Description

Overview
Eliminate intense drivetrain shudder, clunking gears, and power loss with the premium GMB GUM-99 Universal Cross Joint (U-Joint). Precision-engineered by GMB, a legendary Japanese manufacturer of OEM and aftermarket driveline components, this heavy-duty cross joint is built specifically to handle the high rotational torque of rugged 4WD and AWD configurations. Installed directly into the propeller shaft/driveshaft assembly, the GUM-99 plays a vital role in transferring smooth, continuous power from the gearbox to your drive wheels while seamlessly flexing under heavy load and suspension movement.

Key Features

  • Premium Japanese Craftsmanship: Built by GMB to meet or exceed strict original equipment parameters, ensuring superior balance and an ultra-long service life.
  • Angle Lube Design for Easy Maintenance: Comes equipped with an angled grease fitting right in the center of the cross, allowing for straightforward routine grease top-ups to maximize bearing life.
  • Carburized Alloy Steel Core: The cross journal is hot-forged and heat-treated in a specialized furnace, creating a hardened outer layer that aggressively resists surface indentation and wear under high-torque towing or off-roading.
  • Precision-Matched Needle Bearings: Tightly packed needle rollers encased in robust steel cups guarantee low-friction rotation and eliminate physical drivetrain slop.

    • The GMB GUM-99 universal joint is an exact replacement engineered primarily for popular Mitsubishi 4×4 pickup trucks and mid-to-full-size SUVs, including:
