Same experience here. You replace a 15 - 20-year-old original part that finally gave up the ghost with a brand new knockoff rubber parts. And then a year later... it needs to be replaced again.
Haven't had that happen with motor/trans mounts yet (I replaced my trans mount with genuine), but I've seen first hand how other rubber parts fall apart quickly:
- front control arm bushings - quickly showed cracking, then tearing, replaced a year later, 4 or 5 years on OEM replacements since then and they're still fine
- Intake rubber accordion hoses - sure, the 25-year-old original was cracked, but the replacement turned flaky/mushy (a combination of dried out crumbly stuff and sticky black goo) within a year. Replaced with junkyard parts that were a couple of decades older but better. That was on a late 80's Celica.
