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.
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.
i HAVE A 2003 FORD EXPLORER, WITH LESS THAN 15000 MILES THE REAR END STARTED WHINING FOUND OUT FORD HAD A BULLETIN ON IT , THEY REPLACED THE WHOLE REAREND.
Universal/U-joints are used to transfer power/torque from and engine to the drive-shafts and rear differentials. The U-joints allow the driveshaft and suspension to move thru it's normal range of motion, while still being able to transfer the power from the engine/transmission.
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.
buy a posi differential. it can be welded but it wont last long
Z28's came with a limited slip differential. Trans Ams had posi-traction.
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.
A posi rear end (positive traction) drives both rear wheels.a posi rear end is when both rear tires spin instead of just one
get a posi traction rear end and swap it out.
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.

If its a z28, then yes. The base models did not include the posi rear end
Posi was offered as an option.
