1996 TL 2.5 front motor mounts broke were replaced by new acura mounts, then broke again in less than 5k miles. Is there an underlying problem? Are after market mounts available?

 

people had them busted before, but there isn't a TSB or anything like that.. as far as i know.

I have replaced mine like 10k ago. and they are still fine.. I think.. i am still dealing with vibrations..

how do you know they broke?
who installed them?
