Front end clicking
 
2001 325xi Touring.

I just had my local mechanic put in a new diff seal on the passenger side, and he put new diff fluid in the car.

In the morning, when the car is cold, I take off and hear this wheel speed clicking/ticking. It is not a consistent speed (like straight eighth notes). The velocity of the noise will increase and decrease with wheel speed. I have slowed down and reved the engine to see if that would change the noise, which it did not. Pressing on the brakes hard while its making the noise will slow the noise down.

After the car has been driven a couple of miles, and everything warms up, the noise subsides and the car runs as it should.

Here is a video (really just the audio) of the noise. There are not codes, dif fluid was just replaced by a respectable shop. It seems like the noise is coming more from the driver side. The passenger axle has been replaced. I have a driver side axle waiting to go into the car, I just haven't put it in yet.

Any thoughts?

I had a hard time hearing it from the vid but what you are describing to me at least sounds like its time to put the axle in.

could be CV (which means its time for a new axle)... could be wheel bearing...

Put the axle in and see if that is it.

This morning, it was 9F outside....and the clicking wasn't present.

I also notice that it isn't consistent with wheel speed...and the volume changes. I can be going up through the RPMs, and have a moderately loud click....coast for a bit and the tick goes away, then when I get through a certain speed range, the tick comes back and it is super loud.

Doesn't make any sense.

Classic symptoms of a bad CV joint, it makes perfect sense. Noise changes with load on the joint. Basically if you have the axle ready to go, why don't you put it in to alleviate that as an issue.

Who's your local mechanic? I have been using a shop in Hudson, WI that has been doing a pretty good job with stuff and has been pretty reasonably prices. My two biggest complaints is how long they take to fix stuff and they are SO busy I can never get in in time. If there was another one in Minneapolis that I could use.....

Right on.

This needs to be replaced, the motor mounts need to be replaced along with the rear diff mounts. . blarg.
