So, you first noticed it after you aired up the front tire, that's probably just a coincidence, tire tread or belt and bearing problems would make their noises all the time, not just on deceleration as you stated. Tire ballance issues will get worse at a particular speed, if you were to accelerate thru that particular speed fairly quickly, you might not notice the noise or shaking, but as you decelerate thru that speed, or decelerate and remain at that particular speed the shake / wobble can get larger, especially if tie rod ends are bad. Then it can stick around till you're almost stopped, once you resume moving the cycle can start all over again.

The other thing could be motor and tranny mounts? maybe as you decelerate the motor is twisted an inch or two within the engine bay, this twisting could allow drive line to contact suspension peices, all wheel drive would add more resistance to the deceleration twisting or torquing than would two wheel drive!

Lastly, duct tape or ziptie a digital camera set to video and get some footage of a few suspect areas as you drive, video and sound would be great, you might have to try it a few different spots, but this might give you some answers.

Or take Sams advice, and just pull the trigger on it!!!

Well, My car does need an alignment, And the front right tire is pretty much bald.
Could it just be the tire?

Yes. You can part swap all you want but your car isn't going to drive right till you take care of the wheels and tires.

Yeah, it could be just the tire, but I don't feel it would only make noise or shake on deceleration only, seems like it would do it all the time, and just get worse as speed increases along with centrifugal force. It could be that you're feeling multiple effects from multiple problems?

I know some of these other guys are sharper than I am, maybe they'll drift back into this thread for you?

It's a consistent thing. It happens while My foot is on the peddle as well, But 90% of the time it happens when I take it off. The brake's holds no factor in it shaking and such as they do not trigger it.

Ok....well, what about your brake rotors? Are they warped?

Nope, Not the rotors.
I'm taking it in next week to get the tire fixed and an alignment.

without driving it, there are a couple of things:
does it pull really hard?
when you hit the brakes, does the car dart to one side or the other?
is there a clunking noise coming from the front of the car while turning or hitting bumps?
is the shaking in the steering wheel or seat?
is the shake consistent, meaning is it the same shake at any speed or does it occur at one particular speed... i.e. 40-60?

it could anything from a bad rack to a bent wheel... i'll tell you this, you STAND THERE AND WATCH THEM LINE THAT CAR UP. Do not, I REPEAT, DO NOT let that car from out of your site during the alignment. Make sure he checks the suspension steering components individually. If you have any common sense, you'll know what excessive play in the front end looks and sounds like. Some alignment places are as shady as they fucking come.

So it was finally discovered to be the ball joint, if anyone was wondering.

Posted by Caligula So it was finally discovered to be the ball joint, if anyone was wondering.

did you replace both sides?
and did you check the tie rods/tie rod ends?

Posted by Samurai did you replace both sides? and did you check the tie rods/tie rod ends?

I brought it to a mechanic, I believe he only did the one side and The tie rods/Tie rod ends are in good condition.

I did get the ball joint replaced,An alignment and my tires rotated tho, All for $175.
