There are two different kinds of rear suspension fitted to the Trekker: the ‘swing axle’ assembly, that uses rigid axles, and the ‘IRS’ type – fitted to later models. Below is a brief breakdown of the different types of Volkswagen Thing suspension:
The swing axle assembly consists of a pair of rigid axles that pivot from the gearbox. If your axles only have rubber boots on the ends of the axles that join the gearbox (and not at the hub ends), then you have a swing axle model.
IRS is a more advanced type of Volkswagen Trekker suspension that features CV (constant velocity) joints both next to the gearbox and also at the hub end of the axles. These were only used on some later models. If your axles have rubber boots on both ends of axles (next to the gearbox and at the hubs), then you have an IRS model.
Of course VW Heritage stock an extensive range of parts for both types of VW Thing rear suspension, including axle and CV boots, hub seal kits and bump stops.
