miscue Posted June 1, 2008 Share Posted June 1, 2008 Hey everybody I was hoping someone could take pity on me and post or point me to a picture of the vacuum lines I'm supposed to look at if my four wheel drive is no longer engaging? It's a 5 speed, push-button 4wd on a 1988 Subaru Leone wagon (New Zealand version of the GL, I believe). I've looked in the Chilton's manual and didn't see anything about how to troubleshoot it not going into 4WD anymore, even though it was engaging fine a few months ago. From looking at Beataru's recent thread here about being stuck in 4WD it seems vacuum lines might be the problem also for being stuck out of 4WD? But I'm an idiot about how to go about finding the right ones. My tires are the still the same as the last time it worked and I've tried to get it in on all types of grass, sand, rock, etc. Any help you could give is much appreciated.

Spiffy Posted June 1, 2008 Share Posted June 1, 2008 the thread you mention has a lot of good info it in... basically the white canister behind the strut tower (passenger/right side in the US) gets vacuum from the manifold and uses that to actuate the vacuum solenoids behind the other strut tower... the same white canister also works the vacuum actuated vent system inside the car... I had a problem with not being able to have defrost while going uphill because this system had a leak... so if all positions of the vents in the car work while going uphill then the canister is probably fine and the problem is in the 4wd actuator or the diaphragm it connects to near the transmission... --Spiffy Link to comment Share on other sites More sharing options...
miscue Posted June 2, 2008 Author Share Posted June 2, 2008 Thanks for the response. The problem was a rotten line at this plastic 3-way union. Link to comment Share on other sites More sharing options...
