MilesTolle Posted August 31, 2018 Share Posted August 31, 2018 I have noticed since I been driving my 1993 subaru legacy 2.2 automatic awd in the summer that when I turn sharply like into a parking space it feels like the back wheels are locked up it is fine in driving straight are backwards is this normal... I thought about putting in the fuse that turns it into a Front wheel drive for the summer time but not sure if that would cause problems if doing so... I have not tested it yet to see if it does it if putting in the fuse for front wheel drive are not though .... But anyways it is like wheels grab in the rear wheels when turning really sharp....

1 Lucky Texan Posted August 31, 2018 Share Posted August 31, 2018 does seem like torque bind. Try tight circles without, then with fuse in place. Let us know results. tell us about your tires, they must be identical - not just same size, same brand/model as well. Also, is the car new to you? could it have had a trans or rear diff replaced? 1 Quote Link to comment Share on other sites More sharing options...
heartless Posted September 1, 2018 Share Posted September 1, 2018 no, it is not normal. it is a symptom of torque bind the FWD fuse will not harm anything - put a fuse in and see if it helps. Quote Link to comment Share on other sites More sharing options...
moosens Posted September 1, 2018 Share Posted September 1, 2018 Have often driven in FWD in 80% of the year. Put the fuse in. Plenty of reading on Torque Bind out there. Quote Link to comment Share on other sites More sharing options...
MilesTolle Posted September 1, 2018 Author Share Posted September 1, 2018 (edited) I will put the fuse back and and test it for a while to see if it happens when switching it over to FWD... Then let you all know, here lately its been one thing after the other with this car. Edited September 1, 2018 by MilesTolle Quote Link to comment Share on other sites More sharing options...

MilesTolle Posted September 2, 2018 Author Share Posted September 2, 2018 I drove it to a church parking lot and went around in circles both ways and stopped and turned into parking spots on each side to see if torque binding happened. I did notice before I tested it that one rear tire was low on air pressure it showed it only had 15 lbs of pressure in it, while the other three had 40 lbs of pressure, would that cause torque binding if a tire was that low of air?

heartless Posted September 2, 2018 Share Posted September 2, 2018 possibly, yes Tires on these are a big factor. They all need to be within 1/4" circumference - preferably all the same brand, style, size and treadwear to prevent damage to the AWD system. Keeping air pressures regulated is also important. FWIW - if you have a flat and need to use the donut spare, you are supposed to put the donut spare on the back, and use the FWD fuse - that is what that fuse holder is for. Do Not use the donut spare on the front. Meaning if a front tire goes flat, you put the donut spare on a back axle, and move the good tire from back to front, use the FWD fuse and no damage will occur to the AWD system - this is the info you get in an owners manual. 1 Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 2, 2018 Share Posted September 2, 2018 40 is a little high for normal driving, check the manual or sticker on the door frame for proper values - but yes, if they all aren't the same 'rolling radius' you can have torque bind. If that was the issue, great. because some others ways that torque bind occurs require transmission work. Quote Link to comment Share on other sites More sharing options...
MilesTolle Posted September 3, 2018 Author Share Posted September 3, 2018 Thanks I guess I will no more as i drive it and thanks for the information heartless cause I did not know to do that in case of a flat and having to use a donut tire. And I hope that is all it was is low air pressure in one tire, time will tell. Quote Link to comment Share on other sites More sharing options...
MilesTolle Posted October 5, 2018 Author Share Posted October 5, 2018 I am late getting back to everyone, but been really busy, The torque binding still seems to be present in the rear it seems like the passenger side rear tire is like a stuck caliper when turning into a hard curve like a parking place are drive way when having to make that sharp cut into it. I have read where a Transmission Solenoid can cause this problem. It is suppose to be inside the casing behind the transmission pan at the rear of the transmission at the differential part of transmission. And could also be the clutch bands inside there as well I think you call them. Does anyone know for sure if a 1993 Subaru Legacy 2.2 sedan awd, automatic.. would have these in that casing before I go though all the trouble of trying to take that casing off, the job does not seem to hard to do, the pricing I am not sure yet.... The tires seems to be the same treading though, and same amount of air in each tire. So I am leaning in that direction once I find out for sure if this car has those in the casing part... thanks Quote Link to comment Share on other sites More sharing options...
Numbchux Posted October 5, 2018 Share Posted October 5, 2018 Yes, your car definitely has transfer clutches, which are controlled by a solenoid, usually called the Duty C solenoid. Does the FWD fuse change the symptoms? As I recall, the drum that the clutch plates ride in can get grooved or rusty, which can physically prevent the clutches from releasing. Otherwise the solenoid can stick, and sometimes the gasket that seals the solenoid to the case can leak, so fluid pressure is not held to the clutches. Typically best to just get everything. The dealership I worked at stocked it all, gasket for the case, solenoid, and gaskets for the solenoid (there's a spacer under it, and 2 gaskets, you'll have to replace both). If they have it in stock, they'll probably accept returns if you don't end up using it (make sure to ask first). As I recall the techs always asked for a little fluid tube back there, too. But the one time I did the job I didn't replace it, and I'm not 100% sure why they did (maybe someone else here will know). 1 Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 5, 2018 Share Posted October 5, 2018 If the FWD fuse makes a difference, the duty-c solenoid is good. Either the clutch pack is fried or it's sticky and the drum needs to be filed, etc. If it doesn't make a difference, the duty-c is failed.

MilesTolle Posted October 6, 2018 Author Share Posted October 6, 2018 does the drum that the clutch plates come as one item to purchase? It seems to do ok with the FWD fuse placed in it, but will do some more testing to make sure and get back with you all... Thanks Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted October 6, 2018 Share Posted October 6, 2018 how many miles on the trans? you might find a much lower miles entire trans from car-part.com or ???? to swap in. I THINK there is a certain year where some internal part was changed to a better alloy too??? Quote Link to comment Share on other sites More sharing options...

Thanks The drum is available from Subaru, but is probably prohibitively expensive to get that way. I know I've heard of people cleaning up grooves with a file with success. But if they're too bad, it probably makes more sense to get a used trans. But since the solenoid works, you've probably got a relatively simple repair. Gasket, fluid, clutch packs, some time with a file, and carry on. Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted October 8, 2018 Share Posted October 8, 2018 Does the car sort of slam into park? Do you have to give it gas to move the car while in reverse? The parts are not that expensive. Here is a link that will give you an idea. Quote Link to comment Share on other sites More sharing options...
