I have a 05 s40 every time I hit a bump the right front wheel vibrates like crazy and feels like its going to fall off

 

have you inspected your front suspension with the wheel on (does the wheel itself have any play) and off? Any oil leaking from the top of the strut? Is the spring intact (broken springs are common to Gen1 S40s - not sure about Gen2s)? Clunking could be the strut mount, a sway bar end link or bushings or even a motor mount/torque rod. wheel vibrations could be struts, broken suspension component, tire/lug nuts.

 

Yes I installed new lower control arms I check all suspension parts everything is tight lug nuts torqued wheel bearings good

 

Would that motor mount sound or feel like the wheels going to fall off

 

yes a bad motor or transmission mounts can present similar to suspension issues, particularly when power is applied or removed. If you get thumping going over a speed bump or say RR tracks, then I'd suspect the strut mount may have broken. I just replaced one on my 850 - torn right in the center. I could press on the spring and see the strut top nut move... Does the noise or feel change while coasting in neutral through a corner or over a bump?

 

The noise only happens when I hit a good size bump does not make any noise when turning only while I'm hitting a bump and it's more like a bad vibration and feels like the wheel wants to fall off
