Applications

Tech Note 1: GM Steering Knuckles
GM used several different steering knuckles in 1973-1981 Dana 44 and 1977-1991 GM 10 Bolt front axles. The differences are in the length of the spindle studs, how the tie rod mounts and whether or not there is a tapped hole that takes a small bolt used to stabilize the brake shield. The ball joint and spindle holes machined in the knuckles are the same for all years.

Tech Note 2: Tie Rod
With QU30186UBJ steering knuckle, the large end of the tapered tie rod mounting hole in the steering arm is at the top, so your tie rod will be installed above the steering arm and the tie rod nut will be below the steering arm. This Knuckle was designed to be used with a heavy stamped combination caliper support/rotor shield so it does not have a tapped hole to anchor a stamped brake shield used on some other years.

Tech Note 3: Spindle
QU30186UBJ Spindle Stud stick out length is approximately 1-1/16". Spindle Stud part number is QU40054.
