New Owner - Vibration & “Wandering”

I’ve owned my E46 (01 325i) for just over a month and since I bought it the steering felt loose and on the freeway it felt like it would kind of float a bit and i would really have to make a lot of corrections.

Day 2 of ownership I put on 4 brand new tires and had an alignment. It helped a bunch

Last weekend I replaced the steering guibo and while that tightened it up a bit, the wheel sort of shakes/vibrates left to right at freeway speeds and it also feels like I have to fight the steering wheel when driving.

The other thing it does is really weird since replacing the guibo. If I hit a significant bump at speed the car will want to shoot off one direction as if it has a mind of its own.

I’ve had a mechanic do an inspection on the car and all suspension components seem to be fine including the lower control arm bushings. any ideas what could be causing this? The tires are new, it aligned just fine, the wheels balanced just fine.

Replaced the front lower control arm bushings and had the alignment redone. Still has vibration in the steering wheel at highway speeds but not as bad.

Any ideas for what else it could be?

Hey there,

If you look around there's a lot that can cause vibration at speed. Thats what everyone here will say is use the search. But first, if it is really the steering wheel shaking (make sure it's not the driveline vibration at a certain rpm), you can narrow it down pretty quick.

Maybe go get the tires rebalanced because these cars are really sensitive to tire balance. You might want to inspect for any bends In the wheels as well. I had a small bend in a style 68 that caused horrible vibration only at some speeds.

I would definitely do the tie rods inner and outer. That helped my "wander" and it helps vibration too if your inners are really shot.

Does it vibrate under braking or pull to one side bad? Your rotors can get warped and cause a small vibration even when not braking, but usually it's pretty consistent and not at one speed.

Also you may have jacked your alignment when you did the guibo bushing. There is a little bit of variance you can introduce when you unbolt the rack. That might explain why the car wants bump steer now.

Lastly how many miles does the car have?

Thank you for the detailed reply. It is appreciated. I should have prefaced my posts with “yes, I’ve searched and have been searching.” As a 20 year car forum veteran I should have known to state that.

The reason I posted yet another “what’s this vibration” thread is simply because you can’t search by “here is what I’ve replaced. Now narrow it down.”

I’m starting to wonder if it is the rotors now. It does pull to one side but doesn’t vibrate while braking too much that I can think of. I’ll have to pay closer attention.

I did the guibo and the CABs prior to getting it aligned. I suppose I can take it back for rebalancing but like I said, I got brand new tires the day after I purchased the car (6 weeks ago) and they were balanced then. Bent wheel/flat spot did come to mind so I’ll need to see if I can get that looked at. I’d really hate to have to spend money on wheels at this point, despite being a bit of a wheel whore on my other car.

The car is about to roll over 160k.

Thanks again for the advice.

Tell me, did you check the transmission? Did you check the wheels and suspension?
How does your car behave at low speeds?

I need to double check the wheels but I just got new tires on them and there were no issues balancing but I should still re-check for bends.

Check the transmission how? Yes, checked the suspension for play checked bushings and they seem fine.

Question: could bad motor mounts cause this? At low speeds it seems ok but I do think the motor mounts are likely pancaked...

Motor and trans mounts have now been replaced. Rotated tires front to back and the steering wheel still shakes back and forth/vibrates at highway speeds. I’m out of ideas.
