05 Lancer OZ 90k miles with megan coilovers. its pretty low.

So sence about november I started to get a harsh vibrate when I would decel. It would be so bad that I first pulled over thinking it was a flat tire and it wasnt. So I started driving again and it wasnt there. Couple of weeks later it happened again twice or 3 times then it started to come when I was acceling over 50mph. now it is horrable and feels really bad. when it does this, it vibrates so bad that coins raddle in my car, the spedometer shakes. its unexplainable how bad it is, the whole car wobbles shakes... noticable to all people i drive in the car with.


so about decemberish I replaced a tierod end. I noticed it was bad and the tired could freely move a 1/4 to 1/2 of an inch. it help but was still slightly there. sure enough s week later it was back to the full extent, and the tie rod end was shot again same one. comming from the drivers side. Now im thinking its maybe a barring but im not sure. Theres no indications that it is the baring so idk. Kinda in a hole right now.

I also have a 6 puck clutch with a 2600lbs presure plate.

Im just hopping its nothing from in my ranny

All help with be great Thanks

 

Rotors maybe are warped?

 

does it do it while braking? if it does it while on the brakes makes me think shot rotors. Could also be wheel bearing? jack that side up and spin the wheel see if you hear anything

 

Its not the rotors. its not during braking... and i herd a humming whining noise litterly 83 to about 87mph. witch isnt there anymore but that was it. and the tires spins fine with no noise on a lift. im stumped

 

When you replaced your tie rods, did you get an alignment afterwards? Not doing so could definitely cause the exact issues you're describing.

 

Yeah got it aligned aswell.

 

After re-reading what you posted, it seems I overlooked that you wrote that your issues are happening when you are accelerating and decelerating. Does this only happening during acceleration and deceleration or is it anytime you're moving at over 50mph? If you get up to speed over 50mph and put it in neutral to coast does the vibration still occur?

 

Not really.. When Im highway driving and just coasting.. like steady speed on a flat strip dont feel it at all.. then when i have to go up an incline and have the give it a little more gas to matain speed... it vibrates bad I usally end up slowing down to 60 mph as im making my way up bc it feels like torcher to th car.

some one mentioned maybe a warped flywheel? stock flywheel with the aftermarket clutch... It does feel like something is off balanced.. almoost like there is dirt in my wheel or snow/ice... but theres not

 

This may sound basic but when's the last time the wheels were balanced? Missbalanced wheels will cause alot of vibrations. Prob wouldn't kill the tie rods though. But I just recalled once I had a tire weight fly off while driving and it cased all kinds of shimmy and shake

 

yeah i have done that aswell atleast got new tires put on during that time for the snow but i was considering takeing them off and rebalancing then anyways

 

Does anyone think maybe its a bad motor mount? I looked under my car today and the flex pipe is shot..... and people have said my exhuast moves around alot when I acclerate and when i get going from a dead stop?
