damn, every brake part is new! new rotors, new calipers, new pads, still shaking… it stopped for a while, but it has come back! this morning, I just replaced the right caliper and rotor, and it’s still shaking. left caliper is about a year old and the rotor was changed couple months ago. it’s shaking only when i’m braking.
could a bad tie rod end cause some shaking? because I know the right one as some little slack in it.
what else could it be guys??? could a wheel bearing cause this?
I had a simular problem few months ago. Complete brake job and replacement of front cv joints. After many trips back to the shop (brake vibration)…they replaced the front rotors and pads all over again…still the car shaked when braking. Finaly I took the car to a diff. shop and they diagnosed that the hub was out of sink (slightly bent). The bozos @ the first shop that replaced front shafts and new barings did not install it properly.
After a replacement hub …my teeth don’t chatter any more when I step on the brakes!!
If u have a gauge (like the one they use in the machine shops) it is very simple to check if u have the same problem.
UPDATE: at highway speeds, the car vibrates a little… but when accelerating, I can feel a pretty good shaking… I know I also have a bad left CV joint. could this bad CV joint cause the shaking?
how could a hub be bented? both CV boots were replaced not too long ago, could something have happened when I replaced them? when I replaced the right rotor+caliper this morning, I did checked them with a dial gauge, but they seemed fine…
but the weird thing is that the vibration came out of nowhere… it was not after something was replaced, at least, not that I can remember. it just appeared one day.
Based on the manual that I have (not naming any names:p), here’s what it says:
Shudder or vibration during acceleration
Excessive Toe-in
Incorrect spring heights
Worn or damaged inboard or outboard CV joints
Sticking inboard CV joint assembly
Vibration at highway speeds
Out of balance front wheels and/or tires
Out of round front tires
Worn CV joint(s)
Shimmy, shake or vibration
Tire or wheel out-of-balance or out-of-round
Loose or worn front hub or wheel bearings
Worn tie-rod ends
Worn suspension components
Excessive wheel runout
Blister or bump on tire
Erratic steering when braking
Front hub bearings worn
Broken or sagging springs
Leaking caliper
Warped brake rotors
I know that doesn’t answer your question at all, but one of those should be the culprit. I think there’s only a 5% chance that it could be something else other than what I mentioned.
Can you give us more info? How’s the wheel alignment and such.
the car’s alignment is perfect… after what you said, i’m guessing CV joint or wheel bearing… I know the left CV joint is shot and I’m pretty sure one bearing is also shot… I can hear a kinda whump-whump-whump noise when rolling…
i’m gonna have to check these… probably after x-mas… I don’t think i’ll have any time before next year!
The shop that corrected my vibration problem, advised me that damage to the transmission is very likely if the above prob. is not corrected asap.
Play it safe, and have somebody look at it (preferbly a shop that knows what they are doing).
Ps. I took my car to the reputable trans. shop.
They advised me that front wheel brgs are pressed into the hub assbly. That is where the first shop screwed up = damaged a new brg and hub assbly and trans. seals.
Like I said earlier, play it safe, have it looked at asap.
