e46 nasty shake at highway speeds
 
hey guys! my 2004 325xi
-lowered on H&Rs
-Auto
-120,000 km on the clock
-i have 17x8 tsw nurburgrings 35offset squared, wrapped in potenza re760 sports
- 3 months ago i replaced the passenger front cv shaft
-last week i replaced the drive side cv and lower control arm.


i take the same route home everyday, going the same speed all the way home, lately from 90-100 im getting a wicked vibration felt through the gas pedal, the seat and steering wheel. ( i work at a service center) today i got the car up in the air, took the wheels off...inspected, balanced and rotated them. still the problem persist. has anyone had this problem before?

Check your tires for bubbles in the sidewall. You'd be surprised how often that can happen...

tuan_xi 10-27-2010 07:15 PM

^ smooth like the body lines of an e46, any other ideas?

Hub centric ring's for the rim's?

tuan_xi 10-27-2010 07:55 PM

^ maybe? but this is vibration just started latly... ive had the wheels for over a month now, plus i dont think i have room for rings, its almost a flush fit when it comes to the center bore of the wheels to my hubs

When you did the lower control arm, did you change the bushings too? That can cause viberation aswell.

warped rotor on the front?...check if it rubs the pad intermittently

sol_searchin 10-27-2010 08:43 PM

I doubt it's the brake's, IF you drove before with no hub ring's and it was fine then it wouldn't be that. Could be an axle also, Best bet is to jack it up and drive it with the wheels off the ground.

good question, i checked the bushing out when it was out of the car, not a single crack,, everything was intact so i put it back in. but you think that could give me a shake at specific speeds?

im gonna put the car up 2morrow and drive it and see whats up, this vibration is unbearable, its like driving on the warning strips on the highway with bricks for shocks!

sometimes the sticker weights can come off and throw your wheels off balance .. it happened to me.

i also forgot to mention. i replaced my thermostat last week as well, i didnt chip the clutch fan but id thought id rule that out

Generally speaking if it comes and goes at differing speeds then it's a wheel. Swap the front wheels to the back and you'll find out fast.

Possible Lower COntrol Arm bushings have worn? But your car is fairly new so i doubt it.

alignment?

Did you check the inner sidewalls too? I discovered bubbles on the inside before when the rims were taken off. Kinda scary as I had no vibrations or any other indication, yet a blowout could have occurred without warning.
