Hey guy I have 2005 dodge diesel 4x4. I have new ball joints wheel barrings and shocks. I have a bad thump under the drivers side and I can feel it in my floor board. But it only starts Making noise when it gets cold. When it's nice out doesn't make a sound. Anybody have any ideas

 

I have the same problem in my 1997 F-250 on the passenger side. It was so bad at 50 MPH I pulled over thinking I had a flat. It also makes a squeeling noise when I turn the wheel to the left shifting weight on the right front. I am thinking I need new wheel barrings or ball joints. I am not sure if mine only does it when its cold out since it just started and it hasn't warmed up enough to say its weather related.

 

Did you replace any bushings? Or have you inspected it lately?
