This bulletin provides instruction on how to replace rubber isolator components to maximize system safety and lifetime in 257- and 267- series side mount systems.
ENP-536
It may be necessary to replace worn rubber isolators in 237 series side mount systems. This communication provides how to modify the isolator, and remove and replace with new isolator material. In some cases, the isolator rib or ribs may split and move away from the main channel. This communication also provides how to remove and replace such portion with a section of isolator material.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
