4 Using a hand file or grinder, remove the original roller’s rivet head and then drive the roller body out of the regulator with a hammer and punch. On stock regulators, you’ll need to drill out the roller hole to 1/4-inch, but on the Electric-Life, it’s already the proper size. Slip the regulator end over the new roller and install the retaining nut with a dab of thread locker. Repeat for the remaining rollers. We also secured the rollers from the window frames with thread locker for good measure as well.
