Red58, No offense taken. I just did not want you to think I was a 20 something kid that liked trucks and did not know how to drive.

It jumps and I have to retry. Sounds like it happens to you once in a while maybe it is just the way it is. But I think there is more to it than that.

I just took a look at the motor mounts. I have the two front ones in stock V8 location and the two off the bell housing area (not transmission, I have not looked at them in the last 18 years ) that are just big rubber blocks with a bolt and washer thru them. Those rear ones have different bolts in them. One side is a bigger bolt head and had two washers under it of different sizes. The other side has a smaller head and a metal rectangular plate on it. The rubber looks good. I believe I replaced them about 20 years ago. I will have to start keeping a better log of replaced parts. But at that time one was missing a bolt so I found a replacement bolt but should have changed them both out to be the same I guess.

The front mounts I replaced the rubber on about 3 years ago. At the time they looked the same when I got done. But looking at them now the drivers side larger motor mount cushon that sits on the top of the lower L bracket is thick and the one on the passenger side is thin. The parts catalog shows them both as thin and the outer most top and bottom are smaller but thicker, those look normal. But I am concerned that the drivers one is thick. That would make the motor be uneavenly mounted and could cause it to pivit on that mount since it would be higher/taller than the passenger side.

I guess I should buy some more cushions from classic parts. Maybe get some new rear mounts as well. I see they have some Polyurethane rears with plates on them that look good.

That may help my chatter and jumping cab issue.

Is it normal that they would wear/compress that way? Is that just from the engine torque? Or should they always look the same size on each side?
