4wd

  1. PatDTN

    Driving my '09 LTZ it felt like i had driven into a sinkhole pulling into a parking spot.

    I looked at my right front and everything looked fine. Hmm. Felt weird again when I pulled out. Next stop was the same thing pulling in. Hmm. I was able to pull through the parking spot leaving and it felt less weird. Back on a highway it was fine but it occurred to me that I had used 4WD last...

    99 OBS Tahoe 4WD system problems.

    Long story short I bought this Tahoe with the transfer case already blown to smitherines. I picked up a used one, rebuilt it, and installed it (along with replacing many other mechanical wear items). Then i ended up finding that the front actuator, T-case motor, and selector switch were bad...

    4wd to 2wd

    So I’m basically trying to make my Tahoe a 2wd for an easy lift, what would I have to do to make it where I can run a spindle lift on a 03 4wd Tahoe. As far I know just have to take out cv’s out and run 2wd hubs. Any info Is appreciated.

    No power to TREC Fuse

    Hi everyone, I have a 2003 Yukon XL 5.3 4wd. From what I can tell I have a pretty unique issue. When I bought it someone had jumpered a wire from the prime port (aux power for testing) to one leg of the TREC fuse so the 4wd would work. I figured this out when I tried to put it in 4wd and it...

    I'm looking for information and advice related to the Active Response 4WD feature that's offered in the Premium Capability Package. I live in Texas, but I'll be driving to the mountains in the snow with some frequency from year to year. I'm looking to get a 2022 Yukon XL, and I have to decide...

    Stuck in Auto 4wd

    3 month old 2021 Tahoe z71 is stuck in auto 4wd. It will switch to 4hi and then back but when I press the 2hi button nothing happens. I have tried being in neutral, in drive, moving and not moving. Nothing seems to help. Is there a work around or do I need to see the dealer?

    2001 Tahoe LS 4x4 build

    So just a little bit about my tahoe: it started out life in Texas where it was assembled. It must have lived life around there for quite some time due to the lack of rust before whoever had it decided to trade it in or what have you, because she ended up in Michigan for a while then came into my...

    Kicking into 4L with encoder unplugged

    So I'm at a loss right now with my Tahoe. I have a rear main seal leak and it's been leaking into the encoder motor. I cleaned and replaced the encoder ring once I found the issue but since doing so my tahoe kicks into 4L on it's own when starting the vehicle and putting it into drive. I have...

    GMT800 / GMT900 Brakes (03 z71 tahoe)

    Hey everyone, I have been trying to figure out the best bang-for-buck braking upgrade. I have an 03 z71 Tahoe and I need to replace rotors/calipers/pads/lines, it makes sense to upgrade the front brakes to the better GMT900 setup, especially because it appears to be a simple swap. I'll be...

    Wheels - 4x4 considerations and incompatibility

    hey forum, Just purchased a 05 Yukon SLT 4WD yesterday in pretty great shape. I really want the GMC 22837233 wheels but I can’t find anything saying they won’t work except for GM saying they won’t fit my Yukon. Is that true. What should I know that would tell me why they would or wouldn’t...
