Car Shaking Problems

Car shaking problems are usually the results of mechanical problems. Out of adjustment tires or suspension will make the car shake after reaching a certain speed. Warped brake rotors will also make the car shake when it’s slowing down.

How do you stop mirror vibration on exterior power mirror for Chevy z24 2000?

pull the plastic piece on the inside of the door that is triangle shaped on the reverse side of the mirror. there will be 3 bolts. try tightening them

What would make the rear tire of a 1998 ford expedition wobble?

The tire could be faulty, the wheel bearing could be bad and need replaced, the wheel could be bent.

Why does your tire wobble?

If you mean it's running "untrue" at low speed, it's either a bent rim or a "slipped belt", meaning that the internal structure of the tire has a problem.

Your Car shakes when AC is on what could it be?

Is it a 4 cylinder? Sometimes a 4 cylinder engine will shake a little extra when the AC is running and it's at an idle. You might be able to step up the idle a little extra but 4 cylinder engines are notorious for shaking when the AC is running.

Why while accelerating from a stop an automatic car would jerk as if stepping on the gas and letting go repeatedly?

Either you are low in transmission fluid or the transmission is slipping. Take it to a well qualified transmission repair facility.



Another possibility is the Throttle position sensor is bad. when the vehicle is off, locate it, it will be on the throttle on the other side of the housing from where the cable connects. you can unplug this and use an ohm meter to check I believe the outside terminals while opening the throttle slowly. If at any time its open the ohms increase or go over the limit then the switch is bad and it sends a closed throttle signal to the computer which cuts off the fuel supply to the engine which creates a bump feeling, or a jerking.

What will cause a car to shake if it has new tires new rotors and new drums?

It sounds like the tire or tires are improperly balanced. That is the most likely answer, though it could be other things, too.

When you hit a bump it feels like the wheel is going to fall off?

Do you have good ball joints and good shocks/struts? Are shock absorbers in good condition? Are any radius arm/strut rod bushings in good condition? Are struts and strut mounts in good condition?

What does it mean if your car is shaking violently at 50 MPH?

My steering wheel shakes what could this mean?

_____

try getting your car re-aligned.

What is the problem when your car jerks and not pick up speed?

The problem could be the starter. It's tough to say without seeing the car. The best option would be to bring it to a mechanic, who could correctly diagnose the problem.

Why do my brakes vibrate so bad when I stop on my 1997 Volvo 850?

Vibrating brakes are almost always a symptom of worn rotors. When the rotor wears down, or has grooves, the brake pad can no longer make a flush connection with the rotor. This will cause the caliper (which holds the brake pad) to move in and out as it tries to establish a flush connection with the rotor. The rapid movement of the caliper is what causes your brake pedal to vibrate.

Why would new tires shake at high speeds even after balancing when they didn't shake before?

Usually when new tires are installed, they will be put 35 psi of air pressure in them. Look at the label inside the drivers door to see what tire pressure your manufacture recommends for you vehicles suspension setup, and then check your tire pressure. If lower tire pressure will dampen the shake, then it is an undesirable product of the vehicles design.

Then again, I have had carelessly installed balancing weights fly off a tire before. If this happens to a front tire, it will be much more noticeable, especially if it was a large weight that was used to balance the tire. More information would help, vehicle make and model, number of doors.

If tires shake after a new install, there are quite a few possibilites. These are the most common. The car needs to be taken back to the place of the install and all tires spin checked on the tire balancer for a good smooth roll and perfect balance. If by chance you bought the lower price tires they sold you may have out of round tires. This makes the tires hop no matter how well balanced, and they will shake until they are turned on the wheel to cancel the "bad roll". This doesn't mean you have bad or defective tires. You have to understand that all wheels and tires have a high spot on a 360 degree circle. Nothing is perfectly round. On problematic tires this can be fixed. If the appropriate measures when taken to cure the problem, and it didn't fix it....That tire must be replaced. Full warranty of course. This happens with Michelin and some other top brands...not just your cheaper lines. If you have custom wheels, these require two plane balancing with sticky weights. You might need a more qualified shop to cure this, as it gets tricky. With fancy wheels, find a good tire shop and stick with them if you have good experiences with them. Rotate every 6,000 miles religiously! Some people do more often and some less, but with 6,000 you can't go wrong and will have decent life and tire wear. Combine this service with oil changes to save time and money. Change your oil every 3,000mi and rotate your tires every other oil change. You can't go wrong with those basic rules. Good Luck!

Why does the check engine light flash when accelerating and the car sputters and jerks?

AnswerA flashing check engine light means that something serious is wrong with the vehicle and you should not be driving it. Being that the vehicle sputters and jerks under acceleration, I would assume that you have a failure in your ignition system. Always have the car scanned when your check engine light comes on to obtain diagnosetic computer codes. Most common failure is basic maintenance items, Spark plugs and wires. Simple enough to replace, and relativly cheap. Ignition coils, ignition module, and crankshaft sensor would also cause a severe misfire. again... both pretty simple to change, but these items cost more. Start by having the vehicle checked with a scan tool first.

I had the same problem. It was the timing belt. If your Miata has around 100000 miles on it and the belt has never been changed it's most likely it. Timing belts are expensive to replace. You can change it yourself and save a ton of cash but be prepared to spend a few days working on it. Check out the Miata fan sites for step by step instructions!

What can be wrong when your wheels just got balanced and aligned and the car still seems to shake?

Many factors can contribute to shaking in the front end of a vehicle; and, although an alignment coupled with balancing the tires diminishes the possibility that the components involved in these procedures may cause this problem, they are not altogether eliminated from suspicion. Let's take the tire/wheel combination. The tire/wheel combination can be balanced with something inside. If the valve stems were replaced, and the old stem was removed with the tire mounted to the wheel(but 'broken-down'), the possibility exists that a portion of this old valve stem fell into the tire when the stem was pulled out of its hole; and, the small portion inside will roll around until it reaches the same speed as the rotating tire. This is how the tire is then balanced. When the wheel is subsequently installed onto the car, with the balancing weights affixed to the rim, the small rubber stem-bottom is rolling around inside the tire. Now, when the tire rolls down the road, not only is it improperly balanced, but that little rubber gremlin adds to the problem by again moving all around until it begins to spin at the same speed as the tire--- at which time it is nowhere near any point which would balance the tire. The only cure for this is to break the tire back down, remove the rubber remnant of the valve stem, remove the balancing weights, air the tire back up, and re-balance the tire/wheel combination once more. Other possible causes have missed notice on many occasions: A separating tire, a bent wheel, an out-of-round tire, a badly seated tire, and a tire/wheel combination into which tire sealant(Fix-a-Flat?) has been introduced. Tire sealant is particularly notorious for leaving a pool of liquid inside the tire, causing much the same problem as the valve-stem scenario, but without the telltale noise of something rolling around inside when checked. This stuff has to be sopped-out of the tire with a towel. Only then can the tire be properly balanced with the rim. If the tires, wheels, and tire/wheel combinations are in good shape, an alignment can be performed--- if the suspension and steering are tight. This brings up a point: An alignment is an adjustment procedure. The purpose of an alignment is to restore the steering and suspension geometry to the specifications found by the engineers of that vehicle which provide the optimum compromise between handling, stability, control, and wear factors. This is achieved at a specific loading of the vehicle, at a specified ride-height, with a certain amount of gasoline in the tank. An alignment may also be performed on a vehicle which has suffered some types of damage which necessitate attention be given to the rear axle areas as well as the front. This introduces the four-wheel alignment and the thrust-alignment. While settings exist for effecting corrective measures where geometry can be adjusted back into line, no bent part is usable if found: It must be replaced. Much inspection, therefore, is given to parts when an alignment is performed; but, some things are not always clearly evident. When weak struts which cause a vehicle to bounce are found, the finding is usually presented to the customer, who makes the decision for or against replacement. These WILL cause tire wear; and, the cupping of the tires can cause the front end to shimmy. When tie-rod ends are inspected, they may not be loose; but, on rack-and-pinion steering, the inner tie-rod-ends often go undiagnosed as a culprit until a customer complains. At this point, a good technician can find the wear and know the customer will not feel harassed by the news. Lower ball-joints usually require a procedure to be used whereby the joint is 'unloaded' in order for wear to be determined; and, this takes time--- time many customers do not have. If there's nothing outwardly evident of joint failure, the joint is given a visual once-over and a cursory tug at the edge of the wheel. If no exotic movement is felt, all is okay--- until the customer complains. At this point, the customer has the time for the inspection; and, they are ready to make repairs. As far as control-arm bushings, much the same can be said. Ditto for sway-bar bushings. As far as connecting links for the sway-bar ends, these are visual; and, when a customer can be shown the wear, replacement is forthright. Literally, anything which is loose or worn to a certain degree that otherwise should be 'tight' in the suspension or steering can cause a shimmy. This may be observable by routine inspection or special inspection and testing. Some problems may be remedied through low-end replacements, while some may be costly. If CV-joints are coming apart, allowing the shafts to rotate in an orbit rather than concentrically, money is involved. If front wheel bearing assemblies are needed, money is involved. If a lower steering sector has a worn sector-shaft bushing, money is involved to replace the unit. If a couple of shocks are needed, the money expended is less. If the shimmy you feel is only at the times when you apply your brake, this should be conveyed to the detective(mechanic) charged with finding the problem; because, while YOU know this as a 'shimmy' in the front-end, HE knows this as 'pulsation' from warped BRAKE rotors being transmitted to the steering. In this case, a little extra in the way of communication can save a lot of time and inconvenience; and, your car will receive the proper attention sooner.

Do you have to replace timing chain on Lincoln LS?

If the timing chain on your Lincoln LS is worn out then it should be replaced. A worn out timing chain can jump a link, or more, and the engine will ultimately not be able to run. Normally the timing chain will last the life of the engine.
