    '96 2-Door Tahoe Daily Driver

    Thanks! I need to remember to update my threads more often. This one is also a stainless Gibson catback - 615501. No drone so far, though I haven't had it over 60MPH yet, and I'm really hoping it doesn't. I have a Magnaflow catback and Magnaflow direct-fit cats on my Suburban and it drones...

    '96 2-Door Tahoe Daily Driver

    A better, wiser, more patient man than I would have certainly tried that. To my defense, the first one came off easy. The same amount of torque applied to the second broke the stud, and judging by the remains of the stud left inside the nut, the previous guy removed the last set of nuts with a...

    Phone Mount (95+)

    I couldn't find a good option to be honest. With a mount on the switch blanks the shifter was always hitting it, and there's not really another good spot. Instead I went and put in an Atoto F7 double-din Android Auto/Carplay unit and have been happy with it. I use the wireless AA for short...

    Decent affordable recommendations on brake control? For Towing anything from a few snowmobiles / quads to a Small car trailer

    Unlike these other bougie folks, I'm cheap. I don't tow with my GMT400s, since I have a diesel Excursion, but I just put a new Reese Brakeman IV in the Ex a few months back. Has gain and sync adjustments and works just fine, if you want something much cheaper than the other options that still...

    '96 2-Door Tahoe Daily Driver

    Another day of work on the Tahoe completed - new exhaust day! The prior owner had a custom exhaust on it. Workman ship was.. questionable, and clearly the elements were not kind to the mild steel tubing they decided to use. The rearmost hanger was barely attached, having been rusted all the...

    99 Suburban Overland Camper Build

    Yup that's next on my agenda - just need to get around to caring again and find the time. Time for the foreseeable future is going into the Excursion, 2 door and the house, hope to dig into it maybe late Spring. Sure, but like, valvetrain always ticks a bit on both of my 5.7s. No abnormal or...

    2000 7.3L Excursion Show-Off Thread

    In the last few months I've done more work to the Excursion than either of my GMT400s. The Ex got a new set of bellowed Riffraff Diesel up-pipes and, while the turbo was out, I threw a new high flow EBPV-delete exhaust housing, an EBPV delete pedestal, and a wastegate actuator on it. Also...

    99 Suburban Overland Camper Build

    Well this has been on hold for awhile now unfortunately. Before figuring out it was a failing torque converter making my weird noises, I thought it might have been the oil pump given the location of the sound, so I switched that out and added a steel pump drive shaft. Fired it up, had 60+ PSI...

    '96 2-Door Tahoe Daily Driver

    No pictures this time, but figured it's about time I got around to another round of status reports across my build threads, starting here with the 2 door. I did pull the dash and rebuild the HVAC box with new doors and actuators, heater core and evap unit. Got.. lucky? and the rubber ball in...

    Fluid leak behind master cylinder

    That unit behind it is a hydroboost unit - a brake booster that uses hydraulic pressure from the power steering system for power. Common in turbodiesels as there's no engine vacuum under boost. AFAIK, both of those parts have shaft seals there. You can leak brake fluid from the master...

    Trans Code "MX0"

    No idea - could it actually be 1SZ with a smudged S? I have 1SZ on my Tahoe, which the internet says is "DISCOUNT, OPTION PACKAGE" - "It is an internal code for “preferred equipment savings” or something like that, used across all GM vehicles that bundle features into trim level groups. It does...

    Trans Code "MX0"

    IIRC, MXO is a general code for an automatic transmission - you should have another transmission model-specific code to go with it, like M30 for a 4L60E.

    Wire connector identification

    And to also help these future people; there's a nearly identical one that plugs into the pressure switch on the accumulator/dryer on the passenger side firewall.

    99 5.7 shuddering/low power, no codes

    A new fuel filter never hurts. Your pressure might be a bit low, I think these Vortecs call for 60-66 KOEO and tend to drop into the 50s while running. Generally a failed regulator causes the pressure to bleed off after shutdown in my experience, so at least your new injector units regulator...

    R-134 leaks out one day after recharge.

    To add some additional info to the other posters; literally the only refrigerant-carrying part under the dash of these trucks is the evaporator. Both the input and output fittings of the evaporator stick into the engine bay through the firewall, so there aren't even any A/C line connections...
