You can tackle engine mount bushings replacement at home if you have the right tools and a good attitude. Safety matters, so take your time and get ready before you start. This project feels rewarding, and you’ll learn a lot as you go.
Key Takeaways
Get important tools like a hydraulic press, jack stands, and new bushings before you begin. This helps make the job easier.
Put safety first by looking for space near the firewall. Use a block of wood to hold up the engine. This stops damage and keeps you safe.
Replace bushings one step at a time. Check alignment after you finish. Good alignment stops vibrations and helps your bushings last longer.
Engine Mount Bushings: Tools & Safety
Tools & Materials
You need certain tools to change engine mount bushings at home. Make sure you have these things ready before you begin:
Hydraulic press or a big bench vice
Jack and strong jack stands
Socket and wrench set
Pry bar
Torque wrench
New engine mount bushings (YNF Rubber is a good brand for bushings)
Block of wood (to keep the engine sump safe)
Safety gloves and goggles
Penetrating oil
Shop rags
When you pick new bushings, you will see different materials. Here is a simple chart about the most common types:
Material | Benefits | Drawbacks |
|---|---|---|
Natural Rubber | Very tough, does not tear easily, handles heat well | Does not handle gas, ozone, or flames well |
Neoprene | Handles acid, ozone, flame, water, and oil well | Not easy to find for most mounts |
Silicone | Handles high heat; good for hot places | Tears and wears out faster |
EPDM | Tough, strong, does not tear easily | Does not handle oils and acids well |
Safety Tips
Safety is always the most important thing when you work under your car. Here are some tips to help you stay safe:
Always check for space near the firewall before you lift the engine. This keeps radiator hoses and AC lines safe.
Never hold up the engine by the oil pan. Use a block of wood to keep the sump safe.
Make sure the motor and wheels are both held up well before you go under the car.
Look for any inside damage, especially if your car was in a crash.
Know your car’s road history and check everything before you drive again.

Before you begin, gather all your tools and watch a video or guide. Watching someone else do it helps you feel ready and sure about each step.
Step-by-Step Replacement
Vehicle Prep
You want to start with a safe workspace. Park your car on a flat surface. Set the parking brake. Lift the rear of your car and place it on sturdy jack stands. Use a floor jack with a 2×4 to support the engine. This keeps the engine steady while you replace motor mounts. Remove the battery cable for safety. If you work on the passenger side mount, take out the alternator first. For the driver side, remove the air filter housing and a couple of small brackets on the transmission. These steps give you more room to work.
Removing Old Bushings
Getting the old engine mount bushings out can feel tricky, but you can do it. Here’s how you make it easier:
Relieve pressure off the mount by gently jacking the transmission up a little.
Place a cloth to protect the bell housing while you work.
Position the jack right under the mount. You don’t need it flush, just enough to support the transmission.
Jack up until you see the engine or transmission shift slightly upward. This means you’ve relieved the pressure.
The through bolt should slide out easily now. Don’t over jack—just enough to take the load off.
When you’re pressing motor mount bushings out, a hydraulic press works best. If you don’t own one, check with your local auto parts store. Autozone lets you rent a strut/suspension tool kit for free. The kit has round dies that fit the bushings and hold the bracket steady. These dies look like big sockets and make the job much safer.
Replacing Engine Mount Bushings
Now you’re ready to install new engine mount bushings. YNF Rubber makes reliable bushings for this job. Before installing bushings, use a P-80 lubricant. This special lubricant helps the new bushings slide in without damage. It’s made for automotive assembly and works well with tight-fitting rubber parts.
Follow these steps to replace motor mounts and get the alignment right:
Lift the rear of your car and set it on jack stands.
Support the engine with a floor jack and a 2×4.
Remove any parts blocking access, like the alternator or air filter housing.
For the rear mount, take out the four bolts on the brace below the mount. Use a pry bar to get enough play to remove one of the bolts.
For the front mount, remove the shifter linkage, the brace under the engine, and the cross-member. A wobbly socket helps loosen the engine mount bolt.
Press the new bushings in using a hydraulic press or the rented tool kit.
After installing bushings, check alignment. If things look off, loosen the rear mount and use a pry bar and jack to adjust it.
Tip: Always double-check the alignment. Misaligned bushings can cause vibrations and extra wear.
Final Checks
You want to make sure everything is perfect before you finish. Here’s a checklist to help you:
Inspect for any damage from shipping or handling.
Remove all covers or packing materials from the motor.
Check for signs of vibration or moisture if the motor was stored before installation.
Drain any oil added for shipping.
Make sure the motor sits on a firm, flat surface.
Verify the alignment of couplings and belts.
Open condensation drains at the lowest points.
Confirm nothing blocks the motor’s ventilation.
Check the lubrication system and add grease if needed, but don’t overfill.
For horizontal motors, check for soft foot conditions and use shims to fix uneven spots.
For vertical motors, make sure the shaft and coupling are within the limits.
Review manuals for any special installation requirements.
After you replace motor mounts, start your car and listen. Watch for excessive engine movement, vibrations, or abnormal handling. If you feel a shake when you engage the clutch or see the transmission move too much, check your work. Sometimes the shifter jumps during acceleration if something isn’t right.
You save a lot of money by doing this yourself. Here’s a table showing the cost savings for different car models:

If you use aftermarket engine mount bushings from YNF Rubber, you can get a longer warranty. Some aftermarket bushings offer five years or even lifetime coverage. Many people have replaced bushings themselves and kept their warranty, as long as they followed the instructions.
Note: Always read your car’s manual and follow the steps. If you’re unsure, ask a friend or watch a video. You can do this!
Troubleshooting & Maintenance
Common Issues
You might run into a few bumps after replacing your engine mount bushings. Many people find these problems:
Reported Issue | Description |
|---|---|
Time Consumption | The job can take 6-7 hours, so plan for a long day. |
Difficulty with Bolt Direction | The way you insert bolts can make the job easier or harder. |
Challenges with Bushings Removal | Some bushings are tough to remove and may need extra effort. |
Exhaust Component Removal | Sometimes you need to loosen the exhaust to get better access. |
If you notice new vibrations or noises, check for these causes:
The engine may not be centered, or the bushings could be misaligned.
A failing motor mount or transmission mount can cause extra shaking.
Sometimes, stiffer aftermarket bushings add more vibration.
Incorrect installation or using the wrong parts can lead to binding.
To check for misalignment, follow these steps:
Inspect mounts for cracks, rust, or oil damage.
Remove and inspect coupling bolts.
Make sure all surfaces are clean and dent-free.
Use alignment tools to pre-position the engine.
Measure gaps with a feeler gauge and adjust as needed.
Recheck after adjustments and torque bolts to spec.
Tip: Always double-check your work if you feel a vibration or hear a clunk. A failing motor mount can cause bigger problems if left unchecked.
