Default Cost to fix the torque bind problem on a 98 GT

For the past 1.5 years, my wife's 98 Legacy GT wagon has exhibited the infamous "torque bind" problem. It's never gotten worse. When we bought the car used from Subaru it had this problem and I demanded they fix it before I bought the car. They fixed it, but a year later it was back. I've measured the tire diameters and they're perfect. When I put the FWD fuse in, the problem disappears so it's definitely the torque bind problem. The only time the problem appears is when the car is making tight slow speed turns. The car feels a little jerky even though the throttle input is steady.

Has anyone gotten this problem fixed at Subaru and how much does it cost? My wife doesn't care, but it annoys me when I drive the car. Over 2.5 years of ownership, this will be the first item we have to fix on this car.

BTW, are Legacy GTs normally fairly rough riding cars with a good bit of road noise? The car soaks up big bumps quite nicely, but overall the road noise and general "graininess" is apparant during most driving. In the warmer months the car rides a bit better because suspension/tires loosen up a bit. I'm just wondering if this is normal or if the tires are the problem.

My dealer adds a can of something everytime mine gets bad - cost is under $20 and it lasts about 8 months on my 91.

I think it is a friction additive or something - Subaru specific.

And then he does a bunch of figure 8's in the parking lot.

Oh, and tires are the biggest noise makers in Legacys - well, after the mirrors...

I *think* I recall Huffer had a similar problem and he fixed it by using a product called "Lube Gard". I think it took a few hundred miles of driving before the problem was "fixed". I am not sure if it was a temporary fix or a permanent one though.

Here is a link to the product being sold on Amazon :

http://www.amazon.com/Lubegard-Automatic-Transmission-Protectant-Perfomance/dp/B000F2JZ68
Just to reiterate this product can be used for fixing torque bind on AWD Subarus with Automatic transmissions. Its not for folks with manual transmissions.

the viscous coupling in the center diff is sealed, and is likely the cause of the binding. Adding something to the transmission isn't going to help anything. swapping the diff takes a couple hours and most and doesn't require the transmission to be removed. You can get a used one in good working condition for about $150.


edit- this applies to 5-speeds.

Mopar LSD additive is what my mechanic (who worked in a dealership for 8 years) recommended

What you mean is that I would add this to the fluid already in my rear diff?

Yup, thats it, and it ended up being a permanent fix on all Subbies I've used it on. 2 of the 3 of them are still cruising along without any issues. The 3rd I actually parted out and it went to the junkyard. But it never had torque bind again for the 30k I owned it.

It's not the rear diff that's the problem. It's the trans.

The kit says flush and additive, did you flush your transmission? If I cannot find lubegard on Guam can I use sea Foam?

Seafoam isn't an additive, it's a carbon dissolver/cleaner. It's used to clean carbon deposits and oil sludge. If you put that in your tranny and leave it in there, it'll eventually break down all your gear oil! Just imagine what that would do to the internal components!

And just for reference, I know of a guy who put seafoam in his engine oil and left it in there (he was trying to clean out the oil sludge in his motor). About a month or two later, he was forced to shop for a new motor, if you take my meaning.

I got most of everything fixed on the Legacy except for the torque bind. I am still waiting on the Lubegard I ordered.

Could not find dexron II so I bought dexron III and added a bottle of Lube Guard friction modifier. I just drained and did not replace the filter added about 3 qts + lube guard. Drove it around the block and the bind is gone it does not make that sound anymore maybe after a few miles on it it will be completely gone.

And there you go.

Check back in with us in about 100 miles, but I'm confident that you're number 16 that I've suggested LubeGard to that has fixed the problem.

It is okay I just noticed that on u-turns it feels that it is still binding. I guess this is just the way it is. I have driven about 15 miles so far.
