Bad motor mount=Vibration

Picked up a vibration in my 87.While tinkering on the engine I took 5 steps,turned back and low and behold the motor was leaning to the passenger side.Upon further inspection I found that I have a broken motor mount.Does anyone make "better" mounts like say,Energy Suspension for our trucks? edit I did a search after I posted and found poly mounts sorry

Trans mount can cause vibration too.

Also, installing poly mounts may cause more vibration also, as they do not insulate/dampen as well as rubber. They are performance items.

It's easy, it goes at the end of the trans, 3 or 5 bolts, can't remember. Take the weight off the trans w/ a jack (use a piece of board under the pan if it's an auto), take the big through bolt out, jack it up as far as you can, remove the bolts holding it to the trans. Replace in reverse order.

I have a 1980 d150 with a slant 6. One of the motor mounts looks bad. Anyone out there ever replaced these and willing to offer some advice?

Thanks in advance.

Thanks for the reply.I was wondering how hard the actual job was. I called a local shop, and they quoted about 200 bucks. I assumed I'd have lift the engine , so I'd have to build an A-frame lift of some sort(out of wood in my case) Just trying to deciide if its worth doing it myself or not.

You don't need a lift, just jack up the engine a little and unbolt the engine mounts. It is a very simple job. And $200 is a rip off specially since the mount only cost $4.50 each at NAPA.
