The rear pads have the metal clip mounted on two of the pads which clip into the piston of the caliper. So would be hard to get that wrong

i have something simular but comes on from 60mph upwards. gets worse when you left off the accelerator. Ive changed rear suspension bushes and prop coupling and prop center bearing. wheels are fine. i have quite alot of lateral play in the driveshafts so im starting to think its that.

[Raahil]

Its a right b***ch so feel for u.
Update: just changed the front control / thrust arms as the garage told me one of them is not central.
Problem is still there
Need to get wheel alignment again now.
Anyone know of a decent garage in west mids who specialise in bmw tracking?

Need to start stripping the rear now!

[Raahil]

Update:

Heard some decent reviews about qwick fits hunter 4 heel wheel alignment and so decided to pop in to get my tracking checked for free.
They also offer a 2 year warranty which allows you to go back up to 8 times in 2 years to get your alignment done again if you have any work carried out free of charge.

Right now i went in and my tracking was slightly out so told the guy to go ahead and track it for me.
He done the rear but then got stuck on the front so told me to come back the weekend as he didnt want to risk snapping the bolt when the parts suppliers were closed.

Drove out from there and VOILA no vibrations!!!
I was a happy Bunny

However a few days on and the vibration is back

Not sure what the hec is going on now. Could something else be the culprit or does it lie just with the wheel alignment??
Any ideas guys

I'm having similar issue, a friend has hinted that a software update on the gearbox might solve?

Did they jack the car up and let the wheels hang down at all? Just a thought but it might have settled or disturbed something.

Is it definitely road speed related? Asking because ive been chasing a "wheel balance" issue which is actually looking more like it was an engine issue all long. In the auto it happens at 70mph but I can make it come and go by holding road speed steady and changing gear to change the revs. Also revving in neutral when stopped causes the vibration around 2800 rpm which can be felt in the doors.

Just some thoughts. Good luck with it.

Did you ever found what the issue is? I have the same problem on my 325d E90 LCI.

I changed the brake discs and braked hard 2 times without locking thr wheels, then I parked the car. Next morning drove to work and from 40 mph car starts to vibrate but it doesnt feel like a wheel is unbalanced, it feels at a higher frequency like driving on rumble strips on the highway.

Took the car to a specialized Bmw garage and the mechanic shows me that one driveshaft is very hard when holding it with the hand and try to pull towards differential. He claims that is for sure giving the vibration so I got both driveshafts replaced.

Got the car back, still doing the same he mentioned its partly because of the winter tires profile on the front that have moved after the heavy braking.

After Christmas I changed the tires and balanced my wheels with the Hunter road force balancer, the issue is still there.

The vibration is still there if I put the car in Neutral, accelerate or brake. I can feel it in the seat and the dashboard + floor. The only rotating part left is the driveshaft so I am going back to the workshop, they have some sensors that are mounted under the car and show where the vibration is coming from.

No mate still haven't sorted mine yet.
When i had the tracking done it was perfect but then a few days later the vibration was back.
So not quite sure if its a loose component or maybe bolts were not tightened up 100%.

In my instance i wouldn't have through it would be driveshaft as if it was i would have expected the vibration to still be there immediately after tracking.

I need to go back and have everything checked over again and have alignment done again. I have access to a works vehicle so mine has been sitting there a while now hence no update

you have checked the calipers?

Hi all,

I've been having similar vibration issues for a little while and found something different that might help someone out.

The BMW shop thought my wheels were missing the 'hub centric ring adapter'. The e90 hub is 72.56mm diameter and some aftermarket wheels (and other BMW wheels) can different, such as 74.1mm diameter. This means there could be about 1.5mm of slack - very hard to notice when installing but at 70mph can cause the wheel to be slightly off-centre by about 0.75mm. This would explain why wheel balancing doesn't pick it up as the wheel is generally removed and would balance fine.

Here is a link to what the shop described was missing (or google e90 hub centric rings)
https://www.ecstuning.com/BMW-E90-33...Centric_Rings/

Here is another thread about vibration that discusses hub-centric-rings
https://www.e90post.com/forums/showthread.php?t=887417

For those in the future, I made a short list of things to check if you've got vibration that's hard to diagnose - in order of ease:
+ check the tyres for anomalies - wear a glove and run your hand over the outside of the tyre
+ wheel balancing and alignment
+ check to ensure you've got the correct hub-centric size of 72.56mm or you have hub centric rings fitted - measure with a vernier caliper, noting that e90 should be 72.56mm.
+ clean and check brake calipers as one may be partially seized.
+ clean the inside of the brake rotors (between the surface plates) gunk may have built up in there.
+ get your lower control arm bushes and thrust bearings checked.
+ If the problem is most noticeable while accelerating, get your flex-disk "Guibos" checked.
+ if the problem goes away when in neutral, get your engine mounts checked.

Anyway, i hope that helps someone out.

Cheers

Edit: updated to reflect what the BMW shop told me, but I've since measured everything and the hub and wheel seem to measure identically.

[vladmury]

I believe you are wrong, the E90 wheel hub size is 72.56 mm. The 74.1 is only for older BMWs like E39.

Thanks, I had the numbers around the wrong way and have corrected the post.

The BMW shop picked up the issue that my car should have spacers, which suggests the wheel shop sold me wheels with a hub centre other than 72.56mm. I bought Beyern Spartan wheels which were supposed to be a direct fit.... Though i see they come in two sizes - 72.60mm and 74mm. https://www.beyernwheels.com/BMW_whe...hp#wheel-specs.

I'm going to take a wheel off tomorrow and measure everything. While I do trust the BMW shop they annoyed me that they wouldn't help resolve it as 'they only install genuine BMW parts'.

I've arranged to take the car back to the wheel shop that sold me the wheels on Monday, so will at least go in fully informed. Perhaps they accidentally ordered the wrong bore size.

I'm pretty sure this is my issue - I've only had the vibe since putting on new wheels - and it feels like this is what's happening. I'll know more tomorrow once i measure everything. I'm in Auckland NZ, so my range of stores and options is a bit limited compared to other places.

Cheers

OK, so I measured everything and both the hub centric ring and inside of the wheel measure the same: 72.6mm.

So it seems there is no need for spacers, and the wheel shop did the right thing and the BMW shop may have led me astray. Quite annoying. I was certain that was the issue, but it is not.

The tyre shop did re-mount the two rear tyres back on the rim before i took it to the BMW shop, and I've only just had a chance today to get up to highway speed and the vibration is much less noticeable.... so i'm going to just keep an eye on it.

Cheers

Sorry guys i have been inactive on the forum lately due to work commitments.

Yes my problem was solved in the end which was bottled down to wheel alignment. It turned out the chap who was doing my alignment was putting the wrong vehicle spec. hence was setting my tracking wrong!!

To those who are having the same problem i would go to a couple of different garages and get your wheel alignment checked out.

Hope that helps

I have the vibration at 85mph +.
New tires rims drive shaft carrier bearing rubbers front and rear, full alignment. Ambient Air Temperature does affect it the colder it is the longer it takes the vibration to appear. I have a friend that is a engineer the a race shop that ran this model. Even he is stumped.

Thank you!
