hey guys i dunno wats goig on with my car but it shakes at 65. i believe it just maybe that the tires need balancing. but i also found some tsb's about the steering shaking and wheels having run out and causing them to shake. any ideas on what can be causing my problem

" its going to blow up just sell it to me and be done with it"

you should listen.
 
thats wat i was thinking. i noticed today when rotating the tires that the tire rod and ball joint boots and had blown and are coming apart. i also noticed that that one arm that runs from the lower control arm to the rad support has cracked bushings. and the last and finally thing i noticed is that the boots on the struts have come apart. could all this cause the issue?
 
most likely tires arent either a) balanced or b) have uneven tread wear. shouldn't be an alignment because my alignment has been off for over a year and its never done that.
 
It's either tires, bent rims, or bad bushings up front. I highly doubt it's your brakes.
 
It's either
-Tire balancing
-Bad/Worn bushings in the front end
-Uneven tire wear, Cupping, caused by poor alignment or bad shocks and struts
-Bent rims
-Balls Joints are worn
-Bearings in bad condition, but would cause little to no vibrations.

If it was the brakes you would most likely feel it on the brake pedal.
 
mine did the same thing. then i got new tires (because mine were past their limit)
and it doesn't do it anymore.

if you have runout, you need an alignment whether that causes the vibrations or not.
balance your tires just to be sure, (it doesn't take that long)
and a busted tie rod boot isn't gonna do it, cuz my rod boots are blown, and my car stopped vibing at 65 when i changed the tires.
 
65 seems to be the magic vibration number haha.

Anyway, yeah - first check the obvious, the tires. If they're off balance or cupped, there's one problem.

Next is the TC rod's. If they're stock, they need to be replaced (or have the bushings replaced) because worn TC rod bushings WILL cause a steering wheel shimmy on s-chassis. I would recommend replacing the entire rod w/ an aftermarket adjustable piece since harder bushings have been linked to causing cracked lca's.

ive had 6 different cars shake because of warped rotors so its possible its the brakes only way to know for sure if it gets worse when you depress the pedal slowly ;)

ive had and have worn tc rods only thing they do is clunk when you brake hard or turn the wheel in place.....they never caused my wheels to vibrate or steering wheel to shake...im not saying its not possible just saying its never happend to me in all the cars ive owned

Mine did. A shimmy not a shake though.

BTW - this is phenomenon is actually visible if you watch anybody drifting on stock tc-rods.
 
its not the brakes because it stops when you hit the brakes. but there is alot of things worn down on the suspension setup so slowly everything is gonna be replaced with better parts

if a warped rotor is suspected, and you just happen to have access to tools in an auto shop/know a mechanic, get a hold of a runout gauge:

i know how to use one, but have never needed to.
