In this episode of Deconstruction, Kaleb and Brandon tackle a full rear differential swap on a Mack semi truck. This wasn’t cosmetic—it was mechanical, and it needed serious attention. One minute you're rolling—next minute the tires are free-spinning, you hear a snap, and you’ve got nothing. When the rear differential gives out, the whole truck's deadweight.
Kaleb and Brandon dove straight into teardown, pulling the rear and swapping in a reman to bring this Mack back to life.
From teardown to reassembly, we take you inside the full process: Identifying a failed differential Removing the damaged rear end Prepping and installing a reman Checking alignment and tolerances
No shortcuts. Just skilled work from techs who live this every day. This is the kind of work that keeps fleets running—no spotlight, just solid work from the shop floor.
