Viscous coupling failure?
« on: January 31, 2021, 08:51:02 PM »
Hello, I just bought a museum kept 1981 limited wagon from a gentleman in Atkins Virginia who claimed to have hauled the car down from Ohio on a tow dolly. Is this a likely reason the car is slipping in 2 wheel drive? If there’s a post covering this I apologize but I’ve been reading for a few hours now and haven’t found anything relevant. Should the cars with viscous coupling be hauled on a flatbed?

Flatbed, definitely. They only way to use a tow dolly is to remove the driveshafts.

So this would explain why it’s slipping now in 2wd and working as it should in 4wd?

And if so, what needs to be done to correct the problem?

When you say slipping in it tries to move or doesn't move at all. Could be the actuator is not moving completely and is in false neutral on the transfer case. You can manually move the lever from under the car from one position to the other to insure it is not sticking in mid position.

It goes but there’s obvious slipping. When I try to pull a hill I hear it Erving but I have to put it in 4wd to get up the hill.

Hear any noise from the rear right side??   Could be the dreaded busted right axle (axle spinning in the hub).

Yes there was a noise coming from the rear sounded like a bearing going out. So a roaring type noise.

My first Eagle was an '81. It was full time, no switch. I bought it NEW off the dealer's lot, so I know it was factory!

They changed to "switch-able" 4WD part ways through the 1981 model year.
