It sounds musical, but what it really does is disperse vibrations that travel through the crankshaft to prevent damage to it and other vehicle components. The harmonic balancer, or vibration damper,...
When it comes to important components in your vehicle, the driveshaft holds a lot of importance. This part is responsible for delivering the torque, or power, that is being made by your engine...
Hello, thank you for writing in. Feeling steering and suspension issues in the steering wheel is very common. While everything you have done is within reason, there are several components that need to be inspected or tested. You will want...
It could be that one or more motor mounts is getting tired. The Motor mounts are rubber to metal brackets, some of them have fluid capsules and they keep the engine in place while isolating the car from the normal...
A possibility is the motor/transaxle mounts are worn or sagging and that causes misalignment of the CV axles accounting for the noise and vibration. However, that is just one possible scenario. Vibration under acceleration could also be due to an...
If the vibration occurs without braking, common causes of the vibration you are describing include wheel bearing faults, wheel/tire assembly imbalance, defective tires, and perhaps a stuck brake caliper. Other, less common possibilities include suspension faults (strut/shock failure) and even...
If there were a fault with the control arm (bushings, ball joint, etc.), or ANY component of the vehicle suspension, it would have been literally impossible to perform a wheel alignment. Alignment tolerances are measured in the tens of thousandths...
Of course, be sure any required maintenance has been performed. YourMechanic can assist with maintenance. For example, if the spark plugs have not been replaced as required that alone can cause the hard starting that you are reporting. Other causes...
Hello, Most of the time this is caused by an issue with one of the accessory pulleys. Most of the time it is the water pump due to an internal bearing failure. I usually pull the belt off and turn...
The required repair will depend on whether the vibration is suspension related versus engine related. If the tires are vibrating, there might be a wheel imbalance, tire defect, or suspension fault. If it is the engine vibrating, typically the cause...
Hello thank you for writing in. There are several components that you will want to have looked at. Regarding the wheel bearing, they do cause similar symptoms, and if you hit hard enough, you will want to have them inspected....
Hello, thank you for writing in. This is going to be a process of elimination. You want to start with the simplest fixes which include balancing, aligning, and properly inflating the tires. From there, or during that process of removing...
If your car is misfiring, the Check Engine light should be on. Unless it is not working.There are some other possibilities which would not turn on the check engine light, but without driving the car it's very hard for me...
Hello, thank you for writing in. The vehicle may be suffering from several different issues. In this type of situation you want to start with the least complicated option, and work your way up. Start by making sure your tires...
Sometimes there are multiple causes, or sources, of vehicle vibration. Based on your description, the vibration might be due, at least in part, to faulty motor mounts. To check for engine-mount problems, you can try shifting from "neutral" to "drive"...
Hello, thank you for writing in. When dealing with these types of situations, start with the simplest possibilities, and work your way up in complexity. Start by having the tires balanced. Make sure you have not lost a wheel weight,...
Hello. It sounds like you may have a failure in the drive shaft or possibly an engine misfire. If the engine is running rough then it needs to be checked fro any misfires or engine codes. If the engine is...
If the driveshaft was rebuilt, I would first check to be sure that the shaft is balanced AND true. The biggest problem though is identifying a facility with the appropriate CALIBRATED equipment and knowledgeable staff. If you can identify a...
Hello, thank you for writing in. The vehicle is likely having an issue with one of its three main components: air, fuel, and spark. Most vibrations and shaking come from a misfire of some kind. You will want to check...
Vibration at speed is usually due to dynamic imbalance of the wheel/tire assembly and/or a rim is bent. Even stronger vibration on braking can mean that the brake rotors are warped as well. Certain tire defects, particularly internal belt damage...
If the struts are defective, that can be a cause of vibration. It sounds like the struts have to be replaced anyway, so I would suggest doing that first. Check the exhaust system (is it all OEM?). Check for damaged...
Hello, thank you for writing in. If the issues started after the work that was most recently done, you want to verify that those repairs were done right and are holding. If the vibration and shaking were present before hand,...
