In vehicles with AXOD & E ('88-'92) transmissions it is common for the lower sun gear bushing to wear. The sun gear holds two bushings, an upper and lower bushing. The upgraded Sonnax bushing 96009-01 replaces the lower and upper sun gear bushings.
Beginning in 1989 the upper bushing was used only to control oil flow, and is not used to support the sun gear.
