Jack placement
« on: September 10, 2016, 06:29:25 am »
Where is the safest spot to put a jack to raise both rear wheels? Is it safe to place it under the rear diff.?

How about to raise one rear wheel?

And how about for the front wheels?

i always jack by the rear dif. the front depends on 2wd or 4wd. 4wd as close as to the center on the axle, most times it only lifts the drivers side more but eventually you can get the passengers side up. 2wd, has been a good bit of time but i want to say by the crossmember

Right next to the rear diff, but not directly under it?

Floor jack-- chock wheels to keep the truck from rolling

2 wheel drive, front I use the frame member under the engine for both wheels, under lower control arm spring perch for one at a time.  For the rear right center underneath the differential pumpkin.  Under each shock mount if you want to do individually.

Between 5 and 6K I think. What jack did you get? I have a 3ton (6K) jack and it holds the truck no problem. Haven't found anything yet it can't lift.

Just a basic 2 ton for small quick jobs. They had some nice bottle type jacks, but too small and dangerous i think.
(The point of contact being too small)

want to say the curb weight is a little over 4k. the gvwr has to be under 6k for a ½ ton.

Should be fine. 2 ton (4k) is still alot of weight, your not going to pick up the entire truck at one time so you will be fine. Just use jack stands and be safe. The jacking instructions in the owners manual are actually very good.

Make sure where the vehicle is parked is level , chock the front and back of the wheels that are staying on the ground with actual rubber wheel chocks , not rocks bricks or firewood
You'll need at least 4 chocks for this

Always always place a sufficiently sized quality jack stand under any vehicle after you raise it
   The small ones made in China might not be what you want to use

Large wood blocks are acceptable for stands
If you have plenty of 6x8 x16 blocks of wood to stack underneath
Lay two flat on the ground next to each other then lay two more on top of those in opposite direction

Then after the weight is lowered into the jack stand , stand up , and shake the vehicle as hard as you can side to side and front to back to make sure the stand is not going to fall over

And if I'm removing a wheel I always lay the wheel/tire flat and slide it under the vehicle

That way if the jack does collapse the vehicle won't fall totally flat on the ground

The thickness of the wheel may just keep you from getting squished
