We're the company that serves you on the internet and in person. The locking of the two gears allows the axle to operate in the same manner as a semi-floating rear axle. The differential carrier assembly uses a conventional ring and pinion gear set to transmit the driving force of the engine to the wheels. While the light is blinking the electric current is heating the gasses. If you light continues to blink but does not engage or takes a long time to engage more than 10 seconds then this actuator is the problem. I hear a shift noise underneath when selecting Lo in Neutral , but no shift noise when selecting Hi.
That's going to plug in the same and everything. Threaded into the front axle is the front axle actuator. This actuator is needed for the 4 wheel drive to work. The actuator is probably not going to move. You may have one or two issues. Obviously, reinstallation is just the reverse.
We've worked hard over 11 years designing a website experience that makes it easy for anyone to idenify whether parts fit their car. Our manufacturer changed the mixture of gas in this new actuator so it is more sensitive at lower temperatures. Back side, near the top. You just grab onto it and rotate it counterclockwise. Leave the case in 4Hi and jack up the right front tire.
Took me longer to get the skidplates off the front of my truck than to switch the actuator. In this video we're going to show you how to replace the 4-wheel drive axle actuator on this 2002 Sierra 4x4. Check for power and ground if you have both when the transfer case is in 4x4 the replace the accuator. The axle identification number is located on top of the differential carrier assembly or on a label on the bottom of the right half of differential carrier assembly. They are available at most parts stores and are a very common problem. It is down on the front axle on the passenger side. You'r problem is all electrical trust me.
Often, these issues can be corrected by substituting aftermarket replacements, which often address defects and problems found in the original factory parts. The front wheels are not locked in as far as I can tell. If no voltage then the switch up on the transfer case is bad. The transmission place should fix it for free if it is something they did wrong. If you have voltage, and the actuator isn't working, it's toast. Make sure you get it straight in. Our switches are manufactured under a completely quality control process from componentry to finished products by experienced professional.
To figure out if it's you motor or transfercase, jack up the rear end, have a friend inside shift into 4 wheel drive, or try to, and put it in gear and apply some gas. Pull the front axle actuator. The actuator appears to be working because the front drive shaft does engage when 4wd is selected and rotates when the drive moves. Or the relay could just be faulty. We'll fast forward through putting the skid plate on.
Robust design and high grade materials meet the stringent demands of today's service professional. There are a number of things that can go wrong to cause you not to be able to engage four wheel drive. However, the 2014 model has had by far the most reports of issues, primarily having to do with sub-par headlights and poor visibility. These are 15 mm bolts. If the fuse is bad, the lights on the 4wd console wont light up. I then traced the wire to the top of the transfercase and tested both the end of the wire and also where it plugs into the transfer case.
Yes I can hear the case going into 4 lo so does that mean the transfer case motor is working? On top of the transfer case, toward the rear of the truck is a switch that has a 2 wire connector. Robust design and high grade materials meet the stringent demands of today's service professional. I seem to be having a similar problem with my 97 Silverado manual shift. Decades of industry leading research and development focused on meeting the technician's needs. Thanks 1A Auto I ordered this part and had it 2 days later. I bought mine from 1A Auto and never a problem sense. Fired up the truck and it engaged the 4 wheel drive instantly.
All it took though, was to take my old harness and wire it to the new shift actuator. I know for a fact that these will throw a service 4x4 code if they are unplugged or shorted. Online parts stores like PartsGeek. When I push the 4 wheel high or 4 wheel low button the light on the switch just blinks. When I hit the dash button for 4Hi it just blinks at me. Next, you're going to want to unplug the actuator you're just going to use a little screwdriver, pry up on the little latch and then unplug it. I would inspect it visually to make sure nothing looks corroded and also take a sniff of it to insure there isn't a burnt smell.
If the front driveshaft is turning then it's something with the front end. But check your 4wd fuses first. Thank you and enjoy the video. Disconnect the wires, and pull the actuator. Our switches are manufactured under a completely quality control process from componentry to finished products by experienced professional. Before that time, a pickup truck contained a hard, uncomfortable bench seat, a spartan dashboard with only the most basic instruments, and a three-speed manual transmission. Your Sierra 1500 always will be an excellent vehicle but over time even the best cars and trucks have to have replacement part maintenance or replacement of damaged components.
