Damaged Wheel

i ain't no betting man...well the mega millions is nearly up to half a billion dollars, so i bought 2 tickets, but i'b be doing what i told you earlier, jack up the entire rear end, and hand spin (maybe with a helper) the wheels and listen for a grinding noise out of the rear banjo's.

but if you hear "dueling banjo's" you're hearing the wrong ones.....

 

you know what..??

the drive line angle must be off. those u-joints are most likely at an angle not proper to the line. you may have to get the truck to a specialist in drive lines, and have him use an angle gauge to determine the angle.

you may have to put on the PROPER size tires that the factory had on originally. not anything larger, OR smaller..

 

you have to find out why, that center bearing was even installed like that (the old one). is that cross member removable? or riveted in place?

if removable, i'd wonder if it was replaced backwards

 

Have you actually got the ride height spec from the manufacturer? And checked it against your truck with a tape measure? If not why the hell not?

 

Tire sizes will not change the angle. Assuming all 10 tires are the same size.

 

it doesn't take much to have the (newer) rear axle installed slightly off, where the naked eye does not pick up on the difference. however, you said you had an alignment, the alignment rack depending on if done on a rack or portable pads, should have picked up on a misaligned installed axle.

 

ok good. back in my mechanic days, we had no "computerized or real alignment racks, we had pads and a magnetic camber/caster gauge you'd stick onto the front hub, and only could do front wheels. and you had to hope, that you found the level spot on the garage floor as well...!!!!!!
