Stop power steering fluid from weeping past the input shaft with the Sunsong Steering Gear Input Shaft Seal Kit 8401621. This seal kit is a direct-fit replacement for the 1980 GMC B6000, restoring a tight seal where the steering gear's input shaft enters the housing.

The input shaft seals ride against the rotating input (stub) shaft to keep hydraulic power steering fluid inside the gear. Over time these seals harden and lose their sealing surface, which can let fluid seep out at the shaft. If worn input shaft seals are the cause of a leak at your steering gear, this kit supplies the parts to reseal that area.

  • Application: a direct-fit replacement for the listed 1980 GMC B6000 application.
  • Job: seals the steering gear input shaft to help contain power steering fluid.
  • Signs it may be time to replace: power steering fluid seeping at the input shaft or a dropping fluid level — diagnose the source before replacing.
