Jacking Points

I’d like to jack up my 2019 RST Suburban to paint the brake calipers. My garages are too small to use my hydraulic floor jack.  Using it of the ~flat StaMat (crushed slate) garage apron is a bit tedious as I need to ensure that the jack pad stays on the frame jacking point, even though the jack doesn’t roll very well.  The OEM jack is the cheapest design built by the lowest bidder.  The forward jacking point doesn’t even have a pocket or recess to  keep the OEM jack from moving.  

 

Anyone see see a problem with jacking the front end by the lower control arm / shock mount, and using the owners manual forward jacking point as the location of a jack stand?  First one side and then the other?  Any other suggestions?  Couple of bottle jacks or something?

 

While on the topic, why is it unsafe to use proper jack stands to support both ends?

The lower control arm would be fine, I'd think.  I'd still use the floor jack instead of bottle jacks, especially on crushed gravel.  Maybe use a piece of 3/4" ply to roll and for a wider base.  I've never heard of it being unsafe to support both ends with properly placed jack stands.  I do it all the time with my Wrangler or anything I'm rotating tires on.

I would not use a bottle jack when trying to lift using the LCA from an extended position, as it travels through an arc, not straight up (which happens when you are lowering the truck).

I was thinking of lifting the Suburban tires off of the ground, just high enough to remove them.   Using the frame lift point, you need to go up further to get the wheel just off of the ground...  A bottle jack under the LCA, starting with the wheel on the ground, would need to rise only a couple of inches to unload the tire.  I’d use a jack stand or 4x4 blocking as a backup for the event of jack seal failure or something.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
