Replace those rotten rubber parts to avoid a bigger headache


Equating motor mounts and O-rings with Star Trek and Roman fire gods might be a bit of a stretch, and yet without the chemical miracle of Vulcanized rubber the automobile as we know it might not exist in this timeline. In reality, 25-plus years behind the wheel of 25-plus-year-old cars has taught us that replacing old rubber parts with new ones makes the difference between driving a creaky museum piece and enjoying a factory authentic classic motoring experience.

Having recently acquiring a 1934 Chrysler AirFlow, this is one of the first things I recognized needing attention. The motor and tranny mounts were mushy, and no longer able to cushion.
We sent these out for refurbishment and, voila, total transformation as the vibrations ceased, noise in the cabin reduced, and the motor visibly became less agitated.
Some vehicles I’ve owned had to be inspected very carefully as in some cases rubber grommets and bushings had totally disintegrated. After researching, parts had to be reintroduced to the car to correct issues that posed both performance and safety concerns.
Newly upgraded parts are often available now in alterate materials like urethane and silicone for many vehicles. A little research is recommended to see what might best be used when replacement is considered. In most cases, peace of mind is a byproduct of having addressed these maintenance items,and the older the vehicle, the more benefit is realized.
