Knocking In Bushings
A knocking sound coming from your suspension could be a sign of worn-out bushings. Bushings are rubber or polyurethane components that connect different suspension components together. Over time, bushings can wear out and cause knocking noises as you get metal on metal contact.
Why Upgrade Bushings?
There are several benefits to upgrading your car's suspension bushings to polyurethane bushings. Polyurethane bushings are stiffer than rubber bushings, which can improve handling and reduce body roll. They are also more durable than rubber bushings, which can extend the life of your suspension components.
What Is Polyurethane?
Polyurethane is a synthetic plastic that is known for its strength, durability, and resilience. It is also resistant to oil and chemicals, making it a good choice for suspension bushings.
Benefits & Cons Of Polyurethane
Benefits:
Improved handling
Reduced body roll
Increased durability
Longer life of suspension components
Cons:
Can be stiffer than rubber bushings, which can make the ride harsher
Can squeak if not properly lubricated
High Tech OEM Bushings
Some car manufacturers are now using polyurethane bushings as original equipment (OEM) parts. This is because polyurethane bushings offer several advantages over rubber bushings.
Squeaking Bushes
Polyurethane bushings can sometimes squeak, especially if they are not properly lubricated. To prevent squeaking, it is important to lubricate the bushings with a silicone-based grease.
Prevent Squeaking
To prevent polyurethane bushings from squeaking, follow these tips:
Lubricate the bushings with a silicone-based grease or apply PTFE tape
Make sure the bushings are properly installed
Drive the car for a few miles to break in the bushings
