Condition
Some customers and/or technicians may comment on a small amount of grease seepage from a brass or gold colored fitting located at the bottom of the strut assemblies. Note: At first glance, this may appear to be a fluid leak.
The 5th generation Camaro Z/28, as well as the 6th generation Camaro ZL1 1LE, employ a different type of strut than other traditional car and truck lines. These struts are specifically designed and tuned for the precise vehicle handling that these vehicles are capable of.
Cause
This condition may be caused by a vent allowing breathing within the damper body. There is no oil within this chamber but there is some grease on the inner walls of the housing that keeps the insert tubing lubricated against the component’s bushings. As air enters and exits this vent, it is normal to have small amounts of this grease exit the strut. This is actually part of the natural operation of these struts.
Correction
No strut replacement is required for this condition listed above.
