When you’re driving on the highway and hit 60-70 mph, does your car start shaking?
It can be terrifying when your car starts shaking while you’re driving on the highway. You might think that there’s something wrong with your car.
In most cases, the cause of a car shaking at high speeds is either an unbalanced tire or a misaligned wheel. Luckily, both of these problems are easy to fix yourself.
This article will show you how to identify and fix the problem.
What is a car shake or shimmy?
A ‘car shake’ is also known as a ‘shimmy .’It’s when your vehicle vibrates or oscillates front to back, left to right. It only happens when traveling at certain speeds – usually between 50-60-70MPH.
What Causes My Car To Shake When I Hit 60 -70 mph?
Many things can cause your car to shake at certain speeds. Here are some of the most common causes:
Worn shocks or struts can send subtle or severe vibrations throughout the chassis of your vehicle.
How to fix:
Grab your front bumper and attempt to move it side-to-side and up and down. If there is play in the suspension, this can cause your vehicle to shimmy.
2, Bad tires
Having bad tires can cause shimmies as well.
How to fix: If your tires are worn, it may be time to replace them.

3, Wheel balance
Wheel balance is a significant factor in creating vibrations throughout your vehicle. Your wheels should spin smoothly and free of any vibration when you’re driving at high speeds; however, if you notice that there is a shake or shimmy when you’re driving, this could indicate a problem with your wheel’s balance.
How to fix: Pull towards the side where your wheels are out of balance. If this is the case, you should have them rebalanced.
4, Worn sway bar
Worn sway bars are another common cause of car shake or shimmy, especially when turning.
How to fix: You can inspect this by having one of our technicians place the vehicle in ‘park’ and try to move the wheel side-to-side while applying force to it in a turning motion. If there is movement, your sway bar bushings may be worn and need replacement.
A brake system out of adjustment can also cause your car to shake or shimmy if you have noticed that the vibrations only occur when braking; this may be due to warped rotors or drums.
How to fix: Have them inspected by a technician to determine what repairs are needed.
6, Bad body mounts
If you’ve poked around underneath your car before, you will notice various rubber mounts connect the front of your engine to the frame of your car. Over time these can become worn or loose, causing vibrations throughout your car while driving.
How to fix it: Replacing worn body mounts is undoubtedly a job that may require the services of one of our technicians; however, if you have some knowledge of how to work on cars, this can save you quite a bit of money.
7, Bad engine mounts
Another common cause is bad engine mounts. If any of the mounts that connect the front of your engine to the frame, chassis, or body of your car become worn, loose, or if they break entirely, this can cause vibrations too.
How to fix: Maintaining your car’s engine mounts is similar to maintaining the body mounts. If you notice any loose or worn mounts, have them inspected and replaced if necessary by one of our technicians.
8, Loose driveshaft/driveshaft bolts
If your driveshaft is not adequately balanced, it may wobble and cause the vehicle to vibrate at certain speeds.
How to fix: Your driveshaft should be balanced by a professional automotive technician who can perform this service for you.
9, Bad ring/pinion
When you go off-roading, it is possible to get debris into your ring and pinion gear that will cause an abound-up feeling when you try to accelerate or decelerate.
How to fix: Go on a test drive, and during acceleration and deceleration, attempt to feel the gears move through your gas pedal and a brake pedal. If they feel like one solid piece of metal instead of individual parts moving at different speeds, you may have a problem with the ring/pinion in your rear differential.
10, Transmission problems
My dad had an issue where his transmission was slipping and not shifting correctly. It turned out to be an easy fix after replacing one of his sensors.
Other issues could occur, such as your torque converter locking up while driving which will cause the vehicle to vibrate.
3 Tips To Prevent Car Shake
Look at the tires and inspect them for damage, including worn treads and bubbles. If a tire has a bubble, it needs to be replaced immediately because this could cause an uneven distribution of weight in the vehicle. Tires should constantly rotate every 5,000 to 8,000 miles. Ensure the wheels are attached tightly because this can lead to a shaking car. Another way to prevent car shaking is by checking the tires’ pressure monthly and keeping it at optimum levels.
The shocks on a vehicle can wear out over time and lead to a bouncing motion when braking. For this reason, it is vital to inspect the shocks regularly to avoid car shaking in the future.
People can also look at the vehicle’s suspension system for leaks or loose parts because these problems will cause an up-and-down motion that becomes amplified over rough terrain. If the shaking becomes more pronounced when driving over rough terrain, it could be due to a problem with one of the drive shafts or rear differential.
A car owner should inspect these parts if this is the case and replace them if necessary. Another potential cause is worn ball joints, so checking with an expert mechanic is best to deal with this problem.
Cars that are not maintained well can lead to various other problems, including engine shake. This usually happens when the engine is misaligned or improperly installed. According to auto experts, it may be necessary to have an expert mechanic realign the timing belt and pistons in the engine. In some cases, a significant part may have to be replaced entirely. It is not worth taking the risk of ignoring problems with an engine since this could cause other parts to wear out more quickly.
If an engine shake persists, a car owner should bring it in for a complete tune-up to correct the problem.
