Thumbs Up The good/bad vibrations thread

So among the sweet things that us XI owners get to deal with (Axles, One more diff, Open diffs at that, Broken rear springs, non replaceable ball-joints...BLAhh Blahh BLahh) Id have to say the most annoying/frustrating would have to be the sweet vibrations we get, either while driving, or in gear while stopped (ME).

We should all get together and end this SH33T once and for all...

lol I have read countless threads about this and it always seems that no matter what the vibration is, replacing every single piece of the car results in just a 'slight' decrease in vibrations lol. But seriously, there was one where this guy replaced his ****in TC and all of his subframe mounts, and his engine mounts among other things to no avail...

thank god i dont have this vibration yet

oh way.........i do......

I have one that only occurs at a specific rmp (2k to be exact) but I have a new VCG, and ICV as well as besians VANOS rings sitting next to me right now! waiting for soem warm weather (aka spring) to do all of this

I have new rotors, reman GKN axles, unbent wheels and I still get it at like 50/60mph methinks its http://www.ecstuning.com/Search/31537500850/ES51418/

I also had a horrible one at idle (rattling in door) turned out to be bad motor mounts and a loose cable guide from my window regulator (zip tied it) #rickross

It's your motor mounts. Why would your axles cause vibration when you are stationary?

I know what that is like. I recently didn't have a vibration issue, but did a whole bunch of stuff while doing the subframe bushings to get rid of the infamous clunk (diff bushings, TC bushing, engine mounts, etc) and now I actually have a 2 different vibrations now that I didn't have before! I can only feel the one at idle for a few minutes right after a cold start. I was assuming at first that this could be the fact that the new engine mounts are much stiffer than the old ones, but these repairs were done about a month ago and I still get the cold idle vibration.

The second vibration...

...is exactly this!! I noticed it the other night when circling my neighborhood. Seems to start around 1900 and by 2000 it's gone. Have you figured out what this could be yet? It seems to me that it's coming from the front somewhere... my guess:

1.) The bearing pedestal on the passenger side
2.) Front axles / CVs

We can probably rule out control arms, FCABs, and ball joints. I just replaced all those with OEM or PowerFlex parts then had an alignment. Never noticed the vibration until about a week ago.

PS If you've never done the VANOS seals... do it soon! Especially as the problems that worn seals cause are exacerbated by cold weather. Replacing the seals made a HUUUGE difference in low end torque, brought my fuel economy up, and the engine was much smoother overall. It also was the main cause of the idle vibration I had at the time (it just couldn't get the timing right, especially for cold idles), and cleaning the ICV took care of the rest of it.

Did you ever get to fixing that 50 to 60 vibration? I just replaced my sticky left front caliper which was causing massive vibration and brakes are no longer the issue, as with yours.

did you replace the axle seals while you changed the axle?
also did you check the diff fluid after changing the axle?
I change my passenger side axle twice and the diff fluid leaked out so much the diff was making a chattering sound when cold at 35mph.
I filled it up noise went away.

OK guys I'm in the vibration club also. I only hear when I am driving and it is off and on not constant. Car is a 2004 325i sedan steptronic only 55,000 miles. I wanna say it is coming from underneath the car I tried to make a video of the sound but to much wind noise because I only hear it when driving any help would be appreciated it's driving me crazy...
