Trunnion Bushes for Vehicle

Trunnion bushes are the polyurethane bush kits used to replace worn rubber bushes at the front upper control arm outer trunnion pivot position on applicable classic British vehicle platforms. The trunnion is the pivoting kingpin assembly at the outer end of the upper control arm that allows the steering swivel and suspension to move together, and the bushes at its pivot positions control the compliance and articulation of the arm at that interface. Worn trunnion bushes introduce play and imprecision into the front upper arm pivot, contributing to steering vagueness, increased NVH and front suspension looseness that worsens with age and use.

Quality polyurethane replacement trunnion bush kits restore correct pivot compliance at the outer trunnion position, eliminating play and delivering more precise, controlled front suspension movement on applicable classic platforms. A targeted restoration solution for workshops and experienced DIY users carrying out front suspension overhauls on applicable classic British vehicles. Installation time is approximately two hours.

Why Upgrade Suspension?

On classic vehicles equipped with trunnion-style front upper arm pivot assemblies, the trunnion bushes are among the oldest and most service-critical components in the front suspension. Unlike more frequently serviced components, trunnion bushes on classic vehicles can remain in place for decades, accumulating wear and compliance drift that progressively loosens the front upper arm pivot and degrades steering feel, front end NVH and suspension precision.

Replacing worn trunnion bushes with quality polyurethane alternatives as part of a front suspension restoration eliminates play at the outer upper arm pivot, restores correct pivot compliance and delivers a more precise, refined front suspension character that reflects a correctly restored and correctly operating classic front end.

Trunnion Bush Range

The trunnion bush range includes:

• Front Upper Control Arm Outer Trunnion Bush Kits: Polyurethane bush kits for the outer trunnion pivot position of the front upper control arm on applicable classic British platforms, restoring correct pivot compliance and eliminating play at the upper arm outer interface.

Why Purchase Trunnion Bushes?

Allowing worn trunnion bushes to remain in service on a classic vehicle with this front suspension design leaves the upper arm pivot operating with play and compliance beyond its designed tolerance, contributing to a loose, imprecise front end that cannot be fully corrected through steering or wheel alignment adjustments alone. Renewing them with polyurethane bush kits as part of a front suspension restoration ensures the trunnion pivot is correctly compliant and the upper arm operates through its correct range of motion from a properly supported interface.

For workshops and experienced DIY users carrying out complete front suspension overhauls on applicable classic British platforms, trunnion bush renewal is an essential step in achieving a thorough and correct restoration result.

Repair and Upgrade

Trunnion bushes are manufactured from high-strength polyurethane engineered to withstand the load, vibration and environmental exposure that front upper arm trunnion pivot positions are subject to over the service life of a classic vehicle. Resistant to oil, heat and road contaminants, polyurethane trunnion bushes maintain their compliance characteristics for longer than original rubber alternatives, delivering more consistent pivot performance throughout the restored vehicle's service life.

Who Trunnion Bushes Are For

Trunnion bushes are a practical solution for:

• Professional workshops carrying out complete front suspension overhauls and restorations on applicable classic British platforms requiring correct trunnion bush renewal at the front upper arm outer pivot position.
