Kestas,
When I said good old grease, I of course meant good old wheel bearing grease. I certainly wouldn't recommend wagon axle grease.I was simply trying to say I didn't think it was worth the money to buy rocket ship grease. Servicing the bearings at 30k is over kill, but it is your car and your time, so whatever floats your boat works for me. I am on the other end of the extreme. When a bearing starts growling, I take a look at it. A wheel bearing will usually complain for a long time before it fails. In 30 years I've only seen one go from making noise to total failure in less than 40 miles.
