Many mustang drivers reported having a squeak noise in the front suspension when going over a bump. I'm on my 3rd control arms and I'm going to the dealer next week to get a 4 replacement control arms put in. I just realized....the noise is ONLY there when the weather is very hot. I live in New York City and these past few days it's been 70 degrees, 55 at night. The noise is completely gone. Even after driving for an hour....the noise is not there. When I drive in 80 degree weather the noise is there and very loud. This means at a certain temperature the control arms squeak, then when it cools down the noise is gone. What do you think is a good solution to this?

 

Be different, only drive yours in the winter.

(Sorry, couldn't resist )

 

Intercool the control arms.

 

Don't hit bumps
