EVO 8 Shakes Violently Under Throttle
and it's been that way for around 50,000 miles.
This morning I was on my way to work (15 mile straight road) and about half way through it I was creeping up on a car. I decide to give it gas and go around him and my car was shaking violently when I gave it gas. Feels like its coming from the front of the car. Feels like there may be binding in the drivetrain somewhere or something.
It feels like wheel hop. Tellin' ya. my ****'s been doing it for a month. Another guy had the same symptoms when his let go. There are other people on the forum that have had the same symptoms and same results.
Take it or leave it, but its easier to turn the boost way down to see than it is to track down some serpentine belt on a whim about a bent pulley.
dunno what to tell you, the stock clutch slips, yes, rpms go up, car goes nowhere. if you have a clutch with a higher clamp load/different kind of friction surfaces that can heat up and grab, it will rock the engine back and forth, violently.

It doesnt feel like wheel hop though, the car is being pulled left and right. And the clutch is freakin new, no launches, car is just a dd! The car only has a tbe, tune, and k&n drop in filter.
FIXORED!#!1!
First I ruled the power steering out, start with the easiest solution first. BTW after 3 trips to the auto store, its a 35" belt (part #350K6) to delete your power steering and ac.
Went for a drive and boy was the steering rock hard, even when rolling, more than it should be and it would pull to the right hard under acceleration but still yanking left a little under acceleration.
So I got to looking at the axles, I knew my tranny and diff were good, and I knew the clutch was good. All of the axles looked fine. I was like wtf. Well you could see a tad of what looked like grease spray by the passenger side axle. But it looked really old and it wasnt alot and the boot was clean. So I went ahead and pulled the axle and found about a 1" slit in it. It felt really slutted out when you turned it in the tranny too. Pulled it, luckily I had some evo axles laying around, swapped it out went and beat on it and it pulls smooth as ever under all variations of load.
