I have a 91 chevy c2500 Silverado 2wd that I just recently did a brake job for replaced with new 6 lug rotor/hubs and new pads and noticed how close the the lower control arm was to the rotor while I had it jacked up and when the truck is on the ground it’s completely butted up against the rotor... keep in mind this was my grandfathers old pickup That was passed down to me that I’m trying to fix up so it’s never been serviced or maintained properly hell the thing has never had an alignment since new... and all the suspension is still factory... only has 132k miles I’m wondering if it’s suspension related like lower ball joints or the rotors I got are the wrong size has anyone ever had this problem before ? Here’s a picture of when I had it jacked up how close it is to the rotor

I would check to make sure your rotors are the right size. Take yours in and compare them to another set.

If this checks out, start examining the ball joints and pivot points for slop. I bet you will find one collapsed or very, very loose.

Thats my next step i am wondering if the 3/4 ton truck with 6 lugs had two types of rotors light duty and heavy duty like the 5 lug trucks had?

did you check bearing for looseness, im thinking the spindles are different size and the rotor is sitting farther back on spindle , you might have to go back to 5 lug rotors
