E-Locker not engaging after axle bearing replacement

[Cmayer]

As the title says, e-locker worked fine before replacing the bearing and seals on the passenger side axle.

I've read of clocking the e-locker motor if it has been removed, do I need to do the same if the axle didn't go in the same exact splines as it came out of?

Cmayer, crazy - but I just posted the same issue. Very specific post coincidence. I'll stay tuned here as well.

Just read your post. Sucks about the crap service from the dealer. Once it cools down a bit I'll jack up my 4runner and make sure the diff has fluid as well as spin the individual tires while trying to engage the locker. Just seems to much of a coincidence.

Jacked up the truck, 4low in neutral, press lock and nothing happens except the blinking light; can't hear or feel the motor trying.

On to the threads with electrical trouble shooting assuming the abs wheel sensor wouldn't have anything to do with it as that's that only electrical touched during wheel bearings.

No check engine lights or other issues.

ABS is disabled when in 4LO so that's not interfering with your e-locker engagement. Your differential doesn't care if the axle shaft goes back into the exact same splines. If you have the rear axle off the ground and spin one side of the axle and the other side spins the opposite direction then your axle shaft is engaged to the differential. (Assuming you are in park and 2wd.) You most likely have an internal problem with the elocker actuator. There's a couple threads about it including a "rebuild/service" thread on the elocker actuator on here if you search around.

Thanks. I believe you're right that it's an internal issue. Drives fine and everything else works perfect with the 4wd system; awd, 4 hi, 4 low, etc.

Only one pin at the locker shows power with a test light when the button is pushed it flashes the test light and when the button is not pressed the test light stays solid.

It's easy enough to pull the actuator and actuate the locker by hand, then you can determine whether your problem is in the axle or not. While it is off you can also see if the actuator does anything when you hit the button to isolate the problem further if need be.
