Most likely, one of the engine mounts are 'torqued'. You can try and neutralize the mounts. Loosen the through bolts of all mounts several (4-5) turns. Then start the car, and drive back and forth several feet (using quick taps on the gas and not just idling) over and over, and let it rest at idle a few seconds before turning off the engine. Now tighten all ...

Vibration felt in the steering wheel is usually caused by the front tires out of balance. That's the first place to look, other possibilities include: broken belt in the tire, out of round tire, a bent rim, a bent or out of round hub, wheel bearings. One of the things you can do to help narrow it down would be to rotate the tires, if the vibration in the ...

In my experience, Polyurethane bushes last longer than standard rubber ones, as the plastic doesn't perish in the same way that rubber does. As you mention, there is a price to this, as they are generally harder than the equavalent OEM bushes, however many manufacturers offer a variety of stiffnesses, depending on the intended use - some of the softest ones ...

If "injector cleaning" products helped but only lasted for one tank, I would try spraying Seafoam directly in at the throttle plate rather than putting an additive in your fuel. This should be a lot more effective at cleaning the injectors. If that doesn't help, my best guess would be that the vibration is from unequal power from one or more of the ...

There are a few possible things which could cause vibrations: When breaking hard, your discs could take up some heat and get warped, great article could be found here. Bad geometry could cause vibrations + uneven tyre wear (flat spots maybe?), see related article. Check wheel balancing, article here. I would recommend to check these first, there are ...

Tires are out of balance, or possible a bent rim. Take it back to where the tires were put on and tell them you have a vibration. If you have a vibration when you are using the brakes that goes away when you take your foot off the brake you may have warped rotors. I would take car of the tire balance issue first before addressing the rotors. You may only ...

I've had very similar sounds from a bad wheel bearing before. For a 2008, that would be an early failure though. Not likely, but if you rule out the other items, check the wheel bearing play/feel.

The noise you are describing is likely the wear indicators on the brakes. They are small metal tabs that come in contact with the rotor when the pads nearly gone. It's designed to let you know that your brakes need to be changed. You mention that you just replaced your brakes, did you do all four wheels? It might be the lack of shims, or disc brake quite on ...

The vibration at speed is very unlikely to be the alignment. I would suggest getting your tires balanced. The most likely cause is that one is slightly out - perhaps a tire-weight fell off, or the wrong weight was put on last time you changed tires. - Bad alignment will eat your tyres faster than good alignment, but if all the shops you have been to say ...

Did you check the inner and outer tie rods for play? How are your ball joints and bushings up front? Were all of those inspected when getting the alignment?

Sounds like the Idle Air Control Valve and the Intake Manifold must be removed and cleaned. The vibration is worse when in gear than in neutral In gear there is a much greater load on the engine. Power is being transfered to the transmission and then to the wheels. This is going to cause the idle to drop a bit and this is where you'd feel the most ...

I also have a AWD Trailblazer, and low diff oil can cause uneven gear wear (mine is perennially low because I have a leaking diff seal which the dealer can't get out). As the oil heats up, the vibration can become more prominent because the thick oil is no longer damping the vibration. You may also want to check that your wheels are balanced. You might ...

The vast majority of vibrations that come and go at various speeds are wheel and/or driveshaft balance issues. They come and go due to exciting the suspension/steering when reaching resonant frequencies. Yours may be a wheel issue that shops would rather balance as well as they can than tell you you should replace a wheel. There are more expensive ways to ...

You replaced the engine mounts? I would guess that since you had to change the engine mounts that there is a good chance that the tranny mounts may need to be changed as well...what is the drivetrain assembly like in that car since it is fwd, sometimes if the driveshaft in a rwd car is unbalanced it will cause the car to shake

I had a bad vibration when cruising on highway, I did an alignment and changed my wheels bearing. The vibration was mostly gone but I got a "death wobble", which is a loud noise coming from the front at high speed. I changed my tie rod ends and steering damper, redone an alignment and now everything is fine. I'll do what Larry suggest first, this are the ...

It can be very difficult to isolate if it us from the tires or the drive line.. but most of the time, it is the tires. Looking at the ties with the naked eye when there is no load on the tire is not very telling though. The best thing is to find a shop with a Hunter DSP 9000 or similar machine that measures so called road force. This will measure the tire ...

I would have commented but this is a little long. I suspect your vibration's behavior at higher speeds is more along the line of frequency rather than vanishing. I've had numerous of these situations and really it gets down to pinpointing the vibration with some good friend(s) that will go along for the not-so-fun troubleshooting ride. I would not assume ...

This could still be caused by your wheel(s) being out of balance. Two things you can do to see if it is still your issue. First, take it somewhere they can balance your tires for a higher speed. Sometimes the "normal" balance is not quite enough to get them right. If you get the tires balanced for something over 70mph, it may help your issue. Secondly, ...

Does it make the vibration when in park? If not, I'd suggest you may have a vacuum leak after the throttle body or possibly your Idle Air Control (IAC) valve is not functioning correctly. If you are not experiencing any rough running at off idle, it has to be something which would only affect it at idle, or it could be slight enough that you are not feeling ...

Is the radiator overflow tank properly connected and sealed? Overheating can be caused by the low coolant, caused by the radiator leak. Expanding coolant would expand out the hole in the radiator making the problem worse. Repairing or replacing the radiator would fix that. Overheating can also be caused by a blockage in the coolant passages, which would ...

Firstly discs do not warp.Pads contain metal that deposit on rotor so when measured in a number of places it is assumed the disc is warped.Check balance weights on rim have not fallen off.Jack up front wheels one at a time;grasp tyre each side of centre and pull to and away from you.Any noise or movement may indicate that tension on bearings is incorrect

If this is a Jimny, then this is sadly expected. There are stories of people replacing the gearbox mount to resolve the issue, however I never got that far with my Jimny. I had replaced a number of bushings, got an alignment, and new alloy wheels, however the shaking was still there - just far less pronounced. Like you, the vibrations were fairly violent at ...

The groove could simply be a bit of dirt stuck there and I doubt it would generate the noise you describe (although getting rid of it is ideal). Based on the fact that the pads are thinner at the top than at the bottom and that the noise comes and goes seemingly at random my guess is that the corresponding calipers are getting stuck on their grooves for some ...

You have new brakes it takes time to them loose the original coating/surface. My have the same problem for a time but not lasted for this long. The grove is does noot sounds good. If they are not too deep you could go to a shop and they could make resurface it. Sometimes your disc soo thin that they could 'bend' because of the heat. Is this sound 'still' ...

It's probably just the new motor mounts. If the new motor mounts are stiffer you will get more chassis vibration. I am a little surprised that shifting to neutral effects the vibration though. Is it automatic? Did they have to drop your transmission cross member or any drive shafts during the service. If so it could be something to do with that.

Check your car engine seat as this could cause steering and dash board vibration.

I fixed the vibration problem I had for 1 year on my 2007 toyota camry after I cleaned the throttle body and air control valve (iac) the car is driving perfect. I can not believe it was so easy to fix...

Based on your information, it appears your transmission is on it's way out. If your mounts were bad and the car was driven for a lengthy period of time, you were putting more stress on the tranny than usual. Being a FWD car with the tranny on the side, Horizontally opposed to the engine, it's verifiable when you say the car "shifts" when turning it off. This ...

I have had this on various occasions on all my Subarus once they get old, and on my Forester STi at only 70k miles! Polyurethane bushes on the much harder STi suspension last less time than rubber - it seems they are so hard the impact transferred to them is higher (have to replace every 25k or so - but this one is set up for track, despite being my ...
