One of the unlucky ones, have a 2016 with the noisy front diff (marbles in the can) and growling driveline noise. Don’t have shim on pinion to move, replaced sprague with billet version a little quieter but still noisy.

Talked to a popo rep and was told in some cases replacing the diff did not resolve any noise issues.

For those that have upgraded from the Model 1333344 to the 1333112 diff, did this resolve marbles in the can noise? Did this resolve the growling driveline noise?
