Warning:

Use of an arbor press is required for correct installation. Do not use a hydraulic press or a bushing driver/hammer combination to install, as doing so may distort the bushing and cause fitment issues.

Symptoms:

• Bushing wear
• Bushing failure
• Clutch failure
• Harsh shifts
• Gear ratio & solenoid codes

Cause:
Premature wear due to sub-optimal OE bushing material in ZF 8-speed units allows fluid loss and misalignment that results in harsh shifting and clutch failure.

Correction:
Install improved Sonnax "A" hub front bushing to restore critical clearances and resist untimely wear.

• Material: Steel-backed alloy
• Bushing Style: Precision
• Housing Bore: 1.419"
