How to Get the Best Motor and Transmission Mount Bushing
There's nothing wrong with being picky, especially when you're buying replacement car components or accessories. Nowadays, bogus and low quality products are rampant. That's why you have to be extra cautious. Purchasing car parts that perform crucial mechanical functions may entail a more careful selection process; buying motor and transmission mount bushings is a good example. To get the best bushings for your car, consider these simple tips:
How to achieve proper fit
- Buy a direct-fit motor and transmission mount bushing to be sure that it fits your car perfectly. A bushing should never be one size smaller or larger than the motor mount, or else it won't work properly. A large bushing would just wobble constantly and that would damage the mount eventually.
- Achieving the right fit means getting the precise dimension of the bushing. Always compare a new bushing with the old one. You may also use a special measuring tool to determine the accurate diameter size of the bushing.
How to select the right type
- Bushing types can be determined by the kind of material used to produce the bushing. The most popular type is the polyurethane bushing. This special material combines the features of rubber and metal. The soft cushioning element of rubber helps in reducing friction around the motor mount, while the toughness of metal provides extreme protection against wear and tear. This bushing type is referred to as "soft," and it is perfect for regular day-to-day driving for it provides a very quiet drive.
- "Hard" bushing is required for extreme driving conditions. This works best for trucks and race cars. It is made from the same polyurethane material, but there's an added shock-absorbing capability that allows the bushing to withstand intense vibrations around the transmission.
Other things to consider:
- Motor and transmission mount bushings are located in several sections of the car: it can be at the front, rear passenger side, or front driver side. As much as possible, check all sides and verify which bushing needs to be changed and buy the corresponding replacement bushing.
- It's better to buy motor mount bushings that are sold in kits to save time, money, and effort. Kits include all the necessary hardware and accessory that you need to install the bushing with ease.
Car Maintenance: Changing the Motor and Transmission Mount Bushing
Just like the other components in your car, the motor and transmission mount bushings may deteriorate over a certain period of time. However, it's really hard to predict the exact time when you have to replace them because the rate of wear of the motor bushings depend on your driving habits and requirements. That's why a regular car maintenance check up is necessary to keep your car in tip top shape. After checking the bushings and you noticed that they are broken, you have to replaced them immediately. Here are the ten easy steps on how to change the bushings.
Difficulty level: Difficult
- 3/8-inch drive ratchet set
- Wrench set
- 6-inch pry bar
- Car jack and stands
- Wheel chocks
- Blocks of wood, preferably 2x4 inches
- Engine parts aerosol cleaner
- Torque wrench
- Bearing grease
- Replacement bushings
Refer to this method when replacing the motor and transmission bushings on top or side mounted motor mounts. Changing the bushings at the bottom of the motor mount requires a different procedure.
Step 1: Place the wheel chocks behind the rear wheels to prevent them from rolling backwards when the front frame of the vehicle is lifted.
Step 2: Raise the car and secure the four sides of the its frame on the jack stands. Make sure that the car is evenly lifted on all corners. Place a wood block on the lifting point of the jack. See to it that the engine rests on top of the jack.
Step 3: Find the motor mount's edge that is attached to the engine. Remove it from the engine with the use of an open end wrench.
Step 4: Find the motor mount's other edge that is connected to the car's frame. Disconnect it from the frame with the help of a pry bar.
Step 5: Locate the motor mount bushing. Pop the old bushing out of the motor mount. Dispose it properly.
Step 6: Spray liberal amount of the aerosol cleaner on the motor mount. Wipe off any dirt with a rag. Remove all dust particles before installing the new bushing.
Step 7: Apply lubricant on the inner part of the motor mount hole and the outer surface of the bushing. With the use of a C-clamp, insert the bushing into the motor mount. Press the bushing firmly on the mount and hand tighten it.
Step 8: Repeat the same procedure to replace the other bushings.
Step 9: Reattach one side of the motor mount to the engine, and the other to the car frame.
Step 10: Tighten all nuts and bolts to secure the motor mount in its place. Lower the car by carefully removing the jack and stands. Test the car to see if the engine is working properly.
