First off, what'* wrong with the pictures below?
Well, when I bought the car a few weeks ago, I didn't realize that wasn't the stock front motor mount. I inspected the car as best I could before I bought it, but not being familiar with the Bonneville'* before buying I just didn't know what to look for besides the usual stuff. I could tell something was amiss because this mount has had black polyurathane sqirted into it for additional support. I though it must have been getting weak or something. I realized after I bought the car that the EBCM was not permanantly mounted and was sitting an inch or so from the mounting holes. That'* when I put 2 & 2 together and realized that mount wasn't stock. At least not on the bonneville. I'm sure it was pulled off another 3.8 somewhere since it matches the holes. I confirmed that it wasn't stock when I got my service manaul.
So today I'm doing further inspections on the car cause I know there are some bugs that need to be straightened out and I want to know what else needs to be added to the list. I pulled the drivers side tire and found that the back motor mount (right trans mount according to the service manual) is not even attached.
There is one bolt on the lower of the three holes that has busted out the side of the mounting hole and stripped out all at the same time. The bolt was still there but barely. The other two bolts are completely missing.
I figured they were stripped out too but can't really tell, so off to the store I go the get replacement bolts. I get back and guess what, the top outside hole is stripped out and the top inside hole still has the bolt shaft in it (head busted off). I'm not a happy camper at this point.
So, how important is the rear motor mount on this car? I'm thinking the front mount was ugraded at some point to accomidate for the missing rear mount. The car runs smooth with minimal vibration (which sound normal according to many of the post I've read). The only thing that bothers me is what happens if the front mount gives way? And I'm sure there is extra movement in the motor too without the rear mount. I am open to so any suggestions at this point. Replacing the tranny is not an option. I see the tranny was replaced before from the GM sticker on the side of the tanny, which makes me wonder if someone forgot to tighten the bolts good?
I'm a bit pissed, but beyond this, I love the car. I'll keep driving it no matter what for now!
