    Bad viscous coupler, disconnecting front shaft

    My 92 previa's viscous coupler bit the dust. I have no use foe the awd and certainly dont want to pay the big bucks to fix it. After doing a lot of online research and struggling through conflicting reports I thought I would give it a try myself. Thought someone may benefit from my experience. First I simply took off the front shaft. The van seemed to drive fine but when I would put it in park, it could still (somewhat reluctantly) roll. Not wanting to rely on my parking brake for safety reasons (no, not having the van roll over the neighbor kid, I mean not having the brake lever impale me in the butt every time I get out of the van (dumbest design on the Previa!)), I decided to try locking the fork shaft. There is another threat here with pictures of the service manual showing how to do that, but it was really easy. Remove the locking pin that can be found facing straight down through a hole on the sheet metal protective covering of the transfer case, then remove the cover for the fork shaft ( it is I think a 17mm nut/cap facing the back of the van on the back side of the transfer case, then pushing the shaft .59 inches towards the front of the van and replacing the pin and cover. I had a little trouble at first getting the locking pin back in, but then I wiggled the yoke that once had my front shaft attached and it went right in. Everything is working great now. I'll try to remember to check back in and let you know if it continues to work fine, but another fellow here got 12000 and going miles on his that he did the same on.
