Quick Suspension Question

Hi All,

I have an 07 328i with 111k miles. I just had the struts and shocks replaced with OEM as well as the front arms... The ride is much better, but it still seems to have more vibration than I remember around 70-80 mph. Is there something else that should be checked or is it just because my car is getting old? I also just put new tires on the front and the back ones are still good.

Thanks for the help,
Matt

you could have a front wheel bearing going, I had a vibration that I could feel in the steering wheel on my 4runner at around 65 MPH, jacked up the front took both wheels off, when I would spin the rotors I could tell one side felt a different, and not as smooth, pulled the wheel bearing assembly and replace it, when I took the old one apart the race on one bearing had a rough spot about the size of a pea, replacing it solved the problem

Poor wheel balance usually has a harmonic @ 75 mph.

You had a lot replaced; did you do an alignment, too? I would do one if replacing the control arm bushings (which I believe you did.)

Yeah, thanks. It was the control arm bushings that I had replaced... I was thinking it is probably some issue with the wheel(s). The tires were balanced and the alignment was taken care of as well.

My rims are severly curbed so I was thinking there could be wheel damage? I trust the guys at my local shop and they said to bring it back in a couple of weeks to have it aligned again as the new suspension needs to break in. I will follow up with them. Thanks for your guys' help.

Could easily have a bent rim. Usually the person doing the balancing will notice it.

Check for bent rim as Floyd mentioned (I know I have two that are slightly bent...threw them in the back). Also check for a humming noise when cruising on smooth asphalt between 25-40 or so mph, you'll notice it much more if slowing down from say 40'ish on smooth pavement. A sign the wheel bearings are going, about $50 or so a piece on oembimmerparts.com. I'd get a balance done as well AND an alignment since you did replace those control arms, but I'd wait until you do the wheel bearings as well (if needed, most likely a firm yes) as you'll need an alignment more likely than not after swapping those.

Have them check if your tire is out-of-round. Even brand new tires have defects sometimes.

***Update***

It turns out my local shop really did not know what they were doing or they had lazy staff. I ended up taking my car to the dealer. I had to replace 3 of my wheels/rims (they were bent) and I had to get a new camber bolt for the passenger side rear wheel. After replacing the wheels and adjusting the rear alignment (after the new bolt), it drives great.

Thanks for the help,
Matt
