Can you safely put jackstands under the rear sway bar?

[JamesLond]

I lifted it in the middle under the bell housing. I can't figure out where to place them in the back.

If that's not the spot, please let me know the right one.

I’d put the jacks on the actual rearend before I use the sway bar.

Not a great picture, but you can use the differential to pick it up with the jack, and the jackstands can go on the axle tubes just inside of the shock mounts:

Those are 6-ton jackstands and that's the position I used to remove the fuel tank. Twice. Actually it was good experience.
EDIT: here's a better pic. See the red arrow for a good stable location for the jackstand.

well the back lift points been dealt with, now back to the front, you can use the rad support, or the K frame under the engine. or under the ball joint of the lower control arm to do one side at a time.

you made it sound like you jacked up the from under the trannys bell housing, and thats not how to do it.

I would never set a vehicle on a jackstand at the sway bars. They are not designed to hold that much weight. The axle tubes and shock mounts are along with the lower control arms or the chassis itself.

I think he was just calling the rear diff (pumpkin) a bell housing, if I read the title correctly he's working on the rear end.

Yup, that's it. I don't know why bell housing popped up in my mind.

Also, I'll look closer at the spots you pointed out for my other side. I ended up putting a stand on the side frame rail a little ahead of that rear end control arm.

rodger that. just never know when the terminology is off this far lol

frame is always a solid jack stand point.

That is why I always use the term "computer", rather than ECM or PCM... Because, whichever one I think is the right term to use at the time I am posting I'll probably pick the wrong term. So you might notice I completely ignore using those terms and just stick with "computer"... Fewer complications for everyone, when I dumb it down for my own good! LOL

Please note: I am in no way suggesting anything about the mix-up on use of bell housing by the OP! Simple mix-up in typing. I was just poking fun at my own inability to correctly recall whether or Tahoes use an ECM or PCM, so I completely avoid the issue...

ECM in its true first use was used in 1981 up to when GM needed a computer to control the transmission (4L60E) too. A PCM controls both the tranny and engine. For some odd reason in 2007 GM decided to split them up again and 07 GM truck chassis have a ECM (engine) and TCM(transmission).

Thanks for the clear breakdown on what is what for which models!

Hah!
It seems that I will never be able to keep it straight every time I want to mention it, because of some disconnect between my brain and my typing fingers.

Knowing when to surrender is the sign of a smart warrior. Since I have lost that battle, so I'll stick with calling it a "computer". At least, technically, I won't be wrong! LOL

 

[JamesLond]

I see the spot now.

On the driver side you have to put it between the opening in the parking brake cables. From first glance I thought the cables blocked everything.

On the passenger side it's nicer since there's no cables you have to move.

i hear ya. so heres how to figure that out, pcm is a power control module. it does the trans and engine. ecm, engine control module. does just the engine, then you also will have a tcm, trans control module. main issue with this info is knowing what cars/trucks use the pcm, or ecm. our years trucks have a pcm. if you can see the pcm or ecm its a dead give away. pcm's have two long plugs, and the module is large, ecm's are small and have two square plugs.

PCM= Powertrain Control Module

GM has been pulling a Ford/Dodge lately with how many different odd things they are doing with electronics. Hopefully we never end up with the wiring problems of Dodge!

Just don’t jack up the computer and you’ll be fine.
