question about my cousins POS( non RBV)

[Kdawg532]

my cousin bought this POS 89 Corolla all-trac and i was wondering how the drive train was, there is a button that says lock center differential and i was wondering if that meant it was then 4WD or if while the button was unpushed it split the torque up, um i am tired so i dont feel like looking at the moment i was just wondering if anyone knew anything about it or not

Dunno. Jack up the back, play with the switch and see what it does.

Sounds like it has AWD *AND* a locking differential. Nice.

One form of (simple) AWD has an open center differential between front and rear. You can use this when traction is good.

You can lock the differential when it is slippery out and you think you might get stuck (or you are stuck). Do NOT do this on good traction or you'll break stuff.

sweet, thanks for the info, i wasnt to sure about that stuff. i have never owned a 4x4 or an AWD so i know nothing about them.

I'm almost certain it's an all-wheel-drive with a center lock. I'll clarify what that means.

An all-wheel-drive means power goes equally to all four wheels as long as they are all sitting on traction. There are 3 differential--one per axle and a center one. As you know, the power follows the path of least resistance in a differential. If one out of 4 wheels slips, all of the power is going to go to that wheel. You can be stuck with an AWD just like you can be stuck in a 2wd--with one tire on a patch of ice and the other 3 on dry land. The center lock locks the center differential and turns it into a part-time 4x4 system. Now the power will follow the path of least resistance but it's split into 2 seperate parts. The front axle doesn't affect the rear. If only one tire is on ice, no problem--the other axle has 2 tires on dry land. If one tire from each axle is on ice--THEN you can still be stuck with one tire on each axle buzzing helplessly on the ice. It's common to get stuck by sliding off the road into a little ditch and haing the 2 high-side tries unloaded enough to spin and go nowhere. That's when you wish you had an axle lock instead of just a center diff lock.

that would piss me off to no end.......

Yeah, but you're locked and loaded. You could just slap leather and blow some chunks off the stupid machine and walk home satisfied at a job well done.
