Good. The motor itself isn't the issue..
Like many drivers of 1st/2nd-generation Ford Explorers, my rear wiper motor failed. I finally got around to replacing it. Got this unit, and it was simple enough to install. So far, so good.
Other people have had this motor fail on them too. In fact I have heard stories of people replacing the rear wiper motor more than 10 times while they had the vehicle. This is NOT necessarily a fault in the motor itself, but rather the fact that the wiper, when not in use, rests on the tailgate below the window. When it is turned on, the motor first has to raise it up to the window glass. Unfortunately, the wiper sometimes gets caught in the gap just below the glass since the spring in the arm is forcing it forward against the vehicle. This is hard on the motor, and if it happens enough times it can strip the internal gears so that the motor must be replaced.

Rebuilt 40-2030 rear wiper motors don't last
Since the original rear wiper motor failed on my 2000 Expedition I have replaced it with Cordone rebuilds in 11/2013, 1/2014 and 3/2017. It's now 7/2017 and I'm about to replace it again. It's good that there's a lifetime warranty but replacing it is getting old. I disagree that catching on the window lip is killing it, at least in my case. I spend a lot of time aligning and shimming that motor so it's perfectly placed and does not catch. I did get 3 years out of one of them but two have failed in just a few months. And the directions that come with the motor that say to align it so it sits 1 to 2 inches under the wiper arm catch are nonsense. It will never work properly that way. Having replaced three of these already and having attempted that alignment, I know. The only way I've found to align it so starts and stop from the wiper arm rest is to align it from there, not 1 or 2 inches below it. It does not catch on the glass when I do that.
