Can VC be recharged, in other words, can the silicone fluid be replaced and rejuvenate the VC?

I seem to remember that it sealed. So, no.
And its like a $900 part. I am just going from memory though.

Is there any other car on the market with an open center diff???

- 91-92 cruiser is the only one I know

Nearly every 4x4 ever made has an open center diff. I'm not sure you understand how the diff works.

Another way to find out if your VC is dead is to raise one wheel (tranny in N, transfer case in N). In the N/N position the wheel should move rather freely when you rotate it by hand. If you lock the center differential the wheel should not move (it might have play but you definitely can't make turns).

My HDJ-80 has a LSD rear diff, Does the wheel should move freely no matter the LSD???

I'm looking forward to remove this VC thing today... I hate it:bang:
 
Riberware: If you have the Center Differential Lock switch you can remove the VC. Otherwise, if you loose traction to one of the axles it will just spin and no traction will go to the one with traction.

Is there any CONS with the removal of the VC and leaving the center diff open???

Ricky,
This is at least the 4th time in the past 2 days that you have asked this question. You have been given answers each time. You have been given Toyota documents that describe the function and purpose of the Viscous Coupler (VC) in your transfer case.

What more are you looking for? Do you want someone to say, 'Sure Ricky, just pull it out and drive it?'

If that is what you want then.... "Sure Ricky, just pull out the VC and drive it."

-B-

Sorry for being an arse hole...

I did the cirgury today, took me 45 minutes, now my cruiser is so smooth!!!!!

And yes now I do have a litle clunk... but I think it's normal...

Doc, you know better than that...

OK, my 4WD experience has been limited to jeeps with center diffs. Sorry. I was also thinking about the suby's with center diffs.
There's lots of vehicles with center diffs. I guess maybe not a majority though... I got a bit carried away with that statement.

You know, all of the '4WD' vehicles I've ever owned have had one though.... 2 jeeps, and a mitsubishi. I guess that's not a very big sampling though, 'eh?
 
Other problem

Now I deleted the VC, ABS and CDL are working great... I was using the car all day, everything fine and I was very very happy with my cruiser today... but like 7 hours later after the cirgury I started to hear a loud and intermitent groaning soung coming from the front end... when I accelerate the sound stops for a while....when I completely stop the car and accelarete the sound dissapears for a while too.

I'm 100% sure it comes from the front end... maybe the spindle bushing is dry, I changed both a week ago, maybe a bearing or a problem with the ABS.... who knows? I'm trying not to loose my patience.

I just hope this new problem got nothing to do with the removal of that darn VC.

I'm starting to hate second hand cruisers. PO sucks!!!!!!

:confused: a Jeep?.....with a what? :confused:

You do know that just any transfer case IS NOT a center diff, right? :confused::confused:


No, its us that is now sorry, sorry.



THIS is the kinda s*** that is killing some of you.

Some new TC's are marketed as AWD or a slight misconception of a misnomer......ALL TRAC!...sport trac, tick tack!...tallywack!

Ultimately they are PT TCs and share the same architecture. WHAT gives them the Bull SHat traction is the activation, most have wheel speed sensors (on all 4 :doh:) and in the instant wheel slippage + or - is detected it basically engages 4WD.


I cant keep doing this I'm burnt out..........


Can someone upload the New Venture/ New Process product line?:rolleyes:

If you had a seized VC then probably your front end is toast. While making turns with a seized VC the rear wheels lock and eventually let go, relieving the tension, but the front of the truck is heavy
(due to the engine) and the wheels are less likely to slip. This puts a lot of tension on the front differential and birfs. They are literally twisted.

the loud groaning noise was a dry spindle bushing, not enough grease... fixed that today....



BTW this is my VC (thanks for the tutorial!!!:popcorn:):
