    I have the 07 TRD Offroad DBL cab 4wd with locking rear diff. I have had the truck less than a month and just tried to lock the rear diff in while sitting on the driveway. I turned it on and the liht just blinked and blinked. It never was just steady indicating it never locked. Any sugestions?

    Did it not just turn on when you hit the switch?
    Am I missing something here? This is a brand new truck. Why doesn't it just work.

    Not loving my taco

    you gotta roll the truck to get into 4x4, even if i want to go in 4x4 high, i just dont hit the switch and magic - it is mechanical and needs to be in place. you put in 4x4 high, then when you roll it will click in... all 4x4's are like this.

    then if you want it in low, you stop, put the clutch in, then flip over to 4x4 low... if it does not go in, roll a few feet and it will go on... this is when you put on the difflocker now.

    this is what i did the 4lo was engaged I rolled under power in both forward and Reverse. Then I hit the diff lock button and it still did not engage. I did all of this with the owners manual. I studied it and did it the way you described. It just didnt seem to work.

    Guess what. I'm stuck in about 18 inches of snow. When I switch to 4LO the indicator's blink and beep non stop. Truck goes up the 60 degree incline (way to get out) and then slides sideways towards a ditch. I think the 4x4 works but wonder about the 4LO. I also suspect the factory tires I have are not suitable for the snow. We've given up since its 10PM and will try again tomorrow. Where is that winch when I need it. Any input will be nice. :help: :pray: :ballchain: :frusty:

    You are in N when you turn on the 4WD?
    If not that buzzer goes crazy.

    No. I was either in drive or reverse when I switched. :confused:

    Don't remember reading that. Thanks. I will try again tomorrow morning. Also when I slid off the incline and I slamed the brakes, the ABS kicks in and the pedal then drops to the floors. Is that normal??? Very freaky.

    The pedal should never go to the floor. The ABS is very touchy on these trucks and make the most HORRIBLE SOUND EVER! In 4x4H the ABS goes off whenever the truck starts to slide. I took it to the dealership and they test drove it with me and said the noise was "normal"....

    In any 4x4 i have driven, Chevy tracker 2002, Chevy 2500HD circa 1996, Ford F-150 2006, Ford rangers (whatever i get to drive for work)... ALL require the truck to be in nuetral when you put 4x4 low on.

    I agree. It’s the worse sound ever. I thought something’s broken or hitting the ice. My Subaru never did that. Thanks for your input.

    it's always concerning when your 40k$ truck makes these very odd sounds. I just do not like how quickly the ABS kicks in, as it makes you skid even further

    Now that you mentioned it, I agree with you. It comes on too soon. May have something to do with the factory tires not being suitable for our winter conditions. :canada:

    the stock tires do suck pretty bad... every time i hit snow, the back end just wants to skid and fish-tail. it is funny they call them mud and snow tires.

    May be by California standards. It doesn't apply here. However, they are pretty good road tires. We have the sports version too eh.

    I thought you had the sports. My shocks do a nice job on the road. I need better wheels for our winter conditions. Thinking about some chains for now. I am yet to dig myself out of the mess I'm in. Too lazy to go out. :eek:
