Signs That Your Mazzulla Off-Road UCAs Need a Rebuild

  • Noisy Suspension: Squeaking, clunking, or popping sounds over bumps can indicate degraded heims or uniballs.

  • Uneven Tire Wear: Worn UCA components can cause poor alignment, leading to uneven tire wear.

  • Reduced Off-Road Performance: If your suspension feels less responsive on the trails, it may be time for a refresh.
