Hey evryone I have a problem an need help I have a2005 fx 35 awd put new front pads an rotors on it cost me 380.00 car still has problem. When I get in the car in the morning an drive car is fine but after like 5 miles car begins to shake bad only does it when something is gettin hot checked front end everything looks fine had it on a lift an put it in drive an the motor shakes tranny shakes when appling the brakes an hittin the gas bought the best rotors an brakes anyone have this proble is it a tranny or differental could a wheel bearing cause this someone said it could be a brake sensor but no lights in the dash are on any help would be great thanks
 
If it's the tranny or diff it's going to do it all the time and not just when hot. It sounds like an electronic problem. If you let the car cool down does it run fine?

Without more info, look at the cam and crank sensor. Look at the plug wires. When the engine is shaking, pull one plug wire at a time. The one you pull that does not make a difference is the troubled cylinder. If they all cause extra shaking, it's not limited to one cylinder and may be a cam or crank sensor.

Faulty electronics can show themselves when hot due to the added resistance. If it's mechanical, it'll be there all the time. Cold and hot.

Say I stop an go in a store for a1/2 hr it wlii be good till I drive down the road some more it's not coming from the motor it's more like a viberation like I'm driving on a flat tire almost it's crazy
 
i only had a problem like that when i had low profile tires and i changed it to non low profile it started shaking, i took the wheels off and noticed round plastic/rubber like rings on the wheel drums e.g to prevent tire shake on low profiles, so i took those out and its fine now, take you tires off and see if u have those rings on the drums of ur car

Those rigs are Hubcentric rings and they are to center the oversize bore on afterrmarket wheels to the FX hub.He won't have those if he is running OE wheels.
 
exactly i had aftermarket 22's and when i put the stocks i had that problem

could one of your wheels be severely out of balance?

I had a bad wobble once. It happened when I was in a small town and it had been raining lots...the gravel roads became muddy roads. The mud dried and caked on everything, including the barrel of the wheels. I decided to wash the vehicle before driving home. It developed a bad wobble afterward. Couldn't figure out why at first, then when I looked inside of the wheel spokes, I noticed certain areas was clean of mud and others weren't. After properly cleaning the insides of the wheels, the problem disappeared...did something like that happen to you? Did you hit a bad pothole and possibly bend a rim? Did some balancing weights fall off? Just brainstorming out loud here. Hope you find the cause soon.
 
If it is doing it only when the vehicle is hot and goes away when cooled down, it is not mechanical. ie If a tire were severely out of balance, it would be out of balance even when the vehicle were cold. The fact you said your problem goes away if it sits for 30 minutes indicates it is a electronic problem.

However, check the tires and brakes if it'll give you piece of mind. At least it'll allow you to start narrowing things down. Check sensors and modules. Wires and plugs.

Can you give more info as to when you see symptoms? You've said when it's warm and goes away if it cools for half an hour. But is it when you are driving at high speeds, under load? City driving, cornering, at idle, etc. Definately need more info since symptoms you've described point to electronics but at the same time there is no code.

... no code doesn't mean it's not an electronic issue though.

This could very well be an electrical problem but a mechanical issue should not be discounted. Lots of things change in mechanical systems as temperatures fluctuate. Solid materials expand and contract, fluid viscosity changes, etc... In my experience, noises/vibrations that vary relative to temperature are much more often mechanical in nature.
 
Thanks everyone for the responce it has been doing it for like a month now an getting worse it got so bad yesterday I got off of the highway. Changed brakes an rotors rims an tires are fine it does it at any speed after driving the car for about 20 mins. This problem occured outta nowhere didn't hit anything ect. When comin to a stop real slow u can feel the car pulsating an dragging a little. At higher speed it feels like ur driving on a flat tire.
 
So it's probably not the front end suspension or steering because if it is you'd be fighting the steering wheel. Next question, sitting still with engine hot, hit the accelerator, does the car shake? or do you have to be moving?

**Just to confirm, the steering wheel is not seesawing back and forth?

If it does shake while in park and revving while hot... you may have a miss. You now need to see which cylinder or cylinders are not firing.

Check the spark plugs... look for water or oil. If you do find it, it could be from the head gasket. If no oil or water... look at the coils, then plug wires. Next look at the sensors, unfortunately there is no good way to check which sensor is bad. The timing is controlled cam and crank sensor which inputs into the computer which outputs the signal to the coils and plug. The sensor and computer portion is hard to pinpoint. Usually the cam and crank gets recommended first since they are cheaper.

These steps are assuming we are ruling out suspension problems. Which is what we are able to do when you rev the motor while in park. It takes the suspension and front end out of the equation. Mostly anyways.
 
A mechanics told me that it's my axle he said there's bearings in the axle an when it gets hot there causing the problem when we had it on the lift the passenger side axle was shaking an wobbling an drivers side was not hopefully this is the problem.
