Rear Diff Lock

On my 04 DC prerunner my rear diff wont lock in....i dont even know where to start, does anyone have any ideas on where to start?

 

Did you put your truck in 4lo? It has to be in 4lo to use the locker unless you did the grey wire mod.

 

its a prerunner.....

 

shit my bad...didnt read your info...I feel like a dumb ass now.

 

lol its all good

 

As a starting point, you might check the factory service manual (sticky in the 1st-gen forum) for the Rear Diff.

 

What are you doing to engage it and what happens?

 

just pushing the button....and nothing happens, no sound, no nothing

 

Usually you gotta roll forward (idle in drive) and you can hear it engage. When I first got my truck it took a LONG time for it to engage. Now that its been used (a lot) it engages a lot quicker

 

yeah i did that i let it idle down the driveway and idle back up in reverse and still nothing,,,, im so lost

 

Do it on dirt. It took me a good 30 or so feet until my locker engaged the first time I used it. Never try it on pavement.

 

well when i first noticed it yesterday i was in feild beside the house and i let it idle forward then back.... thats when i pulled it on the drive and did it lol

 

Does the Rear Diff light come on and blink on the dash when you push the button?

 

no nothing happens

 

Start out by checking your fuses, thats always a great place to start

 

The RR Diff is supposed to blink in the dash by the speedo and stuff until it works then it just stays lit up. Like TRD4x4858 said check the fuses 1st. Hopefully its something as simple as that and not a major problem.

 

ok ill start there thanks
