Trunnion Assembly, 0°Castor – TR2 – 4

Trunnion assembly with 0° castor suitable for Triumph TR2, TR3, TR3A and early TR4. History shows that these were fitted on the TR4 up to CT6343 (Wire Wheels) & CT6390 (Steel Wheels). The later TR4's were built with trunnions giving 3° castor to aid the steering, because of this new top wishbones were also fitted to move the pickup point of the top ball joint in line with the now angled vertical link. The top wishbone assembly is easiest way of checking which trunnion is fitted to your car. Always check both sides for wear ensuring no forwards & back movements can be made to the vertical link when installed in the trunnion. 2 required per car.
