Ironpuppy, did this fix your binding problem?
 
Does anyone have the part # and/or price for the Viscous Coupler? I have tried to find it at my local dealership parts counter and we can't figure out which part it is on the expanded parts screen. I don't know if we're looking at the wrong page or what.

If the cost is to high then I am going to look at buying Slee's part time 4wd kit.

Thanks!

Have you called Cdan? He will know the part # I'm sure and will give you a better price than your local dealership. Just 02.
 
Yeah, it sure seems like it. I have been wondering if it was a problem, I just replaced my U-joints and with both DS's removed, tcase and trans in neutral, I could not rotate the output flanges in opposite directions. I also did the "one wheel off the ground test with both cases in N and DS's installed and could not rotate the tire, I do know that my front locker was unlocked for that test.

There is of course the other problem I am having, my CDL isn't working, I installed the switch, tested it and no locky (lights anyways), put it in 4lo, no locky. Hopefully (I think) it is something where the CDL is staying engaged and I can fix that, but everything I have read indicates that the CDL light would be on if it were stuck in lock. Although I can feel a difference when the CDL is engaged, the output won't rotate opposite each other at all, when the CDL is unlocked there is about 30 degrees or so of opposite direction rotation before the outputs stop turning.

Any other advice/checks?

Tortus,

If money is a big concern, don't forget that you can simply remove the VC and run indefinitely without it.

Thanks CJF, I was thinking that would be my next option, along with adding the part time kit.

Fortunatly/hopefully I won't have to deal with that! I just purchased a used (88k) trany and tcase today:bounce::bounce: for a good price! I am hoping the VC is good out of the Tcase and I will have the rest for spare parts :D Couldn't pass up the deal, so sometime next week I should know.
 
If anyone has yanked a failed VC, let me know. I could use one for a project...sooo don't throw it out drop me a PM or something and I will pay to have it shipped to me if someone is willing to put it in the mail.

Upsidedown has my failed VC in his shop. He was going to cut it open out of curiosity, but I don't know if he did. If you want it, it's yours. Just let me or Upsidedown know. Shipping from Canada, though... the VC assembly is about 40lbs.
 
BTW, MikePL thanks for the OP. Really well done.
 
I'm glad that you liked it, Iron :-)

rpfzj80, I also have a VC that I don't need but that's too far to send it. Surely someone near you will chime in. What's the project all about? Any attempts to repair a VC? From my understanding of the mechanics of a VC it seems that all the plates are bent and twisted from the heat inside and that causes a seizure. So probably there is no way to repair. But as soon as it gets warm here, I will go outside (no garage) with my cutter and post pics of the internals.
 
Hmmm, that might be a bit costly, but then again ground shipping has gotten cheaper. Does it really weigh 40 lbs...I know they're heavy but that seems high. If shipping was less than say 20 bucks or so, it would probably be worth it.

Anyone near CA have a trashed VC?

So let me get this right, because my feable brain sometimes has hard times with big words and numbers.

You can remove the VC without any change in the current drivability of the truck?

How is it off-road without the VC?

Mine turns but sometimes seems like it requires the force of hogan to get the wheel around. I think that just might be how a 10 year old power steering system just is....but then again I can be a hypochondriac sometimes.

Do the "one wheel off the ground" test mentioned (several times?) in this thread.
 
Sooo, anyone else have a trashed VC they would be willing to part with? Near to CA would be ideal...either way my dime for shipping.

Kind of resurrecting this thread as it appears I'm heading down this path. I don't have a binding issue, but have a lot of noise at highway speed from the transfer case. Put it up on a lift and put a set of ears on it and the transfer is howling at 45 and above. Both output bearings look good - no play, no seepage.

This sounds like the most cost effective "fix" for my pocketbook. Any other drawbacks and/or issues that have come up now that a few people of have done this?
 
Can VC be recharged, in other words, can the silicone fluid be replaced and rejuvenate the VC?
