    Note: I had this issue (4HI blinking, and VSC light on), I disconnected my 4hi plugs off the actuator, re-seated them, and poof it worked again flawlessly. Lest we forget, the external plugs are subject to as much or even more corrosion than the internal parts!! Or maybe it reset something with the 4wd computer? This was after trying jogging the switch back and forth, forward reverse directions, slow and fast, full tilt steering, banging on actuators with rubber mallet. 4hi, 4lo, and 2wd actuated easily. I am definitely going to exercise these actuators more often! For a minute I thought I'd be in this close to $1000. (This is on 2012 Tundra Crewmax).

      Great feedback @bobadler3097 - Always appreciate the input from others who have had the same/similar issue. Helps build the knowledge base on how to affordably fix this common issue on this generation of Toyota’s.

    It’s not necessary to replace motor if it’s working, just pull the cover/motor assembly, leaving the gear set attached to the body. Twist the gear and manually force it into 4hi a few times to break everything loose, then reassemble everything and it should work just fine. Always unhook the battery first.

    • @pastorfred3460
      @pastorfred3460 ปีที่แล้ว +1

      Is the gear you are referring to the one on screen at 1:45? And if so, does the vehicle need to be in neutral? How freely should it turn? And if it is not turning, is spraying penetrating oil on it recommended? Mine will not go into the 4wd hi or low...thinkiing about tackling hi first. Also, what kind of grease is that yellow grease? I've not removed anything yet, nervous about making things worse but would really like to get the 4wd working...Thanks so much!!!!

    • @northwesttoyotas509
      @northwesttoyotas509  ปีที่แล้ว

      Hi Fred, yes, this is the gear the previous comment is referring to. I wouldn’t spray anything in there - you should be able to turn the gear and or pushrod slightly back and forth. The yellow grease is a Toyota specific type that if you call any dealership’s parts department, they should be able to tell you what it is if you explain where it’s located. It’s the same type they use on actuator’s in their HVAC systems and elsewhere if I remember correctly.
      I would also recommend putting the truck in neutral with the park brake on (naturally) and seeing if you can move the gear - also, try moving the selector switch on to 4Hi… good luck! Feel free to email me directly at jordan.c.jones@hotmail.com for more questions.

    At 4:25 the solder on the left looks good, but the one one the right looks like a "cold joint" meaning you got the solder hot but not the metal to which you were soldering, and that will likely fail and break off; the best technique is to place the solder iron tip to the metal part you are soldering to get it to temp, and then touch the solder wire to it, once it starts to melt then you will have a good solder joint!

    • @northwesttoyotas509

    My 2010 Sequoia would go into 4Hi just fine, but wouldn't go into 4Lo. It would only flash 4Lo. For some reason it did not beep at me even though it wasn't in 4Lo. I tested this by putting it on four jack stands, then letting off the brake while in gear. After going to 4Lo (not actually locked in) I couldn't get it back out of 4Lo, or 4Hi without turning the ignition off. When I turned the ignition back on it would reset the system for me and the 4Lo light on the dash would go out.
    I took the 4Lo actuator cover off and found that the contacts under the big plastic gear were rusted looking. I used a paper towel to wiped all the brown gunk/rust off of both sides. Then I smeared some of the grease in the case back on the contact strips.
    I wasn't too sure about the "clocking" of the gears, so when I pulled the case off, I marked a tooth on the large gear with a sliver Shapie and put a dot on the case. I also jumped the motor with a 12v battery to make sure it worked. I did this while I had the large plastic gear removed. In addition to that, I tested the micro switch for continuity. Before replacing the actuator on the transfer case , I checked the shift rod to make sure it moved freely, which it moved easily. After putting it all back together it works great now. It must have been the dirty contacts that were causing the problem.
    One more thing to note, my vent hose was still connected but looked very similar to the one in this video. I tried to pull on it to get more tube so I could cut the end off and re-use it, but it wouldn't give me any slack. I ended up pulling the hose off the other end on accident. I found out it was attached to an 1/8" plastic tube. The nipple on the actuator case is about 3/16". The two different sizes is probably the reason the hose end on the actuator nipples are cracking. I ended up using some clear 1/8" fuel vent hose and made it fit over the actuator. Hopefully it doesn't crack like the original hose did. It's not a hard job and maybe took me an hour to do, plus the time to get it on jack stands. You only need a 12mm socket, some extensions, and a good Philps screwdriver to get the actuator out.

    Great video. Im in the same boat currently. I'm working on the top motor/cover.
    Were you in 2wd/park when you began the project? What position was the actuator rod in when you removed the cover? was your gear set under spring tension when you removed it?
    my history: I was removing the transfer case and broke the vent pipe and electrical connection on top of the "top" cover. Im simply replacing the top cover. "simply" is an understatement. I've been cross-referencing videos to get a complete picture. my transfer case is out of the vehicle right now so the actuator is accessible. id like to get it set right before I put it back in. the original gears never came out of the actuator but they did release tension. Thanks for your help.

      To answer your other questions. I was in 2WD and in Park. I never got a picture of the stroke of the push rod, sorry. I hope you’re able to get enough of an idea on what you need to fix your issue. I did however adjust the stroke of the push rod on the lower (4-Lo) actuator and that was a source of a lot of my errors/issues.
