Unhappy Front end vibration help!

I'm getting a vibration (shimmy) through the steering wheel and floor whenever I'm going over 70mph. I've had the wheels balanced already and the brakes have just been replaced (pads/rotors all around). The car doesn't pull in either direction so I'm kind of stumped as to what might be the cause.
It's really irritating the heck out of me.

Were the wheel road forced? They can be in balance, but still cause shaking. Are the wheels bent at all?

As far as I know they aren't bent. A little rash on the sides from parking but I can't clearly see any dent or bends. I took it to sears since they mounted my tires a month ago and gave me free lifetime balancing for the wheels. I doubt sears roadforce balances but..... Would that make that big of a difference?

Also, tire pressures are correct. Could a bad end link cause something like this? Normal city driving is fine but at highway speeds the steering wheel just vibrates in my hand and the front end just feels loose.
I should mention too, that the car doesn't seem to be taking bumps as well either. I only have 59,xxx miles on it.

I'd start by putting the car up on jackstands and giving all the suspension bits a good tug to make sure they aren't loose. whack some stuff with a rubber mallet. check your swaybar mounts and endlinks just for ****s and giggles.

Beyond that I'd say take your wheels to a more reputable shop and have them balance them. I've had wheels done at the local Goodyear Tire shop and ended up with the symptoms you describe. After shelling out for a proper shop to balance the tires syptoms went away.

Hope this helps. good luck.

I'm not seeing anything wrong with the wheels off. Nothing looks bent, broken, or loose. Gave everything a tug and it's all solid.
I think I have an idea..
When my brakes were done, the drivers side pads were worn out almost down to the backing plate, but all of the other pads still had maybe 30% life left. We thought the caliper was seized but the pistons went back in. Now I'm unsure of if this could cause the problem but I am hearing a light scraping sound as well, like the pads are rubbing the rotor, especially when I'm turning at lower speeds.
If the caliper is seized, could this cause my vibration at higher speeds? I'm having a sinking feeling that this is the cause of my problem...

Put the front tires on the rear and rear on front. Vibration goes away then its a wheel/tire. If not keep investigating. still there? Get an alignment check. The lasers will tell you a lot that your eyes can't see, ie; wheel bearing, tie rod.

Everyone seems to think this is a wheel problem where as I'm leaning more towards my possibly stuck caliper

Yes we are. That is what you check first to diagnose the problem. Have you rotated your wheels and test driven the vehicle yet? With a stuck caliper you will get a pull to one side. ROTATE THE WHEELS!

I did rotate the wheels. No change in symptoms. I'm really lost on this one.

I don't even know why I'm posting in here again. Get your alignment checked and tell them your symptoms. Are your tires showing any sign of abnormal wear? Cupping, feathering, the inside or outside wearing faster then the rest? If your not sure take it to a shop before a wheel falls off going down the hiway. There is a lot the machine will see that we can't. Maybe its your inner tie rod, or the wheel bearing. Both things that could cause more damage if not fixed now. If you keep driving on it you WILL cause abnormal tire wear. And you can't just replace two tires like 2wd. It is cheaper to fix problem Z, rather than problem Z and four tires.

Hello,

Did you solve this problem, I have similar situation
I have WRX SW 2005 at 50k I started felt vibration on the steering wheel and I changed pads(necto) and rotors(Tarox drilled), also front left bearing, and at the same time I changed the Shock aborbers for one Kayaba regulable in 4 postions. After 1k I started to feel the vibration on the steering again and in the pedal while breaking, also feeling of general vibration in the car. I change a new set of discs(Tarox ones), after 500km same vibration again. Third time I installed Original discs of the Subaru, after 200km same vibration, and the vibration is now in the gas pedal, mainly between 3000rpm and 4000rpm, also while braking the brake pedal has vibration decelerating at some speeds mainly 60Kmh, the vibration is heavy really heavy, is like if anything has unnormal iner time, also general vibration is present in the rear part. I have change also front bearings and the frontal hub units. We checked the dics everytime we changed and all of them has ovality around 5-7mm... All car is aligened, also tires balanced.Obviously the problem is not in the brakes..

So did anyone ever get a resolution for this? I've got an issue just like it. the tires have been rotated - rebalanced with the issue still being the same also new calipers were installed along with my last set of rotors and pads. Wondering if anyone had any futher troubleshooting I could do before sucking it up and taking it to a shop

Did you have them match mounted(or road forced checked whichever you want to call it) like it says in post #2(I know this thread is 3 years old)

this type of vibration is a common issue with aftermarket wheels that have a larger center hub bore than than the factory hub. if using an aftermarket wheel, make sure that it comes with an adapter that properly centers the wheel on the hub or even better has the correct bore to start with.
