Freezing the bushing wouldn't help if metal shrinking is the goal. You would only be shrinking the ring that goes on the control arm, making it harder to get on. Freezing the control arm probably won't work as it is a solid piece of metal and, since it is still on the car, you would need a drive in freezer to roll your car into. I'm guessing not a lot of us have the means to test the freezing theory. Also, WD40 doesn't work, you need actual grease. |
