ok this is very weird. i have a 99 quadcap dually 4x4. when i turn my turck to the right and to the right only there is a very weird grinding noise. its when steering wheel is turned almost all the way to the right. there is a sweet spot were i can get it to grind constantly. i just replaced the center link that was going bad adn it did tighten things up but noise is still there. i am hoping that it isnt anything to do with the bearing hub assembly cause those aren't cheap. any help would be great. thanks in advance.

 

first order to look hub, axle joint. and then really should safely raise it on jacks doesn't need to be to high start it and turn the wheel. have someone hold it and look . see if you see any contact spots. but this may need to have the weight of the truck and motor to make the squeal. real easy to check the hub. I dont think a ball joint would make a grind this bad.

 

axle u joint

 

my truck currently does this to, but when i turn to the left.

are you sure it would be an axle ujoint? my buddys truck did this, turning both ways and it was a 2wd.

 

either that or a wheel bearing? what did your buddy do to resolve this on his 2wd?

 

I'll throw this out there just in case: It's not something simple like a corner of a mudflap or the splash shield that catches the edge of the tire tread when the wheel is turned a certain amount? Sometimes those will make a pretty horrific sound.

 

Just to eliminate basics.... not running 315 tires are you??
I mention it because mine only rubs to the right also.

Something else to check. My truck was doing that and it turned out to be one of the brake caliper bolts broke off (one of the two sliding bolts).

 

he just sold the truck he got tired of the whole thing giving him problems.

 

Might be the clutches in the rearend. Mine is notorious for this, get it fixed with just the right oil and anitfriction additive but go through it everytime I change the fluids. Mine is always worse one direction.
