i was suppose to post this up long time ,this is for 4wd action.com. the article is about how to get your lsd to engage on the bt50,but i guess it would pertain to all vehicles that have lsd
Just a little thing that might help you getting that torque transfer thingy with Left Foot Braking to work for you. Get hold of a fairly tubular type jack, screw or hydraulic. With the vehicle in 2WD and on level ground, handbrake on, no chocks; very carefully jack one rear wheel just clear of the ground. Make sure that you keep clear of anywhere the car might roll if it comes off the jack, and certainly DO NOT get under it while it is raised, but try to locate the jack under the axle or suspension of the side you are raising - Driver's side is probly gonna be easier for what we are doing. Make sure that the jack is placed in such a way that when you drive off it, the jack won't stick bits into anything under the car, ie fuel tanks etc, and get the wheel just clear of the ground, it doesn't need to be 2" off the gound, just clear is OK, so the wheel will spin freely. Take the handle out of the jack too - stops it hitting anything.
Then get into the drivers seat, start the car, release the handbrake and gently release the clutch. Remember you should be in 2WD, and by releasing the clutch (or putting an auto into low gear) you should find the wheel that is raised spinning. If you are lucky enough to have an LSD that has sufficient pre-load to drive straight off the jack, stick a normal house brick in front of one of the front wheels! You can still improve the torque transfer with this left foot braking! Anyhow, now that the wheel is spinning, with your left foot gently on the brake and using your right foot to gently feed in power to keep the engine from stalling, gently increase the pressure on your left foot until the spinning wheel slows and eventually it should either drive you right off the jack, or at least you should feel it definitely trying! REMEMBER THE AMOUNT OF LEFT FOOT BRAKE PRESSURE YOU ARE USING to get it to drive off the jack!! That is effectively what you are doing on the hills etc.
That is how much left foot brake you are going to hafta apply to get any appreciable torque transfer when you are climbing or lifting wheels. And you might need a little more when the vehicle is in 4WD and you are lifting 2 wheels, 1 front and one back! We tried this in a BT-50 not that long ago - couple of weeks ish! And it helped make it easier to come to terms with the braking effort needed, it is probly more than you think!! AND it does help to get the car further than it could previously going!
While this technique will work for any vehicle with a diff, & especially those with LSD's; we have found that the BT-50 is as good if not marginally better than all the similar utes of this latest batch to hit the market, and the rear diff does allow torque transfer fairly readily, adding a fair bit to the rear drive especially. It will increase the ability of the vehicle to traverse ruts and humps where diagonal cross axle wheel spin is a problem, as well as helping you when climbing steep or loose hills - great in this latest lot of mud that has appeared 'cos of the rain!
Give driving off the jack a try, get the feel for the amount of brake needed, then practice transferring this braking effort into the real 4WD use! It is a good way to practice when you can't get out into the ruff stuff, and it's a good way to get on top of the skill when you are having problems. PRACTICE MAKES PERFECT!
hope this is helpfull and when alyuh going and test alyuh lsd . and v when yuh ready to sell check meh unless i bought one before you ready to sell
