2003 330i terrifying vibrations at 65.

[Stiggy]

Throwing another dollar on the pile. I'm betting it's tires out of balance / out of round.

Huh. Didn't even think of a busted belt in the tire. They are getting pretty cupped. Car needs an alignment hardcore but I never get the car to work since the gf drives it 100 miles a day.

Ill try to throw it on the lift tomorrow and see if I can see anything obvious going on under it. This thing has been driving me nuts lately.

[vert_this]

yeah I go with a busted belt in a tire too..

Your car is having cocaine withdrawals

I bet you 5 bucks it's a seperated tire.

[Swanny]

if it's starting to rip apart, the resonance could easily make it shudder at certain speeds.

Yeah MAJOR fail in the rear subframe mounting points. But kinda sounds like a wheel balance/ tire issue. Just had a set of tires delaminate on me and that was a blast to find out.

Swap your wheels and see whats up?

[trippmann]

check your tie rods, i had a shudder around that speed and when i replaced mine it went away completely.

As in death wobble in the wheel?

[slammin.e28]

I thought that was just a huge clunk on hard takeoffs? No clunking going on. Just a death shudder at 65. Goes away at 70.

[Kershaw]

rear subframe?

dont e46s have a massive failure point in the trunk/rear subframe mounting location? for it to be fixed, plates have to be welded in.

don't die. park it until you figure it.

[slammin.e28]

Seriously. Feels like the car is going to fucking fly apart. It's got 150k highway miles. 5sp car. Sometimes it does it taking off into a turn in 2nd gear but not always.

I'm at a loss. Guibo? Ball joints? I just did the lollipops. Car is basically fine until you hit 65 then it's death.
