Thanks for the replays guys. I have the plate with the info for the engine and gearbox under the hood,but how to check the number on the gearbox without to remove it from the car and how to understand did my rear dif is changed or not?

Sorry i forgot to say..all 4 tyres are the same.

Hi to all subi fans First of all my english is not very good so,sorry for my mistakes So,i recently buy Subi Legacy IV Gen Wagon 2005 , 2.5 165hp 4EAT. I change everyting that necessary in the engine room and the transmision + ATF and front and rear difs oil.They told me that the old rear dif oil was black.Everyting looks great but i have some issues with some kind of torque bind maybe. When i go out from my garage in reverse and the garage is on the gravel uphill road,so when i back up the rear tyres start to bind but only my steering wheel is more than 90 degree turn.In the clear ashphault when i back up with steering wheel turn far left or far right dont have the binding issue.I buy the car with the switch next to gear lever that is replace the need of put the FWD fuse everytime.The wires are cut under the fuse hole and wired to the switch.One white wire goes from the switch to the group of wires that goes to the socket of the button that command the electrical mirrors.I think its goes to ground or 12v ( the last picture). So,when i push the switch in ON position the AWD light apears in the dash. But the bind continue and i think the rear wheels still works,because i lift up the whole car and when i turn on the switch and put in D or R the rear wheels still spins.Is the duty C dont working propoerly ? and if my duty c dont work properly is that mean that my subi dont distrubute the power normaly like 50/50 in first and reverse and 90/10 in normal conditions and now atm with bind problem and maybe not working duty C my subi is locked 50/50 all the time?
