Rear pinion bearing replacment cost?

97 zj with dana 44 making grinding noise at rear right. Sounds like a brake pad is worn but it's not the brake. Grinding at about 5mph and up in drive and neutral. Through research I think it is either the pinion bearing or the carrier bearing. Does this sound right and if so what is the typical time required by a garage to do the fix? Thanks!!

I'm thinking a wheel bearing instead. A pinion bearing (front) will whine on acceleration and the rear will whine on deceleration. Unless the diff is empty or had a HEAVY shock load, pinion and carrier bearings are pretty indestructible.

$25 for the wheel bearing and about $150-200 for removal and replacement (2 hours).

Andy, you're not far off - I seem to remember it costing me between $3-400 for the job. Can't remember the exact cost, it was a couple years ago.

Find a place that does regears and go there instead, probably cheaper. Since changing the pinion bearing is basically a regear. You'll need to pull out the carrier and replace the pinion bearing and at that point you should change the carrier bearings as well. Just to be safe a pattern should be run on the gears afterword to make sure it is still acceptable.
