Motor Mounts
« on: March 10, 2026, 12:02:18 am »
I have a broken motor mount I need to replace, on the passenger side. The bolt that holds the two pieces of the motor mount assembly is absent. I'm just assuming the rubber part of the mount has been damaged by a broken bolt wobbling around in it for who knows how long.

Last time I replaced motor mounts, the engine was out of the vehicle. Easy peasy. Not so this time. Now I have all the things in my way.

So I'm looking for advice. Things I should do. Things I absolutely should NOT do.

Any input is appreciated.

75 Chevy 2wd; 350/TH400; lowered 3/4; headers; no a/c; not sure what else you might need to know.

For the work involved (not that much) I think I would replace the bolt to see if it's really broken.

I wouldn't even put the nut on at first.

If the motor pitches with the bolt in, then your assumption is correct.

If not, tighten the nut and bolt and go for a ride!
