Keep the eyes on eBay — I just noticed 1 go for $one hundred thirty five that a guy purchased brand-new six months ago and is scrapping the truck. You can find them in the Chevy seller, but They can be ideal around the $five hundred mark — ouch!
It stumped my mechanics for quite a while — every thing else was checked (they even purchased up sections with the front diff, and afterwards sent them back again) and all of it looked superior. The transfer circumstance was The very last thing they checked out (don’t ask me why — I assume the symptoms don’t issue to it).
Could you tell me what my dilemma is and if it is a straightforward repair service? I listen to no sound whilst I'm pushing the button, just the lights blink and then return to 2hi. Can any one support me?
I didn’t know I'd lost the links into the schematics likewise throughout the conversion. What I've, I have added again on the report at the best of the site. I hope this allows!
What it appears like is you may have an encoder motor trouble — This can be the motor to the facet in the Transfer Scenario that controls the shifting of the assorted “modes†(2Hi, 4Hi & 4Lo).
Yep, you possibly Have a very undesirable TCCM, undesirable encoder motor, broken vacuum lines, terrible actuator or a challenge along with your transfer case — all of that has been coated within just this thread.
The opposite place for 4WD vacuum is underneath the battery — but that is very a distance from the motorists door, While something is achievable.
Many thanks for that update — that’s what we want to listen to! I’m glad to have already been ready to assist maintain a number of of People greenbacks inside your wallet — Specially at Christmas! Best Regards;
I hope this data assists anybody with a similar trouble. Also i have breakdowns of almost everything on these cars Be at liberty to electronic mail me for another thing I really like your sight and imagine information like This could be shared to any one.
I’m not sure why you'd probably wish to pull the cable within the front diff — I assumed you reported the front axle turns when in 4WD but not 2WD? If that's the situation, the axle is engaged (meaning the cable is remaining pulled).
The vacuum change shouldn’t make A lot sounds, not plenty of to get confused with one thing operating. What I think is you will be Listening to the encoder motor within the transfer circumstance endeavoring to shift it into 4wd.
so i just spent 7 hours on my again yesterday transforming the transfer scenario just to discover that it is suppsed to become like that. i am outside of my intellect rigth now and that must be one of many worst mechanically concerned Employment i have at any time been involved with.
It only took a couple of minutes to Track down the module and the issue was Obviously visible soon after eliminating the module with the frame to possess a closer glance. The wires/plug connector had been terribly corroded on a number of pins — which led to two damaged wires (pin #one, grey w/ black and pin #6, orange).
PS – the “encoder motor†will be the element that “holds†your TC in the varied modes (well, that’s not browse a hundred% precise both — the encoder motor shifts from one manner to another — parts In the TC really “hold†you in that method — in my scenario, it had been a set of “forks†with plastic bushings that wore out — which does not sound like your dilemma).
