly, but high-performance cars like the WRX are known for putting a strain on this part. You’ll know it’s time for a new clutch if you experience any of the following:
Clutch Slippage: If your engine revs but the car doesn’t accelerate as expected, your clutch could be slipping. This is often most noticeable during rapid acceleration or steep inclines.
Difficulty Shifting: Grinding or struggling to engage gears, especially first or reverse, may indicate clutch wear.
Spongy or Sticky Clutch Pedal: A change in the pedal feel—like it sticking to the floor or feeling too soft—may signal a problem.
Unusual Noises: Grinding or squealing sounds when you press the clutch could point to clutch damage.
Tools You’ll Need
Here’s a quick rundown of the tools and equipment required for the job:
Socket Set (10mm, 12mm, 14mm, 17mm)
Torque Wrench (to apply proper torque settings)
Jack and Jack Stands (for safely lifting the car)
Clutch Alignment Tool (essential for aligning the new clutch disc)
Screwdrivers and Pliers
Clutch Kit (includes clutch disc, pressure plate, and throwout bearing)
Estimated Time and Costs
Labor Time: Replacing the clutch on a WRX can take between 6-8 hours for a professional mechanic. DIYers with experience can expect around 8-10 hours.
Cost: A clutch replacement at a shop can range from $1,200 to $1,800, depending on labor rates and parts quality. A DIY replacement will cost you around $400-$800 for the clutch kit and any additional tools if you don’t already have them.
Step-by-Step Clutch Replacement Process
Lift the Car and Secure it: Use a floor jack to lift the car and place it on jack stands to give you access to the transmission and underbody.
Remove the Transmission: Start by disconnecting the driveshaft, transmission mounts, and any wiring connected to the transmission. You’ll need to remove the transmission to access the clutch assembly.
Remove the Clutch: Once the transmission is out of the way, unbolt the clutch pressure plate and remove the clutch disc.
Inspect the Flywheel: Check the flywheel for wear or damage. If it’s grooved or damaged, consider resurfacing or replacing it.
Install the New Clutch: Use the clutch alignment tool to properly position the clutch disc. Attach the new pressure plate and torque the bolts to the manufacturer’s specifications (typically around 18-24 ft-lbs for the pressure plate bolts, but consult your manual).
Reinstall the Transmission: Once the clutch is properly aligned and installed, reinstall the transmission, ensuring everything is connected back in place correctly.
Test the Clutch: After reassembling, test the clutch to ensure smooth operation before taking it for a test drive.
Clutch Torque Specifications
Pressure Plate Bolts: 18-24 ft-lbs (consult your manual for exact specs).
Flywheel Bolts: 54 ft-lbs (always verify based on your WRX model).
