How to Replace Motor Mounts

Motor mounts are the connection point between the engine block and the car’s frame. The motor mounts are made of durable rubber that acts as a cushion between the engine vibration and the chassis. The engine simply rests on the motor mounts. Solid motor mounts would be too uncomfortable for daily driving. Over time the motor mounts will lose their firm but pliable properties and will wear out causing noises and bumps until replaced, especially when shifting from reverse to forward drive gears. 

Tools and Supplies Needed to Complete this Job

1. Eye Protection
2. Gloves
3. Jack Stands
4. Floor Jack / Tranny Jack
5. Pry Bar
6. Socket Wrench, Sockets, Wrenches

Removal Instructions

In order to replace your motor mounts, you will need to follow some basic safety precautions.

Step 1 - Park the vehicle on a flat and level surface that is firm enough to support the cars weight.

Step 2 - Set the emergency brake and turn the engine off.

Step 3 - Block the rear tires, front and back

Step 4 - Lift and support the front of the vehicle onto the Jack stands.

Step 5 - Inspect all electrical connectors to make sure there is leeway to lift the engine up a few inches without stretching or worse yet breaking anything.

Step 6 - Loosen and remove the motor mount bolts.

Step 7 - With a floor jack or tranny jack, lift and support the engine a few inches, until you can remove worn out mounts from the frame.

Installation Instructions

Step 1 - With the engine supported by the jack, install the new motor mounts and secure them to the frame. Tighten to manufacturers specifications.

Step 2 - Lower the engine onto the new motor mounts.

Step 3 - Remove jack stands and lower vehicle to the ground.

Best Practices

  • Check all motor mounts when replacing one
  • Check transmission mounts when replacing motor mounts
  • Check for motor oil leaks and repair so the oil won't destroy the new mounts
