Trunnion bushings are the polyurethane bushing kits used to replace worn rubber bushings at the front trunnion and pivot positions of the lower control arm on applicable classic applicable vehicles. On these platforms, the outer end of the front lower control arm uses a trunnion and pivot arrangement in place of a conventional ball joint, providing the steering knuckle with its ability to pivot for steering while articulating through the suspension travel arc. The trunnion bushings at these positions provide the compliant bearing interfaces that allow the knuckle to rotate smoothly and correctly through its full steering and suspension travel range. As these bushings deteriorate with age and use, the trunnion and pivot interfaces develop play and harshness that directly degrades front wheel location, steering precision and handling character.
A correctly renewed trunnion and pivot bushing kit restores the correct interference and compliance at both the trunnion and pivot positions, eliminating play and returning smooth, precise and correctly supported front knuckle articulation. The trunnion bushing range covers a front trunnion and pivot bushing kit for the applicable classic applicable front suspension design. Backed by a limited lifetime warranty. Installation guide included.
The trunnion and pivot front suspension design used on applicable classic platforms ages in a way that is distinct from modern ball joint suspension. Because these are not standard ball joints that can be assessed and replaced in isolation, the condition of the trunnion and pivot bushings is the primary determinant of how precisely and smoothly the front steering knuckle pivots through its range. Wear at either the trunnion or pivot position introduces play at the outer end of the lower arm that manifests as front wheel looseness, vague and imprecise steering response, increased front end shimmy and the characteristic looseness that trunnion wear produces in the steering system of applicable classic vehicles.
On vehicles that have covered significant mileage or have been in storage, the trunnion and pivot bushing material may have hardened, cracked or deteriorated to a point where the knuckle is operating with significant play at the outer arm position. Renewing both the trunnion and pivot bushing positions together with correctly specified polyurethane alternatives restores correct and precise knuckle articulation, eliminating the front wheel play and steering looseness that deteriorated trunnion bushings introduce.
The trunnion bushing range includes:
On applicable classic vehicles, a worn trunnion and pivot assembly is frequently the primary source of the front wheel looseness and steering vagueness that develops with age, yet because the trunnion design is less familiar than modern ball joints it is sometimes overlooked during front suspension diagnosis. Renewing the trunnion and pivot bushings restores the correct interface at both positions simultaneously, addressing the full articulation compliance of the outer lower arm in a single kit rather than requiring separate sourcing of individual components.
For workshops and restorers completing front suspension restorations on applicable classic platforms, trunnion and pivot bushing renewal is a straightforward and high-impact service that restores correct front wheel location and steering precision from a correctly renewed lower arm outer pivot interface.
Trunnion bushings are compatible with:
The front trunnion and pivot bushing kit installs at the trunnion and pivot positions at the outer end of the front lower control arm. Installation requires no significant dedicated labor time when completed as part of a front suspension or steering service. An installation guide is included with the product. For additional technical assistance, a dedicated support team is available to confirm correct product fitment for the specific platform and trunnion pivot configuration.
The trunnion and pivot bushing kit is manufactured from polyurethane engineered to withstand the steering load, angular articulation and environmental exposure that front trunnion and pivot positions are subject to throughout the service life of a classic vehicle in everyday and restored use. Polyurethane maintains correct trunnion and pivot compliance for longer than the original rubber or nylon alternatives used at the time of manufacture, ensuring the front knuckle pivots correctly and with minimal play throughout the restored vehicle's service life.
Trunnion bushings are a practical solution for:
The right trunnion bushing kit restores correct articulation compliance at both the trunnion and pivot positions, eliminates front wheel play and steering looseness, and delivers precise, stable and correctly supported front suspension behavior throughout the restored vehicle's service life.
Explore the trunnion bushing range and find the right kit for your vehicle. With a front trunnion and pivot bushing kit for applicable classic passenger and performance vehicles, you can restore correct front knuckle articulation compliance and complete every classic front suspension restoration with confidence.
