How To Fix A Subaru Clutch Slip

A clutch slip can be a frustrating issue that affects the performance of your Subaru, causing the engine to rev without the expected acceleration. Knowing how to fix a Subaru clutch slip can help you address this problem and restore your vehicle’s performance. In this article, we’ll guide you through the steps to diagnose and fix a clutch slip, along with some tips to prevent it from happening in the future.

What Causes a Clutch Slip?

Before diving into the repair process, it’s important to understand the potential causes of clutch slipping. A clutch slip occurs when the friction material on the clutch disc can no longer effectively engage with the flywheel, leading to a loss of power transmission. Some common causes include:

• Worn Clutch Disc: Over time, the clutch disc wears out and loses its grip.
• Oil Contamination: Leaking oil from the engine or transmission can coat the clutch, causing it to slip.
• Damaged Pressure Plate or Flywheel: Damage to these components can prevent the clutch from fully engaging.
• Incorrect Clutch Adjustment: If the clutch is not adjusted properly, it can lead to a partial engagement.

Step-by-Step Guide to Fixing a Subaru Clutch Slip

Step 1: Inspect the Clutch for Wear

The first step in fixing a Subaru clutch slip is to inspect the clutch components for wear and damage. Start by accessing the clutch assembly, which may require removing the transmission. Look for signs of wear on the clutch disc, pressure plate, and flywheel. If the clutch disc appears thin or the flywheel is scored, it’s time to replace these components.

Step 2: Check for Oil Leaks

Oil leaks can cause the clutch to slip by contaminating the friction material. Check the area around the engine rear main seal and transmission input shaft seal for any signs of oil leaks. If you find oil on the clutch disc or flywheel, the affected components will need to be cleaned or replaced, and the source of the leak should be fixed before reassembly.

Step 3: Replace the Clutch Components

If you’ve determined that the clutch disc or other components are worn or damaged, replacing them is necessary. Purchase a quality clutch kit that includes a new clutch disc, pressure plate, and throwout bearing. Follow these steps to replace the clutch:

1. Disconnect the battery and remove the transmission to access the clutch assembly.
2. Remove the old clutch disc, pressure plate, and flywheel (if needed).
3. Install the new components, ensuring that the clutch disc is aligned properly.
4. Reattach the pressure plate and use a torque wrench to secure it evenly.
5. Reinstall the transmission and reconnect any components that were removed.

Step 4: Adjust the Clutch Pedal

After installing the new clutch, adjust the clutch pedal to ensure proper engagement. The pedal should have a slight amount of free play before it engages the clutch. Refer to your Subaru’s service manual for the correct pedal adjustment specifications.

Step 5: Test Drive and Check for Symptoms

Once the clutch has been replaced and adjusted, take your Subaru for a test drive to ensure the clutch slip is resolved. Pay attention to any unusual noises, vibrations, or signs of slipping during acceleration. If the issue persists, consider seeking professional assistance.

Preventing Clutch Slip

To prevent future clutch slip issues, follow these tips:

• Avoid Riding the Clutch: Keep your foot off the clutch pedal when not shifting to reduce wear.
• Perform Regular Inspections: Check for leaks and inspect the clutch system periodically.
• Address Issues Promptly: Resolve any clutch problems as soon as they arise to prevent further damage.
