How to Switch to a New Steering Flex Disc
Your car's steering flex disc serves as a link between the transmission and the driveshaft. Usually made of solid rubber, this component is prone to wear and tear over time. When the steering flex disc starts to malfunction, you can immediately notice changes such as vibrations coming from the drivetrain. You need to verify first if it's the steering flex disc that's busted. If you find any sign of damage, such as distortion, cracks, and missing pieces, then it's best to have the disc replaced. To help you speed up the replacement, we have provided the steps that you can use as a guide:
Difficulty level: Moderate
Things to prepare:
- Socket set
- Safety gloves
- New steering flex disc
Step 1: If you have just driven your car a few minutes ago, make sure you let the engine cool down first before touching any of the components under the hood. Leave the engine for a couple of minutes, and start working when the engine is cool enough to touch.
Step 2: Raise your car using a jack and let the rear sit properly onto jack stands. To get to the steering flex disc, you need to take out the exhaust system and the exhaust heat shield. But if you are using an AWD vehicle, then it's best that you remove the entire exhaust system.
Note: It's recommended that you replace the self-locking nuts and bolts of the driveshaft flex disc together with the steering flex disc.
Step 3: Take out the center heat shield that goes through the driveshaft tunnel. Get to the transmission of your vehicle, and locate the three 18mm steering flex disc fasteners. You need to remove these fasteners to get better access to the disc.
Step 4: Get a prybar to take the lever driveshaft away from the transmission. Alternatively, you can also use a large, flat-blade screwdriver to do this. Fetch a rope or a mechanic's wire, and use it to support the driveshaft while you work on the disc.
Note: It shouldn't be hard to pry out the driveshaft away from the transmission. If the driveshaft doesn't move at all, then there's probably a bolt that got left out.
Step 5: Proceed to working at the flange side of the transmission. Remove the three steering flex disc mount fasteners. Take note that you need to replace the flex disc nuts as well; these are self-locking, thus should not be reused.
Step 6: Unwrap the new steering flex disc package. Place the new driveshaft flex disc into place, and install the fasteners. Tighten them in place, while making sure that the arrows on the flex disc point toward the flange.
Step 7: After successfully assembling the flex disc, install the whole disc assembly to the transmission, and tighten the fasteners.
Step 8: Next, tighten the steering flex disc to the driveshaft fasteners. Be careful not to tighten them too much; otherwise the attachment may break, and cause the installation to fail. Lastly, reinstall any of the components that you took out during the replacement such as the exhaust system and exhaust head shield.
