  • Sale
  • $13.16

Symptoms:

  • Bushing failure
  • Reaction carrier shaft damage

Cause:

Oil leakage due to inadequate support of the reaction sun gear.

Correction:

The Sonnax sun gear bushing is more than one-and-a-half times as wide as the OEM and maximizes bushing support.

Warning:

Measure the sun gear bore. Installing this bushing into a bore that is smaller than 1.705”-1.706” will result in a tight fit with the mating reaction shaft.
