Front engine mount

Keith_Milford · 2 Weeks Ago

The rubber in my front dogbone mount is shot. Got one at PAP today, on impulse, and it's about a half inch too long., but has excellent rubber. Is there any way to swap out the rubber? Are they molded in or pressed in? Any suggestions would be appreciated.

Always take the old unit with you so you can match up the part. Auto parts will give you the wrong one to lock in the sale. Did you ever guess why there always laughing , the joke is on you.

No, I wasn't taken advantage of. I went to the junkyard for something else, and just saw this one that looked about right. Nobody's fault but mine. Figured I'd take a chance and grab it. Anyway, how do I swap out the rubber?

I think it is pressed in at the factory. You might damage it if you try press in a used one.

Mine looked too long as well.
What I did was bolt it in on the radiator side, had someone I trust put it in drive with the brakes on, accelerate slightly. The engine will shift, slide the bolt in, put it back in nuetral, tighten the nut, and you are done...

If it don't fit, get a bigger hammer. Both the Fiero and the white car measure 4 1/4 inches across the bolt centers.

I would think that a longer dogbone would stress the lower motor mounts. Not cheap.

They are $12 new.

You would ruin it by trying to replace the rubber mount. Take the one you got from the salvage yard down to the parts store and ask them to pull a new one for you. Match it up. If it is wrong, buy a new one as D-a-n-i-e-l has said. For less then $15.00 it's not worth screwing around, trying to swap out a mount.
The one I got from the parts house seemed to long as well, as the bolt dead ended on the rubber. As I stated earlier, I was confident that I was given the right one, so rather then fight with it, I did the trick I stated above.

Well, I'm sure this one is longer than the one that's on now. When I sit them side by side, it's a little over a quarter inch longer. However, I believe it is about 4 1/4" long (between bolts), so I'm wondering if the one that's on it was a "too short" replacement; it's only 4" between bolt centers. This might explain the extra stress on the rubber that caused it to fail. Anyway, if I were to look for one of these online, what would be the "official" name for it?
