Is it time to replace?

• Common Symptoms: The related rack, panel, shaft, spray arm, or component may become loose, wobble, travel too far, or detach during normal use.
• Visible/Sensory Cues: Broken tabs, stripped threads, cracked plastic, missing hardware, looseness, or a retainer that no longer locks into place are common cues.

Pro Tip: Confirm the exact mounting position and inspect the mating shaft, rack, bracket, or hole before installation; damage to the mating surface can prevent a new retainer from holding.
