Clunk During Turns Gotten Worse
 

When I purchased my 08 X5 4.8i Sport i noticed when i made sharp turns at high speed (causing the car to lean heavily to one side). I would feel and hear loud clunk coming from the front around where the suspension is. As i have driven the car the sound/clunk now happens pretty much on all turns. I also have the following code (maybe unrelated): P3027. Can anyone help me understand what this could be?

I think you need to get that up on a hoist with a suspension specialist.

If it's leaning heavily to one side on high speed turns I would suggest it might be a broken swaybar link.

Car doesnt lean or handle poorly, it just makes a popping sound when the car is turning. When I first noticed it, they put it on a lift and couldnt find anything wrong, however I noticed it got worse after i replaced my thrust bushings, and I think my axle may have a leak in it as well, again both items could be unrelated.

The code is an O2 sensor code.

You need to have your suspension checked. They should be able to determine what is causing the clunk and by doing nothing is making your vehicle unsafe as time goes on.

What i meant was that when I would be driving 'fast' and turning like onto an on ramp and the car dipped to one side a lot (naturally due to speed and angle of turn) i would hear it, but now i hear it even if the car is not leaning much while turning slowly. I also now hear it if the car goes over a bump while turning.

Ahh i see. I'm still calling sway bar bushes or end links.

When you replaced your thrust rods/bushings did you do the job yourself...just curious? Also + 1 on swaybar end links, cheap to replace yourself usually go out depending on mileage/age. Could also be your steering rack...the majority of the time your car will not duplicate a noise on a rack b/c the susp. isn't under load. Does it "pop" while turning at a stand still?
