ok, wtf is this shaking? So, I just got out of the movies, and my car is the sole car in the lot.. so I go to pull backwards, and give it gas, and my car goes ******* crazy. The front end is shaking up and down, all the 1/4's in my little change thing I was gonna use to wash the car tomorrow went everywhere... Its like the brakes were on.. What could cause this? I had the wheels at a angle, to swing the front around btw.

No clutch chatter, no exesive shakeing that I can FEEL, but I will have my dad sit in it and rev it while I look at it today.
Are motor mounts a easy, driveway install? What about tranny mounts.
I should go with solids right?

I would not reccomend solids at all for various reasons, especially if you like having teeth in your head. Go with polyurethane; stronger than rubber and not too much more flexible than solid. You can find them on Summit part # PTP-7-508-BL for $39.

I have a hard time thinking about it being the motor mounts... It did it again today when I was doing the same thing/
Start car ( already warm )
Pop it in reverse
Release the E-Brake
Roll backwards while reving
pop cluch
SHAKE
Yet when I do a straight 1-4 run, no shake at all.
Or when I do a regular doughnut, no shake.

Does it seem like a fuel/hesitation shake or a metal on metal chassis shake?
My car has a busted mount right now and a few months ago when this started, I couldn't notice the shaking in straight line driving or even in hard donuts, only when I turned slowly and more stress was on the mounts. Eventually I got clutch chatter at takeoff, and my clutch let out higher and higher. Now I can feel the engine move all the time. When I am taking a slow, sharp turn from a stop my car feels like it wants to shake itself to death.
To test a motor mount do this:
drive at 2000 rpm in 4th gear then stomp it, watch the shifter for any movement more than .75 of an inch.
OR
Put it in first gear and pull up the ebrake, let the clutch out slowly and have some one watch the engine.
OR just do what ever you do to make it shake and have someone walk next to the car and watch the engine.
If the engine moves more than it should, then it's motor mounts.
I doubt this is a fuel, catallytic converter, or opti related problem since you can drive normally in every other gear.

Mine was doing this, I didn't think of it earlier in my post, but mine was shaking real bad at start. Put in a forward gear, go forward, then put it in reverse, and see if it does it. Listen for a clunk in the rear end, or underneath when you do that. If it does, it might be the rear differential going out.

Oh if it is, Im gonna be up **** crick with outta padle...
I have 90 bucks TO MY NAME.
I will tell you what my, no car knowing self thought it was at first. I thought instead of the tires sliding around, they were skipping.. Could the fronts be over or under inflated and cause this? They look FINE on the outside.

That would have nothing to do at slow speeds. If you gunned it in reverse and turned the front wheels, yea, that would throw it around. But I assume you didn't do that... My guess is that is in the drive train. Sounds like the rear end. At normal easy take off it did it alot.

Its not slow speeds that this is happening at. Well, technicly it is, but I am going pretty much WOT in reveres with the wheels turned, what I was trying to do was a 180, and this hop accures each time... NOTHING happens at slow speeds, and NOTHING happens when I rip 1-4th gears, and NOTHING happens when I do a wicked doughnut...

dude, if you go WOT in reverse, your axle is going to hop up and down and shake everything. The rear control arms and the rest of the suspension are not made to provide traction in reverse, only forward.

lol, nice to know that now...
I was out to get me some dinner, and seen a empty parking lot. * ITS ******* POURING OUT! * so I figured, " If it is the tires skipping, it wont do it on this wet pavement " so I went to do it again, and the same thing happend...
So how are you supposed to do a 180? Should I look into LCA's and a PH?
