Car shakes during acceleration?
If a car shakes during acceleration the brake rotors may be damaged. If the rotors are damaged they will be unstable as the tires rotates making the whole car shake.
How do you change the spark plugs in a Lexus rx300?
Thanks to Vinesh at Club Lexus : I am posting his hard-work here for the benefit of everyone here,...Fortunately, I landed-up there after not finding very useful answer here.
Without further due, here is his posting with awesome pictures for clarity.
I recently spent the better part of a Sunday replacing the spark plugs on my parents' Lexus RX300. I took some pictures and thought I would put together a short guide to add to the information already out on the 'net.
On a scale of 1-10, I would rate this job an 8, but it might be much easier for a seasoned professional or if you have exactly the right tools. Anyway, dealer charge for this job is $330 (parts + labor) so it is well worth doing yourself. I have written this DIY guide with the goal of making the job accessible to beginners, so if anything seems redundant, that's why. Thanks to the ClubLexus thread on spark plug replacement for helping me do this job.
1. Buy replacement spark plugs. I bought Bosch Platinum+2 plugs for about $4/apiece from an online parts store, but from what I've read, the Platinum+4 are much better. They provide much more complete ignition and offer a noticeable improvement in mileage. One anecdote I heard was a friend of a friend who went from 20mpg to 24mpg on his BMW 3-series. The platinum+4 are only $1 more, so the possible performance improvement is well worth it.
2. Get your tools.
3. Remove the engine vanity cover by removing the three bolts near the base (front) of the engine. You'll need a hex wrench to get these out. See the picture below for location. Once the screws are out, rotate the Lexus logo 90� and the cover should come off pretty easily.
4. Practice removing one of the easier spark plugs in the front.
5. First, disconnect the electrical connector from the spark plug tube head by pressing the end with your thumb and using a flat-head screwdriver to pry the connector off. Remove the spark plug tube screw using a socket wrench or equivalent. The tube should now slide out. See the picture below for reference. That was practice, now put it back in and replace the screw holding it in place.
6. Clean the area around each spark plug tube using a hand towel, pressurized air canister, or both. This includes the spark plugs behind the intake manifold. This will be tough because you will have to work by hand, but it is important.
7. Start by removing the most difficult spark plugs - in this case, the back ones. It is better to do the easy ones last, in case - for some reason - you give up or can't get the back plugs out. The back plugs are located behind the intake manifold (see picture below). You'll have to get to them through the opening indicated by the '''blue arrow. You can make this more accessible by removing what I think is the cruise control bracket. Loosen the nut indicated by the '''yellow arrow and remove the bolt indicated by the '''red arrow. Warning: these might be very tight.'''''''''
8. Repeat step 5 starting with the rear right spark plug (rear right when facing the front of the car), followed by the rear center, then rear left. When removing the spark plug, be sure not to let any dirt or debris fall into the engine. It could cause sever damage. The best thing to do is to remove the old spark plug, briefly inspect it, and immediately begin installing the new spark plug.
2006 Malibu LT - V6 the steering wheel shakes when I start it up what could that be?
Could be that the steering wheel rubber bushing is worn or lose. This bushing is located in the engine compartment, between the end of the steering wheel coulomb and the steering wheel likage...Tom
What make a car shakes when it accelerates over 40mph?
The most common cause is a tire out of balance. It can also be a bent wheel, defect in a tire, worn steering or suspension parts, bad wheel bearing, broken motor mount, or CV joint failing. Have your tires rotated and balanced and all steering and suspension parts inspected. If they find no problems then have it looked at more closely by a trusted mechanic.
What is the problem when your car steering wheel vibrate?
Normally it is a tire out of balance. Can also be a bent wheel.
Your 18 wheeler truck steering wheel shakes and knocks when you get at 40mph what is causing it?
There are a number of possibilities:
- Poorly balanced, out-of-round, or bad mount steer tires
- Mud, dirt, or other debris accumulation on the rims
- Out-of-round brake drums making infrequent contact with the brake shoes
- Worn kingpins
- Loose tie rod ends
- Worn wheel bearings
- Worn Pitman arm
- Worn drag link
- Misaligned steer tires
What would make a steering wheel shake between 50-70 km?
If your steering wheel shakes between 50-70 km, it probably has nothing to do with the steering wheel! It probably has something to do with the front wheels, alignment, or steering linkage. See if a front wheel has uneven wear. See if a piece of rubber is torn or perhaps missing. Take it to a place that sells tires and alignments. They will be able to spot the problem.

If the vibration is confined to a certain speed range, the most likely cause is an unbalanced wheel. BTW, the units there should be km/h. Km alone is just distance, not speed.
I would suspect you are correct. Replace all vacuum hoses under the hood if the vehicle is over 10 years old. Otherwise find the leak and repair it.
What causes bad vibration in a ford mustang at speeds of 55-65?
Tire out of balance is the most common cause. Have your tires rotated and balanced. Make sure they check all wheels to make sure one is not bent. Check the tires for a defect in the tire such as a broken steel belt. Inspect the suspension for worn parts. If you see abnormal wear, such as on one side of the tire, ask for an alignment.
I have been running Castrol Syntec 20w50 in my Altima for 15 years, and have not had an oil related problem. The car has 230K miles on it.
What would cause a car to jerk really bad when putting foot on the gas?
When a throttle cable is too tight any slight tap on the gas pedal could cause the car to jerk forward. The throttle cable should be adjusted to allow more play on the pedal.
What is happening when a Nissan Pathfinder is shaking when it is being driven?
You ran over another one.
What would cause a Honda odyssey steering wheel to shake when driving?
I have found that the brake rotors are warped. Why, it could be a number of causes. However, I recently had mine turned for 15.00 ( Did the other work myself) and the vibration has gone away. Now I need to work on getting the suspension tightened back up. Hope this helps.
check cv axles.
What could be wrong if your car is only running on two cylinders?
the first thing that comes to mind is ignition system faults. Are the spark plug wires connected properly, in the right firing order? Has work been done on the distributer, or the engine head, recently? Ignition timing can be 180 degrees out, and the engine will still run, sometimes. If it is not the ignition system, the next most likely culprit is the head gasket, which seals the head to the block of the engine. If this gasket is breached seriously, it can cause a cylinder(s) not to fire. Is there water in the oil, as evidenced by a thick, white foam? Is there oil in the coolant? Either of these are symptoms of a leaking head gasket.
Tire out of balance, bent wheel, or defective wheel bearing are common causes.
Tire out of balance, bent wheel, or defective wheel bearing are common causes.
Why is 1995 Ford Taurus shaking at high speed above 60 mph Wheels have been balanced no improvement?
Check for a bent wheel, defective tire, broken motor mount, defective CV joint.
How do cars cope with high speeds?
When your not looking and close the garage door they drink lots and lots of Absolute Vodka!
Lots of factors are involved. Overall shape of the car, the suspension and tires. cooling system, motor. While most cars will go faster than most people are willing or capable of driving, a car that is intended to go fast is designed for it.
What causes your steering wheel to shake when you hit a bump?
Worn steering or suspension parts. This can be very dangerous, so have this repaired ASAP.
Does bad gas make your car run rough or shake?
It sure can. In some cases your car will not run at all. Normally bad gas just means it is contaminated with moisture. A tiny amount of moisture and your engine will miss and run rough.
What can cause a car to sputter while in gear but not while in park or neutral?
There are a couple of different things that can cause this. On older and newer cars, it can be a worn or weak fule pump. The pump puts out enough gas while the car is idleing, but doesn't put out enough gas for the increased consumption when it is in gear. It could also be caused by the screen in the fuel tank being clogged or dirty, not allowing the gas to flow freely. The same for the fuel filter, an inline or carburetor filter could in need of a change. On newer cars, there could be an inline filter but there is also a filter in the gas tank. Also on cars with fuel injection, the jets could be dirty. There are also sensors on the newer cars that can cause this. They are the MAPP sensor and the O2 sensor.
From your description it sounds as if it MAY be your tires. When sitting for a long period of time (overnight) some types of tires develop a 'flat' spot which causes a shaking sensation when you first start driving the car. As the tires warm up from driving the flat spot goes away and the shaking disappears. Just a thought. Good luck. I have a Ford Focus myself and this happened to my car I replaced My Spark Plugs and Wires and it never came back. Try that.
If that doesn't work it could be something more serious. You may need a full tune up, or you may be suffering the effects of a factory defect in the engine mounts. My son's 2000 Focus had the same problem; a vibration when the car was cold that would go away after about 20 minutes of driving. The dealer replaced the front motor mount and the vibration was eliminated.
Ah, well, see....
When you drive the car, the wheel spins. It is attached through a round thing, called a bearing, to a rigid object called a spindle or a knuckle. The spindle has to be able to move up and down to allow for bumps in the road and if it's a front wheel (or rear wheel with 4 wheel steering) it has to be able to turn for steering.
The spindle is attached to the vehicle in at least three points to hold it steady. An upper control arm attaches to the spindle at the top of the spindle and keeps if from moving in a left/right direction. On some (but not all) vehicles it can also keep it from moving forward/backward and can push the spindle down and car up. It is usually attached to the spindle via a ball joint.
