Solid Diff Bushes vs Rubber Diff Bushes
Solid bushes sharpen up the rear end, rubber keeps it quiet. Here is how to decide which diff bushes suit your car.
George Bull, owner 1 min read
On an independent rear suspension car the diff is held in the subframe by bushes, and worn ones are a common cause of clunks that get blamed on the diff itself. When they need replacing you have a choice to make.
Solid or polyurethane bushes
Solid bushes stop the diff moving under load, which means sharper throttle response and less wheel hop. The downside is that gear noise and road noise travel straight into the body.
Rubber bushes
Factory style rubber bushes keep the cabin quiet and are the right choice for a daily driver. For a car that sees track days or hard launches, we normally recommend polyurethane as the middle ground.
