are diffs locked when in high or low range

A Land Rover Discovery was the vehicle featured in the demonstrations, but this video applies to any 4x4 vehicle with a center diff lock. In summary, diff lock (whether it be the centre diff lock fitted as standard or front/rear aftermarket diff lock) is useful in slippery situations such as snow, ice and mud.n summary, diff lock (whether it be the centre diff lock fitted as standard or front/rear aftermarket diff lock) is useful in slippery situations such as snow, ice and mud. The default for action for 1998 and 1999 model 100 series vehicles is when you shift the transfer case to the Low range the center diff locker is automaticly engaged whether you want it that way or not. The pin-7 mod disables the automatic engagement so you can choose to have an open center diff in the Low range.Giving you full control to use Low range on surfaces with high traction without drivetrain windup. This behavior is already incorporated into 2000 model year and beyond 100 series.he pin-7 mod disables the automatic engagement so you can choose to have an open center diff in the Low range.

Use exactly the same procedure to change either out of locked to standard low range (don't use difflock when not required) or when going back up into high range. you'll soon get used to what gear ratio's are like in low, but basically, 3rd low is similar to 1st high.irst of all, I assume I'm correct when I say engaging the diff lock simply locks the centre diff, thereby meaning that I will always have at least 1 wheel spinning on each axle. Please try again later. This video instructs the viewer on how the standard *CENTRE* diff lock works in a permanent 4 wheel drive (4x4) vehicle, a Land Rover in this case, and gives an idea for how and when to use it.n summary, diff lock (whether it be the centre diff lock fitted as standard or front/rear aftermarket diff lock) is useful in slippery situations such as snow, ice and mud. If your Range Rover does not have a diff lock knob/lever, you are unsure whether it does, you think you might have a limited slip centre diff or you have axle diff locks then method c) is the only one you can use easily.a) Disengage the diff lock. Chock the rear wheels. Put the transfer gearbox in Neutral.f your Range Rover does not have a diff lock knob/lever, you are unsure whether it does, you think you might have a limited slip centre diff or you have axle diff locks then method c) is the only one you can use easily. In most cases the problem is that corrosion has built up on the linkage itself causing metal to lock up into one very solid piece. This may effect your low range/high range as well, but it doesn t have to. Your low and high range function of the lever can work fine while the diff lock function remains stuck.ow a 13mm socket to the top of the transfer case and with a small amount of force and only a little turn you should be able to engage and disengage the diff lock. You can have someone sitting inside with car in the on position to see if the diff lock light on the dash turns on and off as you move the socket. Four-wheel drive vehicles have a transfer case, not a differential, between the front and rear axles, meaning that the front and rear drive shafts will be locked together when engaged. This provides maximum torque transfer to the axle with the most traction, but can cause binding in high traction turning situations.owever, not all four-wheel drive vehicles are all-wheel drive, as vehicles with more than two axles may also be described as four-wheel drive regardless of how many axles, so long as two axles (of two wheel ends apiece) are powered. A couple of things, if I may... Here are the positions I can put my diff lock lever into (as I'm sure you are all aware)! 1 2. N 3 4.
