i'm fairly new to this, and as there are alot of discussions about lockers, i find myself trying to figure out what they are. i only have a vague idea of their purpose, and was wondering if somebody can explain it or point me to a website that will. also, who needs them? thanx.
that was very helpful, thank you. but that raises a few questions...it said that some 4wd are manufactured with open differentials. so if only some are manufactured with open, then what do the others have? and how do i tell what kind i have? thanx.
The most common optional diff is a limited slip, but GM offered the Gov-Loc torque-biasing diff in some years. They now offer the Eaton E-Locker selectable locker in the H2.
Some of the others offer a clutch style limited slip in the rear as an option. Most are notoriously weak in action. I'm not aware of anyone still offering a factory front limited slip differential.
Other brands have made the jump in offering selectable locking differentials. Some are cable operated, some are electric. Some offer both front and rear. They include:
Various Land Rover models
Mid 90's up Toyota Land Cruiser
Toyota Tacoma pickups- specifically the TRD option package, but they could be ordered on a standard pickup as well.
Most recently, the Jeep Wrangler Rubicon with front and rear lockers.
To tell what your truck has, the best way is to pull the diff cover and take a look. The easiest is to look for the differential tag on the cover.
The only locking diff on a recent (~90-up) Land Rover that I've heard of is the center diff in the t-case. That's all that I've heard the LR technicians I off-road with talk about. Since 4WABS w/Traction Control & Hill Descent are becoming standard, I think they're even dumping that one.
They even have an electronic sway-bar disconnect system!
