On an independent suspension, wheel bearings are located inside the spindle or steering knuckle. Each steering knuckle connects the wheel hub to the upper and lower A-Arms, with the CV shaft passing through the bearings inside the knuckle and into the wheel hub. On units with a solid rear axle; i.e, a 2001 Yamaha Warrior 350, the rear wheel bearings sit inside a single rear wheel hub. The solid axle connects to the wheel collar (which is bolted to the wheel), passes through the bearings located inside the wheel hub,...

Commonly Located: Drive belts are present only on ATVs and UTVs with an automatic transmission. The drive belt is located behind the crankcase cover and in between the primary drive clutch and the driven clutch. Note that in older service manuals the clutches may be referred to as a pulley or a sheave.
Physical Description: The drive belt is a black rubber belt, oblong in shape, with a number of deep grooves along the inside and outside edges. The edges of the drive belt are slightly tapered inward.
Commonly Located: An ATV has two sprockets; both located on the same side of the ATV. The drive chain is wrapped around each of the two sprockets. A smaller sprocket sits in the front of the drive chain, attached to the engine transmission assembly. The rear sprocket is much larger and sits toward the back of the ATV in the back of the drive chain. The rear sprocket is attached to the rear axle assembly. Note that not every ATV has a drive chain and sprockets. This is an assembly that mostly appears on sport quads and older...
