Default Bad rear pinion bearing and options

Howdy all. I've had the "whir" in the rear end of my 2007 V6 4th gen diagnosed as a bad rear pinion bearing and I'm trying to figure out my options.

I've never given a ton of thought to air-locker's/e-lockers or re-gearing, but as I'll apparently be paying for a pretty pricey service, I wanted to get some takes on what everyone things the best bang for the buck would be.

I definitely use her off road and lockers were absolutely something I'd get on any new vehicle, so I'm intrigued by that option but also not entirely sure whet else it requires.

I'me running a 3 inch OME lift and BFG 275's.

Thanks ahead of time.

Regearing will require you to redo the front as well. Maybe see what a 3rd with a locker from East Coast Gear will be, most seem to have good luck with them.
ARB lockers are mostly used, but you can probably figure an elocker setup.
Or the cheap way is just to get a 3rd from a wreck and pop it in. Then redo your current setup as $$ and time permits. Swapping out a 3rd is not too bad.

It is not a replacement for a locker but since you said "bang for the buck" possibly consider the TrueTrac helical gear LSD (913A610). I'm pretty happy with mine and I like the fact that it works smoothly all the time on the road. It's been good in the abundant snow and ice we've had this year. There's a $50 mail in rebate right now too.

If you know you want a locker the Harrop ELocker is an interesting alternative to the more common ARB Air Locker. If I ever lock the front end on mine I'll probably use that.

+1 on the Trutrac. Less expensive than a selectable locker and more useful for daily driving. Given your location you will appreciate the improved traction in the snow. I'd only get a locker if you plan to do substantial rock crawling.

Your 4Runner has the 5-speed which has a pretty low first geat. So regearing is probably up to your driving style. But now would be the time if you wanted to regear.

I just went thru this a few months ago, see here http://www.toyota120.com/forum/showthread.php?t=29321.

I ended up having a local transmission shop do a rebuild with an OEM kit.
Cost me $1,200

If you have skills, space, and time I'm sure you can get it fixed for less.
