Well on further inspection my left rear wheel bearing is going bad. So instead of replacing the bearings I am just going to upgrade the axles. I am thinking Yukon but am looking for recommendations.
literally one of the easiest jobs you will do is rear axle shafts. Getting the ones from NR with the seals and bearings already pressed on makes it a 20 minute job plug and play job. and yes that would fix your your seal problem. it is odd your leakage stopped because leaks don't fix themselves. maybe you were running too much gear oil or your vent was plugged.Timely thread, I've got a squeak developing in the rear passenger wheel area, currently only makes the noise sometimes when turning left when that wheel is loaded more heavily. Squeak sounds like it's timed with wheel rotation so makes me think it's a wheel bearing. No squeaks just when bouncing on that corner of the bumper which also makes me think it isn't a suspension component.
I also had some minor seepage of gear oil out of that seal quite a while ago, intended to have that fixed under warranty but never got around to it and never had any more leaking. Maybe that was a bad idea and contributed to bearing failure? Not sure if it could be connected, haven't yet looked into how that whole axle/hub assembly works back there and I'm all new to working on vehicles in general so learning as things come up.
I'm still under the 3yr warranty so guess I could try to have it replaced that way, along with the seal, if dealer doesn't hassle me for the bigger tires. Seems unusual for a wheel bearing to go bad at only ~23k miles / under 3 years, with only small/light 35s for about half that mileage. I'd hate to replace it with OEM parts only to have it fail again soon. I do drive on a lot of twisty roads and take the turns at a brisk pace so I suppose maybe I put more wear and tear per mile than an average driver, but I don't do much of other things that may be harsh on that area like river crossings...only been across a couple streams deeper than the axles.
If I were to decide to deal with it myself and use better aftermarket parts, would something like that 10 factory axle shaft set from Northridge be the ticket? Is that a pretty easy install? Would that cover my suspect seals too, already all included in the built up shafts? Was also thinking about doing the Dynatrac BBK so could do it at the same time, with the brakes off. And unlike Terry I have no plans to upgrade my rear axle so wouldn't be a waste.
The leak did occur after hammering up a long hard grade out of death valley in the summer heat, around 115F. So gear oil temps would've been as high as they'd ever get. And it wasn't leaking at rest, just had some residue around the brake rotor shield from leaking while running.literally one of the easiest jobs you will do is rear axle shafts.
