02 Suburban Rear Jacking

[OR VietVet]

I will not jack a differential at the tubes unless right at the ends, as far out as can. Otherwise, jacking at the diff is fine.

Thank you! 6 ton stands are what is being used. Here’s a picture of where I have the jackstands right now by the axle. Just don’t like how the surface of the jackstands isn’t totally engaged, only half of it is. Even putting the stands under the doors makes them want to tip, which I think may be due to the jack not rolling. I’ll put my hardwood sheet under the jack and see if it rolls properly.

Need to turn the jack stand 90 degrees. The round axle tube should be down in the rounded part of the saddle.

No matter which way I put the jackstands I can’t seem to get it to a great spot. By rounded part of the saddle do you mean on the jackstands? I don’t think they’re curved enough to really grab it super well.

The weight of the axle will set it down in the rounded part of the jack stand arm saddle. Are you on level ground? Does all 4 wheels of the floor jack roll smoothly?

Oh so are you saying that I should try to get the jackstands to grab the entire diff area and not just the small circular area I put it on? The area I put the stands is a bracket that comes out of the differential where the sway bar brackets go. Can’t go right on the axle tube because the sway bar is in the way.

Yeah, there’s no way for me to get the jackstands over the whole area on the diff. Sway bar is way in the way.

Here’s a video of what I’m talking about.

Get some stands to set the tires down on/in. They come both with, and without, ramps. What's wrong with the 'stands under the frame rails' idea.

The way the stand vs axle positions in your video looked to me, there's no effin way I'd crawl under there.

The stand's 'saddle' does not need to 'grab' the axle. If you get the axle centered in the stands, weight and gravity will keep the axle from sliding up hill off the stands.

And lube those wheels. Work them so they'll roll and swivel.

Yeah there's just no way to get the jack stands where they need to go. Only reason I went under is because the jack was supporting it as well as the stands. Will lube the wheels, what do I do, just smother a ton of grease all over them and roll them? They still swivel just don't roll like they should.

And whats wrong with the stands under the frame is that that I literally can't get them to not want to tip over. It's very weird.

Ok, first you are using an unsafe floor jack with no pad and the wheels will not move when rusted. Way unsafe. You are asking for a problem with that floor jack. You should not be lifting this with a jack like that. You ask for safe procedures and then you show the messed up floor jack. Get that out of there.

Second, inner parts of the tubes, where they come out of the diff have enough room where the sway bar bend is to allow for the stands to be placed as I stated. Or at the very ends of the tubes where the sway bar ands may allow enough room. If none of this works. Spread the stands out to the ends and set the sway bar itself in the curved stand arm saddle. Or, set the rounded part of the sway bar attaching bracket in the curved saddles. If the sway bar is directly below the axle tubes, setting the stands under the sway bar or the brackets, will not hurt it. If the sway bar is offset and is either forward or backward of directly under the axle tubes, do not sent the stand saddles under the sway bar.

WD-40. Grease. Motor oil. Something. They need to roll and swivel. Work it in, don't just cover the outside.

And I've seen too many floor jacks bleed down to trust one with me under the truck.
