I checked the shape of the bushings on my EG. I picked up this car not too long ago & want it as a drag strip/road race car. Replace the bushings high on the list.

Most of the bushings were ok, so I won't touch them until I have more track time w/ the car. I wanted to see which bushings NEEDED replacing now.

What I noticed:

Rear
- Lower control arm bushings ok, not the best, but ok
- Upper control arm bushings on the arm end ok; on the body end they NEED replacing
- The shock mount bushings on the lower control arm NEED replacing. Very cracked

Front
- A Arm bushings ok
- All balljoint bushings ok
- Shock mount bushings NEED replacing. Very cracked

As I noticed & you read, the front & rear shock mount bushings were very cracked & needed replacing. Why would those crack the most?

I don't understand how that point gets a lot of stress as the body is on one end of the LCA & the rotor assembly on the other side should keep it stable... right? How are they supposed to work? Up & down w/ the shock? Or back & forth w/ the A arm? Both?

- What other stress points should I look out for or replace for what I plan on doing w/ the car?

Thank you for all your answers.

 

The Shock fork mount bushings become worn and cracked so easily because they take the most abuse in regards to wear and tear + weather conditions. They are often neglected when it comes to lubrication and care.

Under load, as the control arm travels upward, the shock/spring assembly is being compressed. As the shock rebounds and extends outward again, it pushes against the control arm. That pushing and pulling motion at the shock fork is a lot of stress for a rubber bushing to handle. This is from what I have been told.
