I put the axles in because I destroyed them changing the wheel bearings. They were/are in great shape bearing wise. I just mangled the nut ends.

As for hunting for the vibration I haven't at all. I read several places it was kind of normal and bmw even had a tis about changing the idle speed to solve it for people so I just figured it was something I had to live with.

If its not normal I may hunt for the cause. It has over 200k miles on it so motor mounts could be shot and a number of other areas. Im waiting for next year to do a suspension refresh with all new struts, bushings etc.

How bad of a vibration is it? I can feel it ever so slightly when I’m at a stop light. In neutral , it’s perfectly smooth. I don’t think it’s alarming just a light buzz in my seat.

That sounds like what mine does. Nothing in neutral and a middle vibration in drive with the ac on with the ac off and the rpms drop lower it vibrates pretty bad annoying wise. But since I run the ac all the time its not to bad. Heck the motor mounts could be toast at 200k miles.

Mine is at 174k now. Bought it recently with all records and dealer records. Lady had it for 10 years, I felt it on the test drive but it’s my first e53 and thought nothing of it. I’ll have to check the cv axles then.

I changed both front output shaft's last week. Old one's had lot of play. Now with new shaft's I can feel quite a vibration while foot on the brake and on d/r. It seem to resonate more when ac is on. But as soon as you let go of the brake it goes away and while driving no issues. Probable next best bet will be engine mount's... Old shaft's probably ate all vibration because they had so much play in them?

When the car is cold, doesn't seem to have that problem.

Your motor mounts may be shot.

New motor mounts are in. No change on the vibration...

Have you tried raising your idle speed? If you have the Foxwell scanner its simple.

[zener]

Not yet, but I tried it with d on and with gas pedal and it won't go away until 900'ish rpm...

Did you also change the transmission mount? Guibos? Only other thing that comes to mind is the harmonic balancer starting to die but that is extremely rare and only some engine models had a problem if I remember correctly.
