Rear E-locker to Air Locker.

You could, but it would take some electrical engineering. Ive read that it's pulse wave modulated. Even so it still would take the 10 feet half circle to engage it. I don't know for sure but the pre 2016 have an external motor for locker, that seems like it could be manipulated with a hot wire.

 

Sorry about the semi-threadjack, but I put up a new thread in the 2nd gen forum a while back and didn't get any response. Looks like the crowd here is the knowledgeable portion of tw about what I'm dealing with.

I've got a 2010 TRD OR PreRunnner that's been having some minor diff issues lately and I'm looking at a couple options for dealing with it.

The main issue is some wear in my ring/pinion set (rear end howling under power above 40mph), so.I know I need to at least get those gears swapped out one way or another. The other problem I'm seeing is the e-lock engaging on its own most times I get over 65-70 mph (not a problem with freway-level curves, but I often need to turn the engine off and back on at the end of ramps).

I'm considering switching to an air-locker and just replacing the whole diff, but wonder if it might be easier/cheaper to just replace with a new e-locker or get the problem diagnosed by a shop while having the ring/pinion replacement done.

I've got a 4WD trail rig now, and the PreRunner is pretty much just my daily/commuter and lumber/tool hauler for weekend projects now, so I don't wheel the tacoma and don't necessarily even need the locker at all and would maybe consider getting a real LSD swapped in instead as well then just use the diff lock switch spot for an accessory of some kind.
