• Premature wear & bushing failure


OE bushing material composition allows premature wear.


Install improved Sonnax rear center support bushing to restore critical clearances and resist untimely wear.


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.
