I have a 1992 prelude with a JDM h22 and a regular h23 tranny.. It was driving fine until yesterday... 1st and 2nd gear redline okay and after i go to 3rd and i give it normal gas my car shakes really bad.. it also does it when im near redline at 2nd gear but i think anything after 40-50 mph my car starts shakin real bad and my steering wheel does to and when i brake it shakes too does anyone kno why?

 

It is either your wheel alignment is off OR it is because your wheels are not properly balanced...Both will only be noticeable above certain speeds.

But, you say it just "happened"... Did you do ANYTHING to the wheels? Like hit a large pothole, speed bump, etc... Run off the road?

In winter, on my 17" rims on my EG, the wheel weights would fall off roughly half-way thru the winter due to a mixture of hard driving, potholes/rough roads, and the cold. They were the stick on type for aftermarket wheels, not the clamp on type for use with factory wheels.

So, do you have aftermarket rims?

 

i have the stock si rims, well i beat the shit outa my car takin hard turns everytime thast about it and whenever i go over a lil messed up road it pull smy car to the side

 

Hmmm...

Well, its happening because something is not balanced correctly, be it the tires, steering or even an axle problem.

Look for the weights on your wheels (along the outer edge where the rim meets the tire) and see if any of them are missing...

Worst case scenario is just take it somewhere to get balanced...

But since you admit to driving hard, I would think it has to do with the wheel weights falling off due to more-than-normal aggressive driving...

 

get wheels balanced and have alignment checked. could possibly be bad axles. . did you hit anything. sounds wierd that it would just do it all of a sudden. are you redline all the time or what. just drive it normal and see what happens. if it still shows up after 50 then balance wheels. if doesnt go away then have frnt end chkd out.
