A Noisy and Bumpy Ride

Shaft Couplings

When I recently took my car into an automotive shop, because a rattling noise was competing in volume with my very loud radio and the front left wheel of my car seemed to be shaking much more then usual, I had no idea what was wrong. In fact, I had no idea that the shaking of the wheel andfavicon the rattling noise might be related, which is exactly what I was told the next day when a mechanic called me back with the quote. A shaft coupling had broken, he told me, after which I promptly asked him what a shaft coupling was. He explained that two shaft connected my wheels to the transmission, which was what provided by the power that made my car wheels move, as well as the control that made the wheels spin at the speed according to the amount of pressure I applied to the gas pedal. These two shafts, which obviously played a very important role in the running of my car, were connected to each other by way of a shaft coupling. Shaft couplings connected the shafts of all of my wheels to the transmission shafts, and without one my car had begun to shake and the loose coupling was clanging around within framework of my car.

Prompted by my further questions, which were being asked so that I fully understood why it was important that I paid him what he asked to fix my busted shaft coupling, the mechanic explained to me that shaft couplings did more then just connect on shaft to another, but also served as a stress buffer and an alignment fixer for the two shafts, which was why my wheel seemed to be going a bit crazy without it. Now fully satisfied that I desperately wanted the shaft coupling reinstalled, and told that more couplings, such as motor couplings and universal joints also helped keep my car together, I paid the man and drove home happy, shake and rattle free.
