Going to try the power steering pump and the the DS hub assembly this weekend. If that doesn’t do it, I guess new tires will be the next guess. Had the rims inspected and nothing was found wrong.

What are your thoughts on the rear? Is it possible that one of the rear bearings are bad and it’s vibrating through? Wouldn’t make sense with it worsening when turning wheel slightly to left I guess.

My mechanic thinks it may be the rear breaking down. Only thinking this because when it was off the ground in neutral it took 2 hands to spin the wheel. Same on both sides. Is this normal for the 1500’s or should they spin with ease. He has a GMC and his spin with just a few fingers pushing it. Any thought that the rear itself may be causing it? I still think it’s front end related since it whines more so when the wheel is an inch or so to the left.

 

Think I would have a look at the rear brakes. Disc brakes, aren't they? If the brakes are holding to tight, that could give you all sorts of interesting issues.

 

They would have be holding while disengaged to be a factor in the problem he described... in which case, they'd be red hot.

 

They would get hot, that's for sure. But, red hot? Haven't seen that one yet.

 

Checking your tires sounds like a good step.
Check condition of your inner wheel from under the truck. Look for any mud build up, thrown balance weight, or wear point indicating that the tire is rubbing steering/suspension components.
Check torque on lug nuts.
Get wheel off of the ground and check for play at the 12/6 position (ball joints) and 3/9 position (tie rods).
I'm having a little trouble following this thread at this point. If I read correctly, your initial concern has been addressed and we are moving to new problems. Consider starting a new thread. There may be members who can help with new problems.
