Couple of Brake questions.

Ford stopped using Timken bearings in the rear ends in the late 90's. Went to KOYO ones. They are worthless and are usually wearing the axles by 30,000 miles. I used to average 4 ring and pinion installs a week. Around half of the '98 and newer cars needed bearings. In 2007, my friend working in the county police maintenance garage told me about five of the newest Crown Vics being taken to a local test track for some "spirited" driver training. When the cars were inspected afterwards, every one of them needed bearings in the rearend. And no you don't have to pack them with grease either. But if you buy OEM bearings it couldn't hurt. They need all the help they can get.
I ended up ordering the FRPP Bearings & Seals.

My only questions about packing these things with grease is this.. It seems like it would disrupt the flow of the gear oil through the bearing itself if it was packed with grease, or does that not matter? Also, wouldn't the grease break down after "x" amount of time sitting & rotating in gear oil?

I just got a 3.73 Whine Service Kit and the only Koyo bearing was the tail bearing. The diff bearings were Timken, but I can't speak for the wheel bearings as the kit only came w/ the tail and diff bearings.
