I had the inner aluminium wheel seized on to the hub and no amount of pounding the tire with a sledge hammer was going to get it out. I also applied generous amounts of WD40. The truck is a 2004 and these aluminium wheels have never been removed since they were installed at the Freightliner assembly line. The winter salt used on roads creates tremendous corrosion. I used a procedure that has been recommended on BITOG a number of times. I drove the truck with this one wheel on and two nuts loosely installed and braked hard and I noticed that the wheel had rotated a bit on the hub. It is a hub-piloted wheel. Another five minutes of pounding with the sledge finally got the wheel off. You can see the corrosion caused by the salt. I installed the wheel after grinding off the corrosion and applying antiseize and also used this nylon wheel protector. Thanks, BITOG!
