Spindle install and popping sounds

I have read some referring to awful popping noises coming from their front end after installing spindles. Has the cause been determined yet? Mine are on the way and wanted to see if I needed to do anything during install. Truck has 9,000 miles on it so want to make sure I do it right.

Your stock spindles are within OEM spec, and lift spindles are much longer. The extra length is causing your LCA bushings to pop back and forth as you brake and accelerate. My 07 did the same thing after installing spindles. I haven't seen a fix for it, not sure if there is one. I ended up selling the truck before the bushing wore out.
