DV8 Steerable Knee Walker Parts

If you rely on the Drive 790 DV8 Steerable knee walker to stay mobile during a foot, ankle, or lower-leg recovery, keeping it in safe working order matters as much as the walker itself. This collection carries genuine replacement parts for the 790 DV8 Steerable knee walker, so a worn caster or a slack brake cable never becomes the reason you're stuck on the couch.

When the steering feels loose or a wheel drags, the Drive Caster Assembly (9503H79018) is the usual fix — it fits the front, rear, left, and right positions, so a single part covers any of the four wheel locations. Smooth casters restore the tight, responsive turning the DV8 is known for and prevent the pull-to-one-side that makes a scooter feel unsafe.

Braking issues typically trace to two components. The Brake Cable (9503H79023) stretches or frays with regular use and is the culprit when your hand lever no longer bites; the Right Brake Assembly (9503H79004) replaces the mechanism itself when the pads or hardware wear out. Both are engineered specifically for the 790 DV8, so you avoid the guesswork and fit problems that come with generic parts.

A few practical notes buyers ask about: these parts are model-specific to the Drive 790 DV8 Steerable, not the standard non-steering knee walkers, so match your model number before ordering. Most swaps require only basic hand tools, and replacing a caster or cable is far more economical than buying a whole new scooter. Ordering ahead — a spare caster or cable on the shelf — keeps a recovery on track without downtime.
