Ferret erratic knocking from left hand side front.
We drove a Ferret about 15 miles to a Canada Day parade with no problem but during the parade, it started to knock once loudly when braking to a standstill. This was coming from LHS front, outside the hull. By the end of the parade, the knocking was much worse. Multiple knocks, erratic, not related to wheel speed, like someone hitting the outside of the hull with a hammer, and only when drivetrain was loaded. I could feel the impact on the hull from the inside. When coasting downhill, i.e. unloaded, there was no knocking.
No obvious loose suspension parts. Pulled the brake drum off and no breakage or loose parts.
For info, I dismantled the hub a while back to replace the brake backing plate.
Anyone experienced this ?
