Hyundai Lower Engine Mount | Lower Torque Replacement Guide
Learn how to replace the lower engine torque strut mount on a Hyundai vehicle, also called “ROLL STOPPER.” In some cases, this may also be called a transmission mount. Once the lower engine mount fails, you will notice that your Hyundai jolts when changing gears due to excessive free play at the lower transmission mount.
This guide applies primarily to Hyundai vehicles with the four-cylinder engine, including Accent, Sonata, Elantra, Santa Fe, Veloster, and other models. Pictures and video are from a 2016 Hyundai Elantra.
Symptoms
- Hyundai jumps (bangs) into gear
- Excessive vibrations inside the cabin.
What you will need
- Hyundai Torque Mount
- Metric Socket Set
- Ratchet wrench
- Torque wrench
- Jack (two)
- Jack Stand
Procedure
- Park the vehicle on a level surface. Turn the ignition off and move the shifter into the Park position. Remove the key from the ignition.
- Jack up the car at the jacking points.
If you don’t have ramps, use a car jack and jack stands. - Secure the car with jack stands. Jacks alone are not enough to ensure that the car won’t fall.
- Remove the engine undercover, also known as the splash shield. It is held in place with several 10mm screws.
- Identify the lower motor mount at the back of the engine.
- For this task, you will need a second jack. Ideally, this should be a larger jack. You must place this jack under the engine to support it while removing the motor mount. Support the engine with the second jack. Use a piece of wood between the jack and the engine. This will protect the oil pan from damage. You don’t need to raise the vehicle. Simply use this jack to support the vehicle.
- Remove both 13mm bolts that secure the lower motor mount to the frame.
- Remove the 16 mm bolt that secures the lower engine mount to the bracket.
Hold the back nut with a wrench if the bolt starts to spin.
- Reinstall the new motor mount in reverse order. Tighten the mounting bolts to 80 lb-ft.
If you don’t have ramps, use a car jack and jack stands.
Hold the back nut with a wrench if the bolt starts to spin.
