I have a 97 disco. I just wanted to know when to use the diff lock gearing that came with my truck. What type of situation do I use the Regular Low, Diff lock Hi and Diff lock Low?

 

Unlocked Hi is normal everyday driving.
Locked Hi is for bad snow covered roads, pulling your boat out of the water.
Unlocked low is for low speed deep snow, light off roading, wet grassy fields.
Low locked is for pulling a house off it foundation, serious off roading, deep sand, mud, deep snow, really steep hills, anytime you need max power and traction.
It also explains it in then owners manual.

 

I would add that when you are jacking the vehicle to change a tire, use your parking brake and engage your diff lock.

 

Thanks. Engage it to diff lock hi or low?

 

For chaning a tire? Either will do.
And that metal shoe looking thing that covers your trucks jack, that is a wheel chock.
Make sure that you shift your CDL through ALL the gears once a month so it does not sieze up and not work anymore.

 

yeah because if the linkage seizes up its not the funnest job in the world getting it to work again... but if it does, let us know and we can tell you how to fix it...

 

just curious. Why do we have to put them in diff lock mode when it is being towed or changed tire?

 

NO, don't engage it when you are being towed. All 4 wheels have to be on the ground and the t-case in neutral. Do not drive it while locked on dry pavement.

when jacking up to change a tire: The front and rear diffs are open and the t-case is like an open diff, so really, you could still spin one tire with the diff lock open. with it locked, you have to spin 2. Just safety

 

towing a rover is generally a bad idea...

 

yeah, I guess I should have said flatbed only, on the ground if it is a short distance.
