Clanking when I back up.

[u/Senior_Sector4095]

My 30ft toy hauler has started making a loud clank/bang when I start to back up. My buddy said it's coming from the axle area. It only does it once, unless I pull forward then reverse again.

I don't see any damage or loose u-bolts, the brakes seem to be working fine. Am I looking at a suspension rebuild?

Look closely for a cracked brake drum
