How to properly operate rear diff lock

Wen I turn on rear diff I still only one tire spin. Does it work after a certain mph?

 

if you are a 4x4 you MUST be fully in 4lo before you can begine to attempt to put in the rear locker (unless you have modded the truck).

The locker is ONLY engaged when the red dash light is SOLID. if its flashing its not locked.

To properly put it in you MUST be under 5mph. I personally come to a complete stop (if you are a prerunner you need not do anything else, if you are a 4x4 you must be fully in 4 lo - no blinking dash lights). Flip the locker on, then SLOWLY drive forward in an a turn IN ONE DIRECTION, you will hear it click as it locks in (due to the difference in spinning rates of the rear tires allowing the teeth of the locker to line up in that turn you made going slow) and the light will go solid on a dash.

 

Read the directions on the visor and in the manual.

 

It's a prerunner

 

Is it a trd offroad?

 

The pic in his profile looks like TRD sport.

 

I think you have a trd spot.
Hood scoop and blinkers in the mirrors
And a few other things.
The sport addition does not have a locker.
Unless mabye you have a button In question?

 

I think it is

 

Yea there is a button

 

Did you buy the truck used? Maybe the previous owner put a diff lock button in the truck
Sports do not come with a factory diff lock.

 

Post a picture of the button

 

Lol sounds like a fake locker

 

Just show a pic of the rear diff

 

Also sounds like someone overlooked the search function...

 

Then it would be simple.
Put in drive.
Push locker button. Drive slow tell you hear a pop type sound and the light comes on, if there is a light. Should be red and in the right instrument cluster. It should also come on when you click on the ignition for a few seconds and then turn off.

 

I tried to activate the locker without doing anything else, just having it in 2WD. It just blinked and beeped, but didn’t do anything. I thought on a 4x4 TRD OR it could be rear lockered in 2WD, like a prerunner.

If it just blinked and then did nothing, I was completely stopped. Did I do any harm?

 

Nope only in 4 low

 

And if you try to activate out of 4LO then it will just given you the flashing indicator and do nothing?

 

Correct. Blinking = not locked

 

Yes
