As an engineer, I've designed, installed, and changed out pneumatic pressure regulators, hydraulic pressure regulators, and variable digital regulators, as well as check valves, flow dividers, flow regulators, gate valves, needle valves, ball valves, sweated fittings, threaded fittings, and welded fittings. I had never before changed out a residential home's main pressure regulator.
I needed a 70XL pressure regulator, which Home Depot had for $70. It fit beautifully into place as a retro fit for the existing failing regulator. All I needed was a pair of ginormous (larger than 1.5 inches) channel locks, and 20 minutes. You can do it too. Read the label on the failing regulator, and get yourself a replacement in-kind. Don't re-use the old seals, and buy an unmolested package that has not been opened-and-returned, so it has all the required replacement hardware.
