It depends on the application. Posi is good for straight track racing, or good traction while off-roading, but wears out tires fast on curves and turns.
A posi was an option so unless it was ordered it will be an open differential, raise the back of the car off the ground, put in neutral and spin one rear wheel forward and if the other one spins also in the same direction at the same time it's a posi rearend.
GU6 is just in indicator of the differential ratio a gu6 is a 3.42:1 ratio. it could be single track, limited slip or gov lock. if it is gov lock you should also have a g80 code in your glove box. if so and you tow or have tall tires be ready to replace when master pin breaks
Yes, it will fit and mount up just fine. But you will have to make sure the front differential gear ratio matches that of your rear differential. Or what you could do is swap the transmission from the Forester along with the rear differential from the Forester
On the top of rear differential. Some vehicles have one at each front and rear wheel. Some vehicles have one at each front wheel and one on top of rear differential. Depends on the vehicle. The year, make and model info would help.
There are two U-Joints that are easily visible on a rear wheel drive vehicle. The driveshaft on a rear wheel drive vehicle has a U-joint at each end, just forward of the differential (the pumpkin-sized metal assembly on the rear axle) and near the transmission.
You buy a posi-trac rear differential.
buy a posi differential. it can be welded but it wont last long
The 3.73 rear end in a 1998 Chevy Silverado 1500 does not automatically mean it is a posi-traction (posi) differential. Posi-traction refers to a limited-slip differential that allows both rear wheels to spin together for improved traction. You would need to confirm with the specific vehicle's build options or VIN to determine if it has a posi rear end.
Yes it does. It's called a limited slip differential. Posi would refer to the Chevy brand rear end. No you don't have posi. Yes you have a LSD.
Z28's came with a limited slip differential. Trans Ams had posi-traction.
If it is a Posi then the friction plates are going bad.

sure grip
You can change the rear end of a 1988 Suzuki Samurai to Posi-trac by opening the differential and removing the existing ring and pinion gears. The Posi-trac assembly is then install and the gears put back in place.
the correct term is posi-traction which refers to the power to the differential then to the rear wheels, a posi-traction equipped vehicle provides power to both drive wheels if one of the wheels starts to slip, a non posi-traction vehicle only drives one rear wheel.
A posi rear end (positive traction) drives both rear wheels.a posi rear end is when both rear tires spin instead of just one
When I changed the fluid in mine it took 3 quarts to fill it up. Also if you have a posi-trac rear end you will need to put in a Posi additive. You can get it at Oreillys or AutoZone. If you don't put in the additive the rear end will make a clunking sound when turning.
