Finally got my driver side rear wheel bearing fixed. This was so bad it was like I was driving on a dirt road at 60mph. The sad thing is that this is the second bearing to go in on the same hub in 2 years. If this one goes bad in the same time frame then my hub is going to need to be replaced. Big thanks to Erik at I.P.M. Auto Service for getting it fixed.
Next on my list is to get my passenger side front outer tie rod replaced. The boot around the end has gone missing and its creaking pretty good when you are going around a corner. Hopefully will have that done before our Christmas drive to Northeastern Oregon.
Lastly, my new front rotors should be in the mail soon. I got a pair of Power Slot Cryo Slotted Rotors from aspectuning.com. After researching for several hours, getting the Cryo treatment seemed to be a good investment. Our S4's seem to run into a lot of warping issues, so hopefully this will help. I'm going to pair them up with Akebono Ceramic brake pads. Several people from the forums have been swearing by these pads as they leave almost zero dust and perform very nicely. Hopefully these rotors and pad will be a nice combo. I should have a good review in a month or so.
