rottenhead Posted October 3, 2004 Share Posted October 3, 2004 '92 Legacy wagon AWD AT, 230K I've had bad binding when parking and turning at slow speeds for awhile now. Searched the forum and decided to give the FWD fuse a shot...and the problem completely disappeared i.e. it drives like it's never had a problem at all. I realize I can't/shouldn't leave the fuse in. I'm just wondering if the fact that the binding disappears with the fuse in narrows down the problem at all or if it could still be a number of things. Mucho thanks--rotten Quote Link to comment Share on other sites More sharing options...
wrxsubaru Posted October 3, 2004 Share Posted October 3, 2004 The FWD fuse will make it so your cars only FWD so you shouldent have binding. I thought you could leave the fuse in with out any side affects to longevity? Quote Link to comment Share on other sites More sharing options...

cookie Posted October 4, 2004 Share Posted October 4, 2004 the least expensive would be tires with slightly different sizes. The painful bit would be internal tanny problems. Quote Link to comment Share on other sites More sharing options...
rottenhead Posted October 4, 2004 Author Share Posted October 4, 2004 the least expensive would be tires with slightly different sizes. The painful bit would be internal tanny problems. Either way though, all it essentially indicates is that the problem isn't originating in the front end, correct? It's tempting to just leave the fuse in b/c it really drives like crap in AWD. Esp. if Im eventually going to have to replace the problematic part anyway. On the other hand, if I'm trashing a part that doesn't need replacing and/or risking safety...

rottenhead Posted October 4, 2004 Author Share Posted October 4, 2004 search torque bind and youll know exaclty what is wrong with your car:banghead: . and no, its not a good thing I have been trying to figure it out with the torque bind search but it's been tough to narrow it down. Many of the threads indicate different causes and solutions (e.g. tires, duty solenoid, clutch packs, electric and fluid flushes, wire tests or complete replacement). It seems like the problem has baffled or at least confused most mechanics/dealers from what I can gather. I definitely have all the same symptoms of others, and I apologize for taking up more space with a common issue. It just really surprised me that the symptoms were eliminated with the FWD fuse, although I guess it shouldn't have. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted October 4, 2004 Share Posted October 4, 2004 change the tranny fluid first......see if it gets better. Quote Link to comment Share on other sites More sharing options...
charlierh2 Posted October 4, 2004 Share Posted October 4, 2004 for minor cases i believe i read that a full tranny fluid flush and slow figure 8's in reverse could help to fix it.... but not sure if that was exactly it. but whatever i read i got it from this board.

wrxsubaru Posted October 4, 2004 Share Posted October 4, 2004 Ive read that keeping the FWD fuse in, is ok as long as the front and rear wheels operated with noraml speed difrences. e\Example its ok to drive around town but not ok to drive on a 2 wheel drive dyno becasue teh extreme speed difrence in the center will cause it to burn up.

NOMAD327 Posted October 4, 2004 Share Posted October 4, 2004 If putting the fuse in makes a difference, that proves the internal solenoid is able to work. The duty solenoid as it's referred, is normally cycled by the transmission computer to regulate torque distribution front to back. If it's on all the time, as with the fuse in, It's FWD only, and the coil windings are now subject to more wear. Torque bind is most simply caused by different diameter tires front to rear as has already been stated. If that's not the cause, the other remedies discussed may help, but it's probably something more complicated than that. Quote Link to comment Share on other sites More sharing options...
blitz Posted October 4, 2004 Share Posted October 4, 2004 Nomad, the coil windings aren't really subject to any wear. Rather the issue in question has been whether the coil will overheat if it is continuously on, and I've concluded that it won't. It could be reasonably assumed that the coil's temperature-rise would stabilize at the end of 10 minute continuous-on condition. So if it's acceptable to drive around for a day with the fuse in, then a week, a month, or indefinately wouldn't be any worse. Quote Link to comment Share on other sites More sharing options...

I've almost settled on just leaving it in...at least until the first snow. Driving with torque bind feels like I'm destroying the car. I'm going to do the transmission flush and my snows, which are all identical in wear, are going on in a month. I'm inclined to think it isn't differences in tire size b/c I had the binding issue over the winter with my snow tires on as well. Quote Link to comment Share on other sites More sharing options...
