Vibrations still

[ArtMan]

Hey,


So this has been a battle with no end for me. I had a vibration in the steering for a bit now and decided to buy the ebay( seller deutschepartsusa) fake german kit and first sign showed very tight but on left or right turns i had horrible shaking which was due to faulty lower control arm bushings...so replaced with Febi brand new low control arms and well the shaking went away except for at 80 mph i have a shudder so after new lca i still have this problem i then took my rotors to have then cut to make sure their also even and arnt the source of the problem but my pulse feel went away and no more shaking when braking at like 50mph so that was fixed but at 80 i still have this shudder.

I was told by the guy cutting the rottors that it could be the wheel bearings if i still have some shudder while driving without braking or warped discs.

I just want to have some opinions from ppl who have delt with warped discs to bad CV joins that can cause a vibration. Its just getting really frustrating. I just did a full A/C overhaul wiht new everything except the evap.


TIA

check tire pressure!!! and the wheels themselves maybe you caught a pothole and the rim is bent. that would cause vibration when accelerating or braking. my problem though is that when i turn left or right at low speeds it seems as if wheels catch onto something and it clicks and vibrates? i dunno underneath everything is rock solid fluids i\are at top also! anyway check tire pressure

Well the tires are less then a month old and were new and balanced. I also had them swapped from front to back and no difference.

Do you feel it only when braking? if not leave the rotors alone. how about the long tube(sorry don't know name in english) that travels from tranny to TC. it has teeth that might be worn out.

Well my rotors had lines on them bc of the cheap fake branded parts so thats on me so i felt pulse and vib from pedal and once i got them shaved the vib from pedal and when braking went away but i still had the vib around 70-80 and i the drive shaft is what you mean i think. Well i have been paying good attention and i can add that when turning left at speed like a long left or a long right i can hear oscillating sound that sounds like a bad bearing on the wheels since once you go straight and less pressure on left or right the sound softens.

I am open to as many suggestions as possible...If this cant be solved then its the end of the line. Ive spent enough time with this.....I just want it fixed but even the dealer wants to just through parts at it at my expense...so please give me some input and ill check them out....it cant hurt ....

hmmm Read about the flex disc ill take a look under this weekend. Thanks

Keep em commin....

So I would like to update my situation thus far.

The flex disc is just fine no issues its not even worn out....looks brand new and no play at least from visual and trying to move it around inspection by mechanic.

my tires were new but goodyear brand and i noticed a lot of bulges/lines on teh side wall so they rebalanced teh wheels and things improved a bit and after a week the vibration came back. looks that the tires are not wearing evenly.

so put new front breaks and today returned the goodyear tires for upgrade to the michelin energy mxv4 tires.

so when driving up to 60 everything is fine. if you floor it to 80 the steering starts to shake as you floor it once you let go allow the car to cruise around 75-80 the whole car vibrates yet again.

like i said front suspension has been inspected twice now and there is no play anywhere. the wheels dont seem to be bent...but i will ask discount tires to do roadforce balance and see how that goes afterwards.

so any suggestions as to what else i should do?

only thing i can do is replace the front end components one more time but thats another 600 dollars...

are you the only owner of the car? i am asking to see if there was ever an accident with it... if there was impact on the rear end, actually anywhere after accidents cars aren't the same!
