    Transfer Box/Viscous Coupling - Grinding Noise & No Drive Greetings all Search has been done but I haven't found anything with similar symptoms other than transfer chain failure, H-L shift movement failure, or viscous coupling failure in which the coupling locks up - none of which seem to be...

    Was thinking of changing out the supercharger coupling on my 2013 with roughly 75K miles. Has anyone done this as preventative maintenance? Is it worth the cost or should I wait until I start hearing some noise?

    I'm replacing the viscous coupling in my 1995 RRC. I'm putting a new bearing and new seal in the VC housing. Do I need to grease the bearing before putting it in the housing, or does it just get lube from the ATF that goes into the transfer case? Thanks, Doug

    Anybody sugest the best place to get a new viscous as Ashcroft don't seem to have any at the moment.

    Hey guys, looking at the best solution to remedy my viscous coupling problem. I'm pretty sure the thing is seized. When I turn a circle in full lock, the rear inside wheel will roll then scrub as the windup is relieved. Also when I lift a front tire, it turns a bit when it leaves the ground...

    Had an intermittent overheating problem on my 1991 Highline. Some trips no trouble at all, but on other trips it overheated especially when traveling slowly in "town" conditions. The coolant was bubbling out of the header tank cap so the problem could have been an airlock problem and/or pressure...

    Hi guys My viscous fan has been running constantly since i bought the truck, so I guess it got stuck engaged. I bought a new coupling unit and after going insane do to the nut holding it in place I finally got it off :) I replaced the coupling with the new one and it still runs constantly at...

    Will a viscous coupling for the transer box on a P38 fit a Classic?

    My viscous coupling went bad in my blue 95 a while back and I've put off fixing it for a while now but I think I finally have time to tackle the project. I have never done a VC replacement before and there doesn't seem to be much in the shop manual about it. Does anyone know how to replace one...

    Looks like a flex coupling on my 94 SWB is in a very bad way. For some reason I can't seem to find the right part on Atlantic British or Rovers North? Would be great if I could get a little help. Thanks!

    I have raised 1 front wheel and could not rotate it. Gearbox was in neutral. Is it Viscous coupling unit, that doesn't work? :?::?:

    Hello fellow P38 enthusiasts! My 1999 Bosch P38 is suffering from a seizing VCU. I have been looking for a new replacement but seem to come up empty handed. Does anyone have a link or recommendation for a replacement VCU? Thanks in advance. -Oats

    Been noticing some issues. Vibration on turning, heavy steering, occasional chirp from front tires, and ABS triggering, and heavy tire wear on inside and outside of front tires.. Gets worse when hot or driven for a while. My diagnosis is pointing toward the viscous coupling in the TC is toast...

    Having read stacks of viscous coupling threads in the search section here are my results. I put the automatic transmission in neutral, applied the parking brake and jacked the passenger front wheel off the ground. With a torque wrench set to 60 ft lbs I was able to turn the wheel 90 degrees...

    I have the t-case housing loose and it is spinning several inches back and forth but I can't get the VC to release from its attachment point. The housing is only separating from the t-case by a tiny sliver and I can't really get anything (pry bar, screw driver, etc.) between the two areas to...

    What size is the output flange nut on the viscous coupling unit? My largest socket (1 1/8") is too small and I need to go buy a bigger one but I can't find in the WSM or on any postings that say what size it is. Does anyone recall what they used when tackling this project? Thx, John

    Hi I've removed the VC unit from the transfer box. I used a tri leg bearing puller to push the VC threaded shaft through the bearing and then pushed the bearing from the housing. Pretty straight forward but I'm wondering what's the best way to push the VC shaft back through the new bearing...

    Air suspension leaking at hose insert into valve block around coupling - help needed I replaced the piston seal and we're back up again but the rear sags pretty good overnight. I did a leak check and found that hoses #1 and #2 (rear springs) are leaking at the hose insertion point on the valve...
