Wheel bearings

Is it safe to lube the non-serviceable wheel bearings? I read that the ABS sensors can be pulled, and some oil(? Grease?) can be applied. The -coasting to a stop- bearing noise is driving me crazy.

It is a unit bearing, and sealed. So not much is going to happen in the way of lubrication. Are you sure your noise is bearing related?

The only part that can be replaced on the front wheel bearing are the studs. Nothing else is meant to be serviced. If there was a failure in the bearing seal grease would come out and cause the wheel speed sensor to generate an implausible signal. Are you certain the noise is coming from the bearing? Do you feather your brakes? If the front wheel bearing is failing then the bearing must be replaced. I'm going to switch my own front wheel bearings out with Spyntec manual hubs soon.

Front passenger bearing (hub) was replaced, the sound has quieted down a bit, but I can still hear it

I suppose it could be the front brakes with 38k? The rears were replaced at 35. It doesn't seem to be the pinion bearings.

Could the sound be the other bearing.. or the perhaps the new one is bad?

new one good. definitely the others, hence -would like to lucubrate but, if they are as sealed-a-unit -as mentioned above, then it's a pump-up-the-volume until they're bad enough to replace.
