Question about GMC K2500

1 Answer

Am replacing the steering gearbox on a 1996 GMC 2500 Sierra, 4X4, 6.5 Diesel due to a worn input shaft. On the worn gearbox it is noticed that the most forward of the two hydraulic ports in the gearbox has a restrictor or check valve in it. The rebuild replacement gearbox has this restrictor or check valve in the rear most port. Does the location of the restricted port matter and will it affect the gearbox function? The parts supplier said there is another gearbox available for trucks with a lower GVW, determined by six wheel studs (this other available gearbox has the restrictor or check valve in the same forward port as the one being replaced). However, the truck that this gearbox is being installed has eight wheel studs, leading me to believe it should be the higher GVW gearbox. Has the wrong gearbox been installed all this time? Does it matter which gearbox is installed? Does the location of the restrictor or check valve matter and will it affect its function?

I don't know but I suspect it will matter which port the restrictor and check valve are fitted to.

I personally wouldn't worry about the six stud vs eight stud argument. People tend to buy their own commercial vehicles and there are usually many available options that can be specified at order and fitted during production or changed later. The purpose is to make the finished vehicle more suitable for where it will spend the majority of it's time.

It is usually possible to buy a commercial vehicle with the "wrong" equipment fitted that is still in a proper condition... In my experience it is certainly not unusual to buy one sort of truck and uprate or downrate it in order to qualify for a different rate of taxation.

GM vehicles used to be fitted with a plate embossed with lines of groups of 2, 3 or 4 numbers that are meaningless to most people but when decoded tells the story of the vehicle options fitted to the vehicle - gear ratio, fuel and air filtration, suspension and so forth...
It is best to be guided by those and the chassis number and certainly fit like-for-like unless it is for an approved modification.

SOURCE: 1997 GMC Sierra Ignition Switch Replacement

take off the cover on the top and bottom of the steering column just behind the wheel. pop the tilt lever out simply just by grabbing it and give it a good tug. then once you have the new switch and you get in there your going to need an inverted torx socket to remove the small bolts that hold the switch to the column. do not move the gear on the new switch make sure it lines up exactly as the old one did!!!!!!!!!!!!

How do you drill out the ignition cylinder on a 1996 GMC sierra 2500 no key


You are better off taking it out from the inside of the steering column after removing the steering wheel. When the cylinder is rotated it moves a shaft that travels down the inside of the steering column that activates the ignition. There are on wires attached to the cylinder that will give you ignition. If you must drill it out you will need at least a 1/2 ins to 3/4 ins drill and that will butcher it.

99 GMC JIMMY. STEERING LOCKS DOWN SOMETIMES AFTER 1/4 TURN OF STEERING WHEEL. CHANGED PS PUMP, CHANGED STEERING GEAR BOX, CHANGED DRAG LINK, CHANGED BALL JOINTS, NO SIGN OF PHYSICAL BINDING WHAT IS...


Could be steering shaft on bottom of column that connects column to gearbox. Rag joint or u-joints on shaft are dry or seized. Try spraying rubber rag joint & u-joints on steering shaft with a good penetrating oil like PB Blaster. Work steering wheel all the way to left,spray, then turn all the way to right & spray some more.

I have a GMC Sierra 2500 with 4_wheel drive. I


Not sure if this year was a sealed hub like newer ones bt the process is the same. You need to take off the brake caliper, take off the caliber mount to the axle, then the rotor should come off. May be able to remove the stud now but if not, will probably have to remove the hub. It is bolted on to the axle with 4 bolts usually. Need to pop the cap off of the outside of the hub to access the nut holding the front axle shaft to the hub. It is splined shaft that is not pressed on. By tapping the end (lightly on the threaded end) and pulling out the hub will usually release it. Good luck!

2006 gmc 2500 vibration around 60 mph stops when I let off gas


Usually a vibration is due to one or more parts that have become worn or damaged. I'm not sure why you mentioned the tires but don't disregard them unless you know that they are fine. Check for correct inflation (on the door jam), for uneven tread wear, or bubbles and damage.
Other things that can cause a vibration is the front-end needing an alignment, a tire that is unbalanced, worn out steering components (like a wheel-bearing), defective u-joints and/or an unbalanced drive-shaft, or low gear-oil level in the drive-axle can cause damage to the ring & pinion gear. The damage would primarily be on one side. So when you let off the gas pedal the sound goes away. Check as much as you can and let me know how it is going.

I have a lot of play in the steering wheel


Provided as to wether or not your model has a steering damper (if smo, may likely need replacing) and the ball joints check good, it may be likely that you have a worn steering gear. Many types are adjustable or rebuildable.

2500 4x4 2003 GMC - When I push on the brake to turn a corner, I loose power steering until I give it some gas.


Sounds like a slick or worn serpentine belt or low level in the power steering pump. A bad belt will grab just enough at higher speeds not to impact the power steering or other accessories but not at lower speeds.
