Duration: Can be taken out and installed less than 1 hour




Before you do anything make sure you jack up the car and use jack stands to keep the car from moving. Also make sure the car has the e-brake on too.




Alright now for how to install:




Here's what we are looking. This motor mount here is where the bushing will be replace with the new bushing. The red arrows are showing the bushing and the bolts that will need to be remove. The 14mm bolt showing will also be another 14mm bolt on the other side of the motor mount as well. The 17mm shown will have a 17mm nut on the other side. You will need to use both wretch and a ratchet to uninstall this bolt.

Once you remove all the bolts and pull out the motor mount, it will look like this:

Here's what the motor mount actually look like completely out of the car:

Now the fun part about get the old bushing out. This will be a pain in the butt if you don't own a air ratchet or even a table vice grip to take this 14mm bolt off that is shown on this photo below. If you don't own any of these then you will need to do this. You will need to put the motor mount back on with just only 17mm bolt and nut. Make sure it's secure but not too tight. Now hold the motor mount up against toward the front of the motor to do the following. Then take your 14mm wretch and hit it with the rubber mallet or regular hammer and hit the side of the wretch to break the bolt loose. Once it loose you can unbolt 17mm bolt then finish taking out that 14mm bolt. One thing I will tell you, please don't lose the bolt pin that's make the 14mm tighten up. If you lose this then you will be screwed. I will show you that bolt pin on the next instruction.

Now this photo is what it look like when the 14mm bolt out of the motor mount and bushing taken out. Now what I mention before on the bolt pin. You will see the red arrow showing the bolt pin. Please and I mean please make sure you keep that in there or else you will be screwed. If you want to play it safe put duct tape over it so you won't lose it.

Alright here's a side by side of the new bushing "red" and the old bushing "black"

Here's the new bushings installed on the motor mounts with 14mm bolt installed as well.

Once you got the new bushings installed then go backward the steps on this instruction and make sure all bolts are secure, tighten and nothing loose. Then the start you car while on jack stands with e-brake and check underneath to make sure the motor mount isn't loose. If all look good then you can drop the car down and go for a test drive.



This is what it look like once you have everything back on the car and ready to go.
