    Service 4wd light

    Yea I saw that one, he’s got some good info in there but his selector switch only had three buttons, mine has four so I’m not sure if those procedures or anything would work on mine, it’s all above my electric pay grade too Sent from my iPhone using Tapatalk

    Service 4wd light

    Yea I’ve looked through most of the vids but haven’t really found anything useful that doesn’t involve a scanner. I do remember that it didn’t start doing this until I jiggled some of the wiring a while back, before changing the tc, so maybe I should take a hard look at my connections and the...

    Service 4wd light

    A few weeks before I replaced my transfer case the light would show up every now and then, I thought that maybe after replacing my transfer case (which I was going to do anyway) it would stop coming on, but it doesn’t. It does go off after I turn off the truck. I have been paying attention to...

    Need a transfer case

    Got my transfer case rebuilt, needed clutches and chain, but also had them drop in new steel cage bearings a new pump, seals, and a new heavy duty aluminum backhalf, and new speed sensors, all total $500 ($200 of that was for the new backhalf) their completely remanufactured units are about...

    Since the transfer case is out decided to clean up the transfer case wiring and added new speed sensor plugs and finally put new universal joints for the rear driveshaft, front shaft is already done Sent from my iPhone using Tapatalk

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    Yea I agree, it’s hard to find. This is actually a pretty big company here in dallas, they do everything from engines to front diffs, and each part of it is handled by in different departments, so a guy that usually builds heads won’t be putting together a transfer case. They were gracious...

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    Dropped off my transfer case, they pulled it apart in front of me and checked it all out, so it needs a chain, pump, clutches and they’re going to replace the plastic cage bearings with bearings that have steel cages, new seals, new heavy duty aluminum backhalf, and new speed sensors. They’ll...

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    Well since it’s been super hot here in Dallas, (it was officially 108 today) and I haven’t been able to run the ac unless I’m flying down the freeway (which sucks). I’ve been doing some changes, first off changed the coolant, then today pulled out my efan setup, got rid of the sheet metal...

    Abs delete and autotrak transfer case

    I already have, I’m running Powerstop drilled and slotted rotors with Ceramic pads, all new stainless steel braided brake lines new calipers etc. basically the only thing that has not been changed are the hardlines and the abs module itself, everything else is brand new. I’ll tell you though...

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    I’ve got a 140 amp alt and I upgraded my wiring to 0 gauge grounds, and power cables. With everything on including 3 pairs of auxiliary lights and efans and and 4hi mod at idle I’m at about 13.7-13.9. Of course I do have a second battery as well Sent from my iPhone using Tapatalk

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    After having issues with my 4wd, went ahead and put back my abs module, figured out a way to kind of bleed the abs, just have to bleed the brakes some more and then I’ll take it to a shop tomorrow to have them do an abs bleed and bleed the rest of the brakes and see what I end up with...

    Abs delete and autotrak transfer case

    So after googling np246 and abs, it does seem that the two systems are intertwined, atleast the speed sensor parts. My only real concern is if I will have to ditch my proportioning valve and put everything back to stock or if I can just use the sensor side of things. Since the abs is only...

    Abs delete and autotrak transfer case

    Hmmmm well my speed sensors in the front are inoperable, the abs module is not in the truck anymore since deleting the abs. Good news is nothing has been cut or destroyed so maybe I can just hook up all the wiring and see if it helps? Sent from my iPhone using Tapatalk

    Abs delete and autotrak transfer case

    I’ve been looking this up before I drop $950 on a new tc, I found an old discussion from 2012 on gmc4x4.com where a guy says the tc has 3 vehicle speed sensors, one at the tailshaft, front driveshaft, and another that goes through the abs via the wheel speed sensors. Is this correct? Does it...

    Abs delete and autotrak transfer case

    Yea I get it, the abs on these trucks is part of the reason for poor braking, never seen one that will stop very good, I’ve done a lot of research on fixes and tried some, the only way I could actually achieve any kind of stopping power was to delete the abs, nbs master cylinder, stainless steel...

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    After I got off work noticed my brakes were a lil squishy, thought I blew a wheel cylinder but turns out it was the brake proportioning valves front equalizer decided to squirt fluid all over the engine bay and not to my brakes. So I drove 35 miles in stop and go traffic in 100+ degree heat...

    Need a transfer case

    So I’m guessing this is not good, I was about to pull the shift encoder motor and try a different one just to try and save $850 for a new transfer case, and I was moving the front driveshaft and noticed about 3/16in of vertical or horizontal movement from the output shaft, I have a video but...
