bakatono Posted December 29, 2015 Share Posted December 29, 2015 Hey all, first post, long time reader. I am based in Japan and own a legacy 2.0r GT auto used with 80,000kms (50,000miles?) After a play in the snow yesterday i noticed the front wheels don't seem to be receiving power Here it is on youtube: The fronts don't seem to spin at all on throttle, or off throttle. I'm not sure about the left front, haven't seen it yet. What type of AWD system is in this version of legacy? Any thoughts? Link to comment Share on other sites More sharing options...
bluesuby Posted December 29, 2015 Share Posted December 29, 2015 Look at the owners manual. I recall there is a fuse which can be removed to disable the all wheel drive for towing, but only on cars with automatic transmissions. Link to comment Share on other sites More sharing options...
whitetiger Posted December 29, 2015 Share Posted December 29, 2015 ^no. lets learn how the center diff transfers torque. its not a locking diff, but rather a biased planetary with clutch activation. it cannot send 100% tq to the front if the rear wheels spin, but rather bias tq to the front to get the car moving. that why the car went forward instead of just spinning the rear wheels with little forward movement. this is normal operation.

c-lo Posted December 29, 2015 Share Posted December 29, 2015 and look at your video again. Your front wheels are spinning, just not as quickly as the rear. 258k miles - Stock engine/minor suspension upgrades/original shocks/rear struts replaced at 222k/4 passenger side wheel bearings/3 clutches/1 radiator/3 turbos Link to comment Share on other sites More sharing options...
bakatono Posted December 30, 2015 Author Share Posted December 30, 2015 thanks for the replies! very informative i played with the fuse to see if much changes, and with the FWD fuse inserted, i don't get any AWD light coming up on the dash. it doesnt seem to send power only to the front either. After doing some tests on grass (which has more traction than ice ha) i can confirm all wheels are receiving power, quite a lot actually. I read the original spec for the car in Japanese and i'm led to believe this model has an LSD of sorts in the rear and the centre? therefore if the front diff is an open diff, I'm wondering if most of the power has gone to the wheel with no traction sorry for the false alarm!

It's possible that in your video, the left front wheel is spinning, and both rear wheels are. To test my awd and rear LSD, I found some wet leaves, and let the clutch out quickly from a stop, then put the clutch back in after a foot or two (was in my driveway). It showed both rears spun, and one of the fronts. As expected for a car with a rear LSD and an open front diff. Link to comment Share on other sites More sharing options...

mrmako Posted December 30, 2015 Share Posted December 30, 2015 You most definitely have an AWD car. Link to comment Share on other sites More sharing options...
