X5 pulls hard to left when accelerating
 

This may sound strange, but when I floor it, my car (2006 4.8is) pulls hard to the left. Under normal driving (note, my normal driving includes flooring it, but for the sake of explaining my issue, I'll assume it doesn't for the moment), it still pulls to the left a little bit, but nothing particularly noticeable. I am not sure if it is a bad alignment or my air suspension or suspension issue.

As for my air suspension, I am having issues with it. The left front collapses at night once to twice a week. It is also regularly lower than the right side by an inch or so (measured from top of rim to fender).

Anyone know what might be going on here?

Thanks,

As far as one side lower than the other, you probably have a leak in the air spring/bag. It might be a bad sensor but it sounds more like a leak.

On your handling issues, not sure but I would take it to your indy or dealer to have it checked out.

Good luck!

Your rear subframe bushes are shot causing the subframe to go out of alignment and steer from the rear. You need some stronger polyurethane bushes in there to sort this out.
