I have no idea why, the replacements seem okay, work fine for a bit, but they just don't hold up. I was in a pinch and bought a Westar upper mount for my Honda Odyssey, and it needs replaced in the worst way less than a year later. I had a similar experience with a Saturn I owned, that was an Anchor replacement, after a month replaced it with an OEM mount, and it lasted the remaining life of the car. You really do get what you pay for with these things.
On a side note, I once used hockey pucks with a hole drilled in the middle, as a replacement for the rubber front mount on a 2000 Bonneville (3.8L supercharged engine) at the suggestion of a bunch of forum members, and that was the longest lasting, best performing mount I've ever had. Go figure.
I have used 3m Window Weld to fix the upper mount on my Mazda Protege5.
I took the mount off, covered one side with cardboard to prevent the urethane from leaking out and filled it from the other side. I let it set over a 3 day weekend while I was out of town.
More vibration conveyed to the passenger compartment. But for $20 vs over $100 for a new mount, I'm ok with that.
