Here's one for you: Was out enjoying the fruits of my labor, in the GMC, today. Hotrodded it all over town enjoying stopping at every red light to feel the all disc brakes and to hear the engine idle. Parked on a hill at my daughter's to check on my grandkids. Put it in reverse to back up a pretty steep incline and heard what sounded like a stick dragging real hard on the blacktop. I had my foot in it more than normal backing up the hill. Got out of the gas and it stopped. Tried it again and heard it once more. Now, I have a glass engine cover and I keep it clean so I can see what is happening. Well, When in reverse, with my foot hard on throttle, the rear of the engine, on passenger side is jumping up. I am sure it is causing something to be misalligned and making the noise. When I get out of the throttle the engine goes back to normal resting place. Stop on flat and hold foot on brake, with lots of throttle in reverse, I can make the engine come up on rear pass side. Forward all is good.
So, the right rear mount is busted or loose. I suspect it has seperated. What do you think? This is hard to tell, from my experience, by just looking at one. We had the engine and trans out a couple of years back, never noticed anything. May have just snapped or it may have been this way for 50,000 miles, as I have never gunned it in reverse to back up a steep hill before.
Bottom line, is it hard for one guy to replace?
