BMW E90 REPLACE FRONT SHOCK ABSORBER STRUT INSTALL HOW TO 325i 328i 330i 335i

Introduction

This tutorial provides a step-by-step guide on replacing the front shock absorber struts on a BMW E90 series, specifically for models 325i, 328i, 330i, and 335i. If you're experiencing noise or clunking sounds from the front suspension, replacing the struts and strut mounts can help restore a smooth ride.

Step 1: Prepare the Vehicle

• Use a jack to lift the front of the car.
• Secure the car with jack stands at designated points to ensure stability.
• Place an additional jack in the center for extra support.
• Apply PB Blaster (or a similar penetrating oil) to the strut bolts to ease removal.

Step 2: Remove the End Links

• Locate the end link and use a 17 mm socket to remove the bolt on one side.
• Hold the other side with a crescent wrench to prevent it from moving.
• Take the end link off and set it aside.

Step 3: Disconnect the Strut Assembly

• Use an 18 mm socket to remove the strut bolts.
• Again, use a crescent wrench on the opposite side to keep the bolt steady.
• Remove the small bracket near the strut if applicable.

Step 4: Loosen the Control Arms

• Identify the lower control arm and loosen the bolts using a crescent wrench and ratchet.
• As you loosen the bolts, the control arm will drop, allowing more space for strut removal.
• Make sure to support the brake line using a jack.

Step 5: Remove the Old Strut

• Once the control arms are loose, carefully drop them down to create enough space for the strut.
• Use a hammer to gently tap around the strut area if needed to dislodge it.
• Carefully slide the old strut out, ensuring not to damage surrounding components.

Step 6: Install the New Strut

• Position the new strut into the assembly area, aligning the nubs with the holes.
• Raise the control arms back into position, making sure the holes align.
• Use a jack to apply pressure to the suspension, ensuring stability as you tighten the bolts.

Step 7: Reattach the End Links

• Reconnect the end link, making sure it is securely fastened.

Conclusion

Replacing the front shock absorber struts on your BMW E90 can significantly improve ride quality and eliminate annoying noises. After completing the installation, it's advisable to check all connections and take the vehicle for a test drive to ensure everything is functioning properly. If you encounter any issues, consult a professional for assistance.
