    Rear axle seal job

    Let's start with this question: Where exactly is the oil leaking from? Then we can tackle what parts/tools you will need. I'm sorry, but your description of the problem is a little vague, please be more specific.

    1996 Parking Brake equalizer

    Here is my equalizer with new brakes and new cables. The amount of screws thread exposed on the front side of the adjustment nut is1.5 inches. Sorry for the dark picture. I may take another one this afternoon. Thus should at least give you a good starting point. Sent from my SM-N975U using...

    Tried Bleeding ABS, ran into an issue...

    What do you mean by no success bleeding each caliper? That is definitely the first issue. I assume you are holding the pedal while the ABS is bleeding itself? Can you hear the electronic motor run? Sent from my SM-N975U using Tapatalk

    1996 Parking Brake equalizer

    I haven't changed to a different equalizer, but I can tell you that the cables are very susceptible to rust and not allowing the cable to move. The second area of concern is how they routed the cable along the frame. I can't speak for the STD cab, but on my ECSB I made a modification to the...

    96 Suburban ABS Module - unfixable and unsure what to do

    The current scanner you have is capable of 90% of what a DIY might need. The factory GM Tech 2 scanner(or Ebay Clone) is capable of doing some additional engine control functions for your year, as well as communicate with the ABS module, the factory Delcotron radio, the SRS(Airbag) module...

    96 Suburban ABS Module - unfixable and unsure what to do

    After doing a little research, your Actron Scanner is NOT capable of pulling ABS specific codes from your truck. It may pull them from a 2000+ vehicle equipped with CAN functionality. This does not mean that your ABS module isn't communicating, it's just that your particular scan tool lacks...

    Master cylinder problems 99 Suburban, HydroBoost and EVO.

    Can you provide some part numbers from RockAuto of the master cylinders you have purchased? There are some M/C rebuild kits available from GM/ACDelco that have the primary piston and seals.

    96 Suburban ABS Module - unfixable and unsure what to do

    Can you provide clarification on what you mean by "everything points to a failed ABS module" ? What has been checked, what makes you suspect the ABS is at fault? What sorts of troubleshooting has already been accomplished? Do you have a factory manual? Have you followed the troubleshooting...

    96 Suburban ABS Module - unfixable and unsure what to do

    Before you go chucking the whole unit into the garbage, you need to get access to a high level scanner, be it a dealer Tech 2 or clone. I'm sure a Snap-on, Matco, or equivalent would work too. You need to know if it's even capable of communicating and for our year, it's not CAN bus. That's...

    what Proportion valve to use

    I'm not completely sure that you would have to change anything with a rear disc conversion and factory equipped ABS on a 97. The ABS functionally takes the place of a proportioning valve. Your truck should not be equipped with a proportioning valve just like my 1996 is not. The casting is...

    ABS DTC C0221

    I pulled a junkyard ABS module apart just to learn about how they function. The super short version about why rebuild companies won't touch them is because the unit is sealed with a small amount of vacuum and some extremely tough encapsulation epoxy. They have a small packet of desiccant...

    Brake Lights Staying On

    How old are your parking brake cables? It sounds like they might be dragging pretty bad like mine were. Over the years,the cables develop a lot of corrosion between the outer steel spiral wrapping and it squeezes the inner element causing excess drag. You either pull up the pedal with your...

    Suburban rear axle into C1500?

    The speedo is calibrated by changing jumpers in the DRAC, Digital Ratio Analog Converter. https://harristuning.com/Tbi/vssb-drac-calibration/ Sent from my SM-N975U using Tapatalk

    E-brake light

    Pull the E-brake release while simultaneously pulling the e-brake pedal back with you're foot. If the light goes out, it means that there isn't enough spring pressure to fully disengage the brake pedal. Normally, this would be caused by parking brake cables not adjusted properly or in need...

    ABS light on after getting up to speed

    I don't know what the Chinese have to do with your problem, but I would measure your wheel sensors at their respective connectors. Off the top of my head, the resistance should be somewhere around 2000 Ohms, but don't quote me on that.

    ABS KEEPS IN GAUGING

    A cracked reluctor ring or mismatched tire sizes can cause erratic signals to be sent to the module thereby engaging the ABS when it shouldn't. The brake switch "arms" the ABS unit for possible ABS engagement every time the brake pedal is pressed. On pre-'95 you should be able to read flash...

    What are these for?

    This is the schematic for my 1996. Also, my manual doesn't match my truck because there was an Tech Bulletin that upgraded the original THERMAL heated front axle actuator to a electric motor style. I think there was a short harness upgrade which is why my actuator now has a three pin connector...

    What are these for?

    I dont have my manuals handy, but the plug probably goes to the PCM and to the light on the floor shifter. My 96 illumates the front axle diagram when 4wd is engaged. Sent from my SM-N975U using Tapatalk

    Kelsey Hayes ABS control module 310

    I agree with this comment. After a bit of exhaustive detective work in my service manuals the other night, the reason that the Tech 2 is capable of scanning all modules(besides being a dealer tool) is that it has two separate communication protocols built into it. The first protocol is what is...

    Kelsey Hayes ABS control module 310

    FYI: the VSS sensor is supposed to read between 900 and 2000 ohms of resistance. The front wheel speed sensors can have a variable resistance reading depending on temperature. See picture. So if you are measuring a sensor when the vehicle hasn't been driven, the range is between 2420 and 3450...

    Pure electrical resistance. If the ABS module doesn't sense a specific resistance reading in any of the sensors, it will illuminate the light. Sent from my SM-N975U using Tapatalk
