Steering wheel shaking after replacement of Front CA's and Bushings

Just last weekend I replaced my Front Control Arms, Bushings, and Wheel Bearings. Now when I drive 55 - 60 mph and above I get a nasty shake on my steering wheel. This occurs without me applying any brakes!

When I apply the brakes the shake is bad as well... I am 90% sure that this is due to warped rotors because when I rotated the rotor I heard the pad touching a spot of the rotor, then going free, then touching again, etc... So I am almost positive about my warped rotor issue.

Just today I had an alignment done at the BMW stealership because I needed one anyways! I was hoping that the vibration was due to the variations in the tires pulling to each side because of very bad alignment after the CA and Bushing replacement... However it did NOT resolved my issue and I am now trying to figure out what to do next!

The questions is... Could it be WARPED ROTORS the reason for having such a nasty steering wheel shake at 55 mph and above?? (Keep in mind that this happens while I am NOT applying any brakes)

Or should I start somewhere else?

Everyone is welcomed to share their expertise.

Thanks,
Miguel

Do you have any slop in your steering rack when your driving?
The other possibility is that your tires could have come out of balance, could have lost a weight from the rim? Thats an easy check.

+1

After changing anything in the suspension or steering, you should definitely get the car balanced.

Also check tire pressure on a regular basis

first check the balance of the tires, then change the brakes.

Ok... I will be checking the balance next! Sometime in the next few days... I have lifetime rotation and balance on my tires so that would be cheap!

Keep your suggestions coming just in case balancing does not resolve my problem.

Thanks again... I love E46FANATICS!!!

Alrighty.... this is what resolved my shaking problem:

HUB CENTRIC RINGS

My suggestion to anyone who has AFTERMARKET WHEELS and shaking problems is to first check for the HUB CENTRIC RINGS. Its easy and CHEAP!!!! This hubs are usually made of plastic and can easily wear down to the point that they break. They could have also been removed by any tire shop who forgot to re-install them.

Also, anyone requesting help with anything having to do with suspension... If you have aftermarket wheels, make sure you mention it. It is something that many people including myself forget to mention. Even though factory wheels may or may not require this hubs, MOST aftermarket wheels do require it.

When you think about it... it makes perfect sense! You can balance a wheel or tire or whatever, but if it has considerable play or if it is not laying solid on the hub... then balancing it makes no difference because it can still shake especially at higher speeds due to the pressure.

Anyways... I just wanted to share my results with everyone. I hope everyone who has the same problem can benefit from my information.

**REMEMBER**
If you have AFTERMARKET WHEELS.... Check for that little plastic thing (LMAO) called: HUB CENTRIC RING or HUB RING
