SO i have looked and looked.
 

Ok guys I have looked and searched over everything. My car is shaking or wobbling when i accelerate, around 60-70, and when braking.
acceleration-not so bad
60-70-real bad especially around 65
braking- real bad too

I have balanced tires, got alignment and rotated tires. Rotors are new BUT I'm thinking the caliper on the passenger side is bad. (sometimes I "think" it pulls to that side)

Any help on whats causing the wobble/shake.

And how hard is it to change out a caliper. Im guessing not to bad but is there anything specific I should know (I've changed pads/rotors)

its pretty damn easy. i can do mine (as long as the parts i get are quality) in like 30 minutes.

the hardest part is bleeding them, which, thats still pretty easy. get a one man bleeder kit (like $8) and a quart of brake fluid.

mine used to do that exact same thing...then i got new pads and rotors for the front and everything was perfect

i saw you said new rotors...did you also replace the pads?

do you have aftermarket wheels? is it the correct bolt pattern? or is it 5x114.3mm, if so, then do you have hub rings w/ them. If not, then that will cause your vibration issues.

this is for your 60-70mph shaking issue. Since you said u got the wheels balanced. Normally it would be a balancing issue too at this speed.

new rotors AND pads...

And i have stock 16's..

Its really starting to tick me off Im about to just drive this mother off of a cliff. I took it to a mech today and he said he had no idea.

Im thinking caliper is sticking, which caused rotors to warp. ORRRR struts are bad.

Any other info or ideas?

Update*

Still need help.

so far done---

Alignment
All 4 wheels and tires balanced and checked (for warp or broken belt)
Drove with new set of wheels and tires
New Tie rod ends front (is there any in the rear, dumb question i know)
Rotors have about 30k miles on them (wobble was there before the new ones and after.)


So I have the "wobble" STILL. To describe it, it shakes at all speeds and through acceleration and braking. I can feel it in the brake pedal and steering wheel but, it never really gets worse. You can hear it when you let off the gas it follows exactly with the speed of the rotation of the tires and is kind of a wouw wouw wouw type noise not loud or annoying, its just there. I did have one bent rim about 20k miles ago but has been replaced.

I have an 03 v6
16 inch stock rims wrapped with 225/50 kumho ecsta ast
106k miles.

Help.

was it like this before the new rotors??

warped maybe???

i still say swap the calipers out.

mine was doing that, and its perfect now. (besides alignment being off a tad)

If you had said "wocka, wocka, wocka", I woulda recommended getting your Fozzie tie rods replaced (those are the ones in the rear, to answer your question)

lolz:haha:

well the noise is really hard to explain but when i say what you just typed it sounds like that. I'll prob go ahead and replace the rear tie rods and the sway bar connections front and rear...the rubber looks pretty wore out.

I'll go ahead and get some new calipers because i think the pass. side might be sticking (drums in rear btw) I'm also gonna go ahead and get some R1 cross drill/slotted rotors at the same time as the calipers soo hopefully that will fix it...

Im thinking maybe struts? or strut mounts?

would an inner tie rod cause the problems..

What about engine mounts...just to throw something out there.

they should be good...I've taken them off recently to replace the belt and they look and feel fine.

mine was doing that too, turned out the caliper was leaking.

Driver side CV shaft is bad....going to switch that now..I'll let you guys know if that was it....so if anyone gets in my boat they'll know.

ended up not being the CV shaft....so now the gm dealership mech says front engine-tranny mount?

IDk..

also will the replacement bushings from PFYC fit the stock "sway bar"

we have a stock sway bar?? :huh:

looks like mine does...

Where do you get new bushings to replace the stock bushings...how bout that.
