Symptoms:

  • Leaking front seal
  • Pump noise
  • Excess converter hub-to-bushing clearance
  • Low pump volume

Cause:

OE bushings are machined in place and drop-in replacement bushings are not thick enough, resulting in too much hub-to-bushing clearance.

Correction:

Sonnax finish-in-place bushing replicates the OE pump bushing and has a steel-backed bronze lining.
