And a large amount of brake dust can cause it too. There's about 100 pages on the 246 in my manual. I simply pressed the buttons while watching the scan data. The tires are all the same dia. The contact did not cite any performance issues with the vehicle. The dealer stated it was normal play in the drivetrain. I drained the transfer case fluid and found three little pins attached to the magnetic drain plug.
The failure mileage was 131,000. Actually that may or may not be correct. But, it's pretty involved to do the troubleshooting and you may not have the tools or inclination. Remove the oil filter and make sure the old gasket comes off. We replaced that and the different lights would light up when pushed, but we could not hear anything at the transfer case to indicate anything was happening. As soon as I got home I called my mechanic, he said he had worked on several 2000 silverados with this same problem lately. Before that, pull the ground wire and clean the frame off where it connects underneath the drivers door.
Tom, Take me thru what happened exactly again? The 4 wheel drive light stays illuminated and there was a leak coming from the drivers door. The contact inspected the vehicle and noticed that the transfer case was fractured around transfer case housing. A axel seal that is leaking gear oil into the drums. The brake control resistance was in spec but when power was applied, it would not allow the motor to spin and change modes, it stayed locked. The vehicle was not diagnosed or repaired. I have been driving around without 4wd ever since. Thanks for all of your help.
It seems logical to use case studies to show how these systems can be repaired. During this time I was taking my daughters friend home and was in a really tough spot against the side of a very big hill and realized I had no 4wd. While the contact's son was driving approximately 30 mph, the vehicle lost power and vibrated. I was going to put some jb weld on the hole for the time being. Was towed and part replaced. Complaint Number: 10020216 Date Added to File: May 20, 2003 Description of the Complaint: The vehicle automatically shifted into 4-wheel drive.
I'll see if I can come up with a way to get you the manual section. Getting back to the transfer case, you said you worked on them? It's chain driven from crank sprocket to cam sprocket. The transfer case module sends 8 volts to the switches, then monitors the return circuit to determine whether any of the switches is depressed. They also are rated for putting 500 pounds of downward pressure on the trailer tongue. The only culprit left was the wiring harness between the fuse and front axle motor.
That will save… Chev 350 thermostats are under the housing where the upper radiator hose connects to the block. Soulution is an expensive overhaul of the front transfer case. Sorry about the 'personal experience' question. That's where the thermostats at. My fix was to lower the brake control spring tension, I cut off half a turn from the spring.
It takes about two hands to rotate it when it's in 2wd due to clutchpack drag. When I shifted back to park there was a brief grinding noise. When I touched the hole with my finger I noticed that the transfer case had really weak medal in that area like when it was made it was not made right. If not, what other diagnostics should I try? Since the pump was not working it burned the clutches up. I saw this on Instagram for anybody wanting to do something like this.
The teeth on the lever that engages the 4wd? There's about 100 pages on the 246 in my manual. So finally have everything off of my truck and pics of everything. My nephew is a mechanic at an independent service garage and he borrowed the super duper snap on code reader. Posts I have researched say to place transfer case in neutral, this is position new motors are shipped in. When replacing the thermostat and housing make sure you thoroughly clean both surfaces and use a small amount of gasket sealer Answerfollow the top radiator hose to the top front of the egine. When I was stopped the vehicle put itself into 4wd low without me knowing.
I have been building a garage and put most of my tools in a storage building. But cars with an automatic transmission have no clutch that disconnects the transmission from the engine. I actually got stuck on the hill while the rear wheels were spinning out aggressively in the snow. My transfer case came in this morning and should be installed by tomorrow evening. All four wheels had to be replaced at 6000 miles because they were rusted. Those units have a clutch pack that wears out esp. In all cases, turning off the vehicle and restarting seems to return to normal until it happens again.
