A drive axle is essentially a half axle, so named because it does half of the job, extending from a transaxle or differential to one of the wheels. Its twin on the other side completes the set.

Freightliner Trucks has announced that factory-installed Meritor front drive axles, which allow for All Wheel Drive (AWD), are now optionally available on its Business Class M2 106 and 106V models.

Q:Your answer to this question will settle a bet: My friend says that four-wheel-drive F-250s and F-350s always had solid axles up front. I say that from 1980-1985, all 4WD F-Series had TTB up front.
