Why is my car shaking on acceleration? How do I fix this? Those are dire questions to people who find themselves in that situation. A car that shakes on acceleration can be very annoying and dangerous. There are many different causes and there are also some convenient solutions.
The most common reason for having a car shaking on acceleration is that you need a new tire on the one or more of the wheels that drive the car. For example, if you have a very bad tire in the front on a front wheel drive then there is a chance that this could be your problem. You can simply fix this by changing the tire. Rotating the tire to the back may make the problem a little easier to deal with but you may still have some shaking in the car when you drive. The main reason why a bad tire causes your car to shake is simply because it has lost so much tread that the wheel is no longer in balance. An unbalance tire can ruin the ride quality of any car no matter what is causing the imbalance. Unfortunately, you can’t balance a wheel if the tire itself is throwing off the balance. You’ll have to change the tire to fix the problem.
Another problem that you can run into that causes your car to shake on acceleration is a broken flex disc or flex joint. This is a rubber coupler that connects the driveshaft to the differential for the rear wheels. If this flex joint or flex disc begins to rip or tear them you can experience a very rough ride when you are accelerating. This was a major problem on Mercedes Benz E320’s and E420’s. There’s more than enough information on those car that can be easily found on Google’s search engine. If you continue to ride with a broken flex disc or flex joint then you can run the risk of it breaking completely which will throw the driveshaft into the frame of the car or even the differential.
Of course there are many other problems that can also be specific to certain vehicles, but these are some of the causes that can have an easy fix.
