The impact sockets almost always get great reviews from the afore-mentioned dead horse threads.
For a box in a professional, daily use environment, my advice would be pass on Harbor Freight tool boxes and keep looking. (At home is a different story). You're going to be putting literally miles on the wheels pushing it around, depending on the size of your shop. Every time you hit even a small crack in the concrete you're going to be racking the welds, the sliders, and flexing the cabinet, especially when loaded down with big/heavy tools for diesel repair. The big boxes have suspension wheels for this reason. Most old concrete floors aren't level, let alone even, so you'll have to be careful where you park your box, so the drawers don't all open at once (depending on model). Professional boxes have deeper drawers, (less chance of tipping), etc, etc...
Will HF it do it? Most likely. However, a professional box will offer years of service, vs. the HF quick, temporary fix. There's a good reason sane people pay $8,000+ for a tool box: its worth it in the long haul.
I bought the 5 drawer cart at Christmas last year, and its already started wearing. The bottom tray the wheels bolt to has dented from me trying to push the box over a small extension cord. It won't roll over anything more than about 6mm/1/4 in. diameter. The paint has softened up from wiping it down with hand cleaner wipes, and one of the gas lid struts has died. I still would buy it again, but be prepared to make repairs as needed.
As always, YMMV. Good luck!
