Grease through A.B.S. port confimed!
 

Just wanted to let you guys know that you can grease the front hub assemblies through the A.B.S. sensor hole without throwing a code. I used a rubber tipped air hose fitting attached to my grease gun and pumped about 20 pumps into each side. I know my bearings are on the way out and I'm selling it soon. The results are a night and day difference. The rumbling was way down and the next time I replace hubs on any vehicle I will give it a few squirts before I put them on the vehicle.
