Hi
I have a 2003 f250 superduty v-10 -- 4x4 --
when turning with 4wheel drive disengaged I have consistent thumping sound coming from front end -- more so when turning to left but still prevalent on right turns -- I put new hubs in due to the grinding noise when driving slow to mid speeds -- like axles not totally disengaging and grinding on teeth. but this is a secondary noise -- replaced left front axle with dorman unit -- tried to replace u joints on oe axle but rusted so badly couldn't get c clips to separate from ujoints --

this one is kicking my butt and making me look like a novice --

don't think it is ball joints or anything suspension related but I could be wrong -- sounds like thump thump thump as turning in slightly tight circle or going around corner in parking lot any help would be greatly appreciated.

Jeff

 

Hubs locked or unlocked?

Try both ways.
