I highly recommend going with the diff skids and spacers. The cheap spacer allows you to use the Oem diff cover. And with their skids, the diff cover is never going to get touched. Mine still look brand new and it’s a heavily wheeled 2021.
The problem with these is the taper on the lower C. Most of the rentals, harbor freight, parts stores presses don’t have a cup that matches that taper well. Next time I’ll spend the 6-700 on the Matco pivoting press. No question.
The ball joints are a job. @Shibbyjeep, @Stan H, and many more can attest to that. If metalcloak sold knuckles with ball joints installed, I’d buy them. Put it that way.
You’ll love them. For next time, try putting the three unit bearing bolts in some of the way. Then instead of pushing the bell housing into the boot, you can pull the boot over the bell housing with two hands. It’s worked great for me several times, including just after rebuilding them last summer.
