    Sarge - any other ideas? The shake is much better than it was before I cleaned & rotated the wheels & rotors, but it is still there. Sometimes it is worse than other times. It also changes based off acceleration/deceleration and sometimes is present when cornering.

    Is there a better way to check for bad wheel bearings?

    OK sarge, I'll get her to Eastpoint and see WTF is going on. I got a friend who works at Timken and he is going to try to find me a couple of new wheel bearings. If I get them for free I'll fucking change both of them regardless of them being good or bad. Thanks for all the help. I hate this kind of shit!

    The wheel bearing is a sealed assembly.

    Your wheels are hub centric meaning they are centered on the hub ring. So you would want to clean that surface rust off that ring on the hub and the flat surface area that the rim seats against.

    And believe it or not TQ wrenches do need to be re calibrated. So so yourself a favor and use a quality one that isn't 20 years old and in accurate as hell.
    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    icic...soo i did a pretty good job cleaning everything. i woulda done a better job cleaning it if i knew it was that important but all n all... what i did def cut the shaking down by 50%...soo what your saying is that i dont have to take the caliber (assembly) off at all and just clean the back of the wheel and front rotor part (hub) that the rim sits on right??? excuse me for i do not know these terms so well,lol...also i didnt use a torque wrench, but my friend has a good one soo i'll prob clean it once more and use the torque wrench. But what ft/lb again 90 or sumtin?? and in a triangular pattern??

    Yes make sure all surface rust and debris are clean around the hub "ring" which is the center where it protrudes into the wheels center.

    And yes the TQ is 100ft lbs. I have found best luck doing a 3 step TQ 50,75,then a 100. You want to go in a star pattern.
    It will also help if you are doing this with someone holding the brake and NOT with the weight of the vehicle keeping the wheel from rotating.

    awesome. im gonna do it exactly the way you told me and honestly i think its gonna be bye bye to wheel shake. i mean i cant hardly feel it as it is and that shit was ddddirty. Can you believe i couldnt get the friggin wheel off??? (mind you the lug nuts are off) ...it was like rusted or corroded on there... i used a rubber mallot, i even lowered the car half way with the jack thinkin the weight would break the seal..eventually i just started fore-arming the shit out of it and after multiple sprays of brake cleaner and ass whoopin it came off after 20 minutes...it def needed a clean,lol

    I usually lay on the ground towards the middle of the car and give it one or two good boot's from the inside and it breaks loose most of the time...........
    Also the trick to getting the rotors off is to pound on that hub ring while pulling on the rotor and rotating 90* and doing the same.

    Have you at least had the tires checked for balance? AT LEAST 95% of people that come in to my shop complaining of that is a balance issue or bad tire... that NEEDS to be your first step, its also very cheap...

    (if that has been said already I am sorry, didnt feel like reading all the posts)

    Sarge - So I finally got around to checking my hub's. I followed the instructions in the shop manual (remove rims, torque rotors down and apply 10 KG force - pushing and pulling). Both hubs are well within spec. I measured 0.002" total movement (the spec. is 0.008" max.). I still have the shake. Every time I remove the rims, it seems better for a while, but with some driving it gets worse. This makes me think that it has something to do with the rims and rotors. Maybe my torque wrench is bad? I will take my car to pedders, but I was wondering if you had any other ideas? Is there a better way to check for bad struts?

    One word of advice on eliminating frozen rims/rotors. I place some wheel grease on the hub/rotor/rim contact surface. So far, everything comes off very easily everytime. I don't see any reason not to do this, but make sure you use wheel bearing grease and not WD40 or something. You need a grease that will not burn off with some heat.
