help me... slove this problem

i have a 91 240sx and when i am going fast around 80mph.. and i tend to brake the car tend to shake... and back wheel tend to wiggle.... does that mean my rotor is mess up? our is it my wheel unbalance??? please help....

if your wheel was unbalanced you would only feel it at a certain speed. like say around 60mph it shook and then after acceling faster it goes away. if it just does it at higher speeds most likely it is your rotors.

bad tie rods can also cause/amplify the shaking

yeah forgot about that. it could be ball joins bent arm and such. just look over everything

If its only when your braking, its probably just warped rotors.

definitely... i had the same problem. i replaced the rotors and got the wheels balanced. The problem quickly went away.

Also if you check all of your bushings you may come across a few that need replacing... like everyone said look around and see what the prob is.

Is it just me or does this look like one of those crappy Japenese translations like on the JUN site?

"This bumper is made air space at the front bumper bigger than normal. It improves the cooling efficiency of the intercooler and radiator. It is considering for after parts (oil cooler,brake duct). It has the duct of both sides big, and adds an air duct to both sides. It contributes to the stability in high-speed-running because optimal down force is gotten by large-size rip spoiler.
*It uses normal winker. "

:dunno:

rotors for sure, check em

uhhh...shaks when breaking.. dz it shit to one side or just shake.... if it shifts and shaks then its the frame (mine was dented and its shifted and shook when breking) if not then its the rotors....change them!!
