I don’t want to provide you with any terrible news, but it Appears similar to what I just went as a result of… and it absolutely was the Transfer Scenario that needed assistance… poorly. My Blazer likely only has 10-fifteen hours to the 4WD technique, yet the “forks†Within the TC were being badly worn and making it possible for my gears to drift, which developed signs or symptoms like you describe (among Some others).
Also needed is string or fishing line and accurate steel rulers in addition to safe stands to attach the string at wheel hub peak. The stands I applied were being a set of jackstands.
The first thing I might do is disconnect the battery and Enable it sit to get a 1/2 hour or so — then reconnect the battery and cycle the ignition from on to off three times — this should reset the TCCM.
Yep, you both Use a terrible TCCM, negative encoder motor, broken vacuum strains, lousy actuator or a dilemma along with your transfer scenario — all of which has been covered in this thread.

This is a frequent mistake made when people have a “change on-the-fly†variety system.
Exceptional — I’m happy that my blog was ready to help you clear up your issue, and ideally help save some cash! Regards;
With a fixed gear, you don't have any these kinds of option. For those who capture a shoelace, it will get torn off or your shoe. When you capture a trouser leg, you can definitely get damage.
Maintain your eyes on eBay — I just noticed 1 Choose $a hundred thirty five that a man bought completely new 6 months in the past and is also scrapping the truck. You can find them with the Chevy vendor, but they are appropriate around the $500 mark — ouch!
If by unplugging the TCCM you hope to which the automobile will default to 2WD — it won’t. Providing it’s essentially Doing the job and driving your axle(s), depart it be and obtain it to a mechanic ASAP.
As to your problem — I have found that at the same time — never to the intense you condition, but I've noticed that the Blazer operates amazing when at idle and/or lower speeds — about the freeway you’re melting your eyebrows!
