Car Shaking Problems

Vibration at idle, especially with automatic transmission, is usually caused by engine idling to slow. Now, since there is no idle adjustment screw anymore you need to have the vehicle checked at your Toyota Dealer. Some vibration, even to that level is normal. IF IT HAPPENS IN THE PROCESS OF STOPPING, WHILE BRAKING, YOUR BRAKE ROTORS ARE LIKELY OUT OF ROUND.

Usually on a new car the problem is incorrectly torqued wheels. Your owners manual will tell you how to do this. If not, loosen all wheel nuts on one wheel at a time. Then retighten each nut in an X patern.

Try changing spark plugs and wires

If it is not a separated tire, which I feel it's not, because it happens to my '01 Avalon, as well as many other models/years. Immediately after tire replacement, then of course an alignment should then be done. Additionally, I recently received, Oct 2010, a recall notice regarding the replacement of the Steering Column Upper Bracket. Please check to see if your model is included in the recall, as it is very important to have the repairs made, to avoid a possible crash.

it could be your engine mounts are needing replaced

You fail to list what vehicle, and how severe it is. So, I can only tell you that if you have a car with an engine developing quite a bit of horsepower and it is front wheel drive, (FWD), you may be experiencing what is commonly referred to as Torque Steer. Torque steer is common in FWD vehicles with high output engines. Some worse than others. Depending on the severity of the torque steer it may be normal or it may not be. Make sure that your tires are at the proper PSI as listed in your owner's manual and on the driver's door post. A slight amount of torque steer is normal, but you may want to have a professional evaluate if yours is above normal, and you have a problem.

You have warped rotors. They will need to be removed and trued or replaced. Causes of this are lug nuts overtightened, or heat from heavy braking at high speeds.

The spark timing might be too advanced. At high temperatures and RPM an advanced spark might cause preignition, and engine knock. That's only likely to happen if the engine is modified though.

Other than that, check the air and fuel filters are clean, as the harder the engine has to work the more a clean flow of both is important.

you need the brakes bled,not bled right.you have to bleed all four wheels. 65;

Bank 2 is the drivers side of the engine on a Ford Expedition

Sensor 1 is in the exhaust , close to the engine , before the exhaust enters the catalytic converter ( upstream )

There is a large amount of leaves or pine needles in the blower wheel. It most likely gets worse the higher the blower setting, the faster it spins...........

i would start by having tires checked and then balanced and wheels checked for trueness, if that doesn cure issue could be the alignment, a bad wheel bearing or worn suspension components

Timing belt. misfiring engine

There is a numerous number of reasons. It can be the fuel filter, can be the air filter, can be the knock sensor, might be faulty spark plug wires. You have to check all of it.

If you have a diagnostics tool it can simply your life a lot because some of them are capable to show voltage in different parts of the car and also other parameters which can give a hint about the situation.

If it only happens when you accelerate the most likely cause is an axle.

For the brakes, check for warped rotors.

For the turning, check for worn CV joints.

Need some more details. Vibration all the time? Only certain speeds, only when you accelerate, vibration in the steering wheel, in the whole vehicle?

This could be the cause if an improper alignment if it happens under normal straight line driving. If the jerk is more prevalent when going on bumpy roads, it may be a sign of bad shocks or springs. If the jerk is occurring during braking situations, the problem may be related to the bearings being worn or warped discs/drums in the braking system.

most of the time bad allignment or not balanced tires. You could also have a bent rim.

You have warped rotors. Have them turned at machine shop or replace them. Also replace the brake pads.

Tire out of balance, bent wheel, drive shaft bent, loose or worn steering parts.

the three things to inspect on a car that shakes at 50 mph are, tie-rod, lower ball joint, and tire balance.

lift your car so the front tires are off the ground and grab the tie at 3 oclock and 9 oclock position. try to move the tire left and right. if there is play have someone inspect the tie-rod while you move it back and forth. also check wheel bearing and lower ball joint.

if everything is tight, have your tires balanced and rotated

It senses whether your crankshaft has packed up, and if so, warns you of such. Driving without a crankshaft is dangerous! It can lead to not going anywhere fast, and is often a sign of owning a Chrysler product.

The Crankshaft Sensor communicates to the computer what position the motor is in so it can fire the appropriate spark plugs and fuel injectors in a continuous cycle, or firing order.

replace front brake rotors and pads.

You have a tire out of balance, bent wheel, or defective tire. Have the tires inspected, rotated, & balanced. Make sure they inspect the wheel. If that does not solve the problem you have worn suspension or steering parts. After all this vehicle is 14 years old.
