Does anyone have any tips for getting the wheels off? I guess my 2 front ones are fused/rusted to the rotors. I shot them with PB Blaster numerous times over a time span of 3 hours and they still wont budge. What else can I do here?

Sit on the floor and kick the tire with your feet. They are rusted to the hub, not the rotor and this is pretty common with BMW's hub centric wheels. My e30 did this until I sanded the hub and painted them. Never had the problem again.

Not trying to make you sound stupid, but are you positve the wheels are COMPLETELY off the ground?
No offense taken, but yes the wheels were 100% of the ground..

I didn't go as far sitting on the ground but I was definitely kicking the wheel trying to budge it. I kicked it as hard as I could without breaking anything (Sounded like various parts were rattling around in there).

And I did lower the car on the wheel without any lugs. The thing supported the car like it was lugged. I could prolly drive around on the friggin thing without the lugs- it is definitely fused on there..

Brings me to another point now. I wanted to change front pads and rotors. When I finally get the wheels off, the rotor is sure to be fused on even worse? Or is this just a wheel/hub kind of problem?

There is nothing weird about it. The Hub gets wet and rusts to the wheel, if you kick the tire with both feet while sitting looking at the wheel usually it will knock it loose. I could not get one wheel off my e30 and had to take it ti Les Schwab, they hit it with a rubber mallett in the same places I had been kicking and it came loose. Use a wire brush and clean the area well, then paint it allowing the paint to dry.

It is NOT the rotor, like I said. Your wheel does not touch the rotor, it is the hub!

Thanks for your help, I will definitely clean that area nice and good. I understand the wheel rusts to the hub but what I mean about the rotor tho, will that also be "stuck" when I try to remove it?

Your rotor should have nothing to do with the failure of the wheel to come off. However frequently the hex bolt that holds the rotor on the hub will rust and can be difficult to remove. I found on my 318 that it was easier to have on hand several of the hex bolts and than to just drill the one currently on the rotor off. It is easy and they spin right out once drilled. I than install the new rotor and install a new hex bolt. CAUTION make sure that you use a drill bit that is small in diameter than the hex bold so that you do not drill into your threads.

i think he was agreeing with you BigD


and you are right in saying that its the hub thats its frozen to not the wheel. BUT he brings up a good point, if the wheel is frozen/rusted on then i can imagin the rotor retaining bolt will be reallllly stuck in there.

buy an impact driver ($20) with a 3/8in end and get a 6mm head for it. the impact driver is this hunk of metal with a cam inside of it, and when you get the 6mm allen in there you just whack the driver and it will deliver up to 200ftlbs of torque to loosen the retaining bolt.

but thats only after you get the caliper off which won't be no thang.
