72 caprice

[mattbarr]

i have a caprice which has no rubber in the motor mounts and it shakez alot when you drive it. its got worse and dont want to move when i put it in gear i can hear tha transmission grindin...could this be just because my motor slid all the way up

The car does not move under power?

I find it hard to believe that broken motor mounts would allow the engine to slide forward ... perhaps not straight up and down, but it wouldn't move forward. I used to have a 1972 Impala so I am familiar with the car - the motor mounts on these are a solid rubber block with flanges on each side.

Sounds to me like you have a bit more going on here than just broken motor mounts.

driving with the motor mounts totally broken will damage the frame mounting brackets and the holes for the engine mounts wil get elongated..


if you replace motor mounts you may have to use a larger diameter bolt or get the frame brackets fixed by welding a plate or replacing...


i'm sure your transmission mount is gone also....

i had my motor switched and the guy who did it only hooked one side of the motor mounts up. and the upper and lower mounts didnt even match up because of the swap i didnt kno all thiz untill i took it to te shop for the shakin. i had a new transmission mount put in because the guy didnt hook it up either that mad the motor shake more and i started havin more trouble with it......it wouldnt move before n i put a bolt back thru the mount and it started movin again but it vibrated back out ... i can see that the motor has moved up also

do as i stated earlier......replace all mounts and brakets/bolts if necessary....


the person that installed your motor is a hacker....find a good repair shop....
