Step-by-Step Installation Process
Step 1: Prepare the Vehicle
Begin by parking the Honda Civic Si on a flat surface and engaging the parking brake. Use a jack to lift the front of the vehicle and secure it with jack stands.
Step 2: Remove the Wheels
Using a socket set, remove the lug nuts and take off the front wheels. This will give you access to the suspension and differential.
Step 3: Drain the Differential Fluid
Place a drain pan under the differential. Remove the drain plug and allow the old fluid to completely drain out.
Step 4: Remove the Differential Cover
Unbolt the differential cover using a socket set. Carefully pry it off to avoid damaging the gasket.
Step 5: Remove the Old Differential
Take out the old differential by removing the ring gear bolts and sliding it out of the housing. Be cautious of any shims that may fall out.
Step 6: Install the Youtec Limited Slip Differential
Carefully insert the Youtec LSD into the differential housing. Ensure that it is seated properly and reinstall the ring gear bolts, tightening them to the manufacturer’s specifications.
Step 7: Reassemble the Differential
Replace the differential cover with a new gasket. Tighten the bolts in a crisscross pattern to ensure an even seal.
Step 8: Refill with Gear Oil
Using a funnel, refill the differential with the recommended gear oil until it reaches the fill level indicated in the owner’s manual.
Step 9: Reinstall the Wheels
Put the front wheels back on, securing them with the lug nuts. Lower the vehicle back to the ground.
Step 10: Test Drive
After the installation, take the Honda Civic Si for a test drive. Pay attention to the handling and ensure there are no unusual noises coming from the differential.
