One new and one wore tire can destroy the posi Trac.
most commonly the right side tire is the traction tire unless it is a posi-trac rear end. then both tires are main traction tires. the easiest way to tell is lift one tire off the ground leave the vehicle in neutral and if the tire rotates there is not a posi.
Check under the back seat or a compartment in the rear of the suburban.
More than likely it does, to check, jack the back of the car up and put the car in neutral and spin a rear tire by hand and if both wheels spin in the same direction you have a posi.
Raise the rear tires off ground. Spin 1 tire while watching other rear wheel, if both rear wheels spin in the same direction it is a posi-trac rear.
"There are two options that were installed. One and most likely yours, a 3.27 non locking diff (not posi) and the other was a 3.55 with locking diff (posi). Easy way to tell. Punch it if one tire spins it the 3.27 and if both spin it's the 3.55." That's not really true. The 3.27 was available in both posi and open diff. Nearly all P71 models have the posi unit, and a huge majority of them have the 3.27. Best way to test whether it's posi.... jack the rear end up and put the tranny in neutral. Spin one tire. If the opposite tire spins in the same direction, it's posi. If it spins in the opposite, it's open. 3.27 vs 3.55 would just be a matter of calculating engine RPM vs road speed.
How do you change a tire on a 2000 chevy suburban
I differential works when opisite tires on an axle turn at different rates (ie. turning a corner the outside tire turns faster then the inside tire). a posi rear end locks up when one tire increases speed suddenly while to other is stationary or turning very slow. If your tires are different sizes from side to side then the differential gears ( spider gears) are turning all the time and will burn up as they are not desined to turn all the time and at high speeds. If you have smaller times then the diff wil lock up sooner and if they are much larger then factory it may not lock up soon enough.
I can not swear to it on your 95 but on my 94 suburban the jack is on the drivers side under the cupholder on the rear wheel well in front of the spare tire. hope this helps.
Nothing, if she as at fault she is responsible to the damages of her car.
may be on frame rail pass. side front of rear tire inboard of frame
jack up drive axle with vehicle in neutral and turn one tire. If the tire on opposite side turns the same direction as the one you did you have posi traction. If it turns the other direction its a diff.
Removing a spare tire is easy to do from a Chevy Suburban. The tire is removed with the tool that is located on with your jack.
