    Default Using diff as jack point?

    Can I jack up the rear of my rig by putting a jack directlhy under the differential? Somebody told me yes, ut I hav nightmares of the axle snapping in two. Can this safely be done? Thx for any solid info.

    Yes you can the diff is incredibly strong. Make sure that you put Jack stands under each side of the axle so it wont tip to either side..
    There is no problem lifting from this point.. Most likely it is stronger than alot of other points that people use to lift from..

    For safety reasons though, after it is raised to the desired height I would throw some jack stands under each side. Though I am paranoid...

    Yes, jacking a vehicle up by the rear differential is perfectly fine, as it is one of the strongest parts of the vehicle. However, like everyone has also said USE JACKSTANDS ON EACH SIDE OF THE AXLE TO ENSURE YOUR SAFETY. A falling vehicle is VERY heavy, I don't think you can benchpress 3000+ pounds.

    Here's a picture of how we jacked up the rear of my 2500HD, not a problem and very steady!
    If your axle does snap in half then you have other issues LOL!

    BTW- Watch put for loose lines or cables, the emergency brake cable is very easy to pinch with a jack stand.

    Just can't use a wimpy jack as you are picking up twice the weight compared to jacking up one side at a time...jackstands are a must!
