Re: Rear Axel pull on '01
That was kind of hard to understand... S Texas.
I think what your asking is: does my truck have an open differential? A limited slip? Or a Locking differential?
Your truck MAY have a limited slip (option), most likely is open. Not a locking differential.
Open: Wheel with Least traction gets the power
Limited Slip: Wheel with least traction gets Most of the power (varies with clutch packs/ springs)
Locker: Both wheels completely locked 50/50 torque split.
For on road driving, and "most" of us, a limited slip is enough to help out on putting the power to the ground. That being said, I run a locker in both ends of my Jeep, and in my 2wd Ranger I welded the rear spider gears to each other to "lock" the rear end. I do NOT recommend this, This will mean I'm screwed if I ever need to pull them out for any reason (i'm ok with that, it's a $30 axle lol).
Cheap way to get a locker? IF you have an open carrier you can get an "insert" lunch-box locker that fits inside the stock open carrier for $200-$400, and you can do it yourself in the driveway in half an hr. If you have a limited slip your looking at buying a new whole carrier to get an actual locker, meaning $500-$1000+ pro install ($varies $200-$400)
