Triumph Herald Rear Axle & Differential

The Triumph Herald rear axle and differential deliver power from the propshaft to the rear wheels, with the swing-axle design defining the model's distinctive handling character. Built from 1959 to 1971, all Herald variants from 948cc to 13/60 share core differential components.

Keeping Your Herald Axle in Top Condition

Worn differential bearings and leaking seals are common issues causing noise and oil loss. Regular oil changes extend component life significantly, and replacement mountings restore precise handling.
