2x4 TRD rear locking dif issue

Ok then, your first post might need to be edited if thats the case

 

I believe it is! my truck must be extra special. Thank you for your help, I posed in 2nd gen btw.

 

It's all good man.

Lets clear things up/

1. Does this "shaking" happen during he "process" of the Locker engaging and disengaging?
2. Does it do it when engaged?
3. Does this happen when the locker is engaged and going in a straight line? or only when turn the steering wheel right or left?

 

I never noticed the locker button nor knew my truck had it, I was in the drive way at Del Taco when my curiosity hit and saw that button and pressed it, now I am in this rabbit hole. Thank you.

 

The shaking happens when it is engaged and disengaged like the actuator doesn’t disengage it for a bit. Going in a strait line, between 1,2,3 gear lower RPMs 2000-3500. The shaking does eventually go away.

 

When the Locker is off, is Locker indicator light OFF when this is happening, or is it flashing?

 

Are you saying that you tried to engage the locker in 2nd and 3rd gear? Maybe the 2nd gen locker is different, but the 3rd gen locker will refuse to engage above 3 mph or thereabouts. Once it's engaged you can drive faster. It's just the transition that needs to be done at slow speeds.

There's not much need at all for the locker at road speeds unless maybe you are drag racing or drifting, but I guess that's sort of the point of a 2wd truck with a locker. I really have never fully understood the concept and you never see such a truck where I live.

 

it was in auto, if your going above 3mph will the locker have issues?

 

The light will be off.

 

I thought I was in the 3rd gen channel, so my words were in that context. The 2nd gen locker might behave differently as it uses a different actuation method.

 

I guarantee your issue is not the locker. Maybe u-joints, maybe carrier bearing, possibly torque converter

His truck is a 2007 prerunner. Not a very common config. Afaik there are no limits speed-wise on the prerunner trucks. Whereas the 4x4 trucks have the speed limits programmed in. The actuator / physical locker is the same for all 2nd gens
