What It Helps Address

• Crankshaft vibration transmitted through the engine
• Worn or deteriorated rubber bond in the original balancer
• Noise or imbalance related to a failing harmonic balancer
• Drive belt alignment concerns tied to balancer wear
• Service replacement needs on Toyota 4Runner, Pickup, and T100 engines

Installation Notes and Tips

Verify pulley groove count, mounting dimensions, and keyway style before installation. Confirm engine application by year and model, since 594-575 is listed for 1988-1995 Toyota 4Runner, 1988-1995 Toyota Pickup, and 1993-1994 Toyota T100. Use proper service procedures and torque specifications during installation to protect the crankshaft and balancer interface.

Quality Assurance

Dorman builds this harmonic balancer to meet stringent standards for tensile and impact strength, supporting long-term durability in standard replacement service. The bonded rubber design is intended to maintain vibration control under normal engine operating conditions.
