Getting the power down - whatever the job
The Volvo FM is available with no less than 7 different rear axles - solo and tandem axles with single reduction or hub reduction. All the rear axles have the rear axle casing cast in nodular iron which results in a compact design offering high ground clearance. The wheel bearings are maintenance free unit bearings.
A differential lock is fitted as standard to the rear axle. It increases get-you-there ability when the surface is slippery and it offers little traction. Tandem axles also have a differential lock between the axles.
