well my rotors have been warped for what seems to bee forever but i just dont have the money to fix them yet its been at least 1 year since it started shaking and bumping but now the car shakes even when im not braking!! and i just got new tires a month and a half ago! and they alighned them then so what cooould be wrong? please help!

 

does it only happen while driving? Have you had the tires RE balanced

 

happens when driving and braking is worse but thats the rotors. the driving is resent. havent had them rebalenced. could it be an alinment issue? havent gotten that done in a about a year. how long should that last. and what does it fix and or do. im not quite shure the diff beetween alignment and balence.

 

Its not the ailignment. Alignment is what makes the car drive straight. Balance is for the tires and makes sure the rims/tires are balanced so there is no shaking.
It may be that your rotors are warped enough causing it, but not likely.

 

Fsttyms1 is right, you need the rims/tires rebalanced or you may have one or more defective tires. Vibration when not braking has nothing to do with warped rotors.

 

thx guys got the tires rebalnece today for free under the new tire warenty and woot it runs sooooo smooth now! also tried running at 36psi front tires and 34psi back tires and feels better too, ill do more experimenting. any other sugustions for fornt and back psi if theres no other load but me?

 

Well my rotors are warped too. I get vibration at certian speeds. The vibration changes so im sure its the rotors. Maybe true in your case too.

 

Shouldnt get any while driving only braking if rotors. If its while driving, id suggest having the wheels rebalanced

 

If your rotors are so warped to cause vibration while driving, you'll have to grab the steering wheel tight to drive at any speed, not just certain speeds, as well as risking shaking loose and wearing out other suspension components.

 

If you are only noticing vibrations over 45mph then I'd point towards your alignment, because only then will you start to have noticeable issues with vibration/shimmying etc. If it's occurring under that and/or all the time, first have your tires checked for certain. You could have a bad bead inside the tire causing a bubble, and you may either need to replace the tire or have it repaired.

Hope you get everything figured out!
