Bushwhacked! Keys to Avoiding Preventable Bushing Problems
Brian Wing
Symptoms:
- Premature wear & bushing failure
Cause:
OE bushing material composition allows premature wear.Correction:
Install improved Sonnax 2-6/3-5-R hub rear bushing to restore critical clearances and resist untimely wear.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.
