I am curious to know if anyone else just experienced what I have experienced? If so, how did you remediate the problem?

 

I drive a 2019 Chevy Silverado Custom Trail Boss. The Trail Boss edition comes standard with a 3" lift from the dealership.

 

I ended up getting a flat tire on my way to work on the rear passenger side.

 

I thought, no big deal, I'll just use my spare.

 

(When I am at home I have a 2 ton jack that I use, however, I only had the jack provided with the vehicle at the time my tire was going flat.)

 

I was in a level parking lot (work) when I noticed the tire going flat. It was a slow leak.

 

I took out the owner's manual because identifying how to exactly change the tire with the equipment provided with the vehicle can be tricky sometimes.

 

I did exactly as specified in the manual, placing the bottle jack exactly where I was supposed to.

 

I noticed that the bottle jack seemed to be getting near it's maximum height, yet my "flat" tire was barely off of the ground...

 

I did manage to get my flat tire off of the vehicle, however, common sense tells me that there is no way my inflated, full-sized spare was going to clear enough to mount.

 

Assuming the manufacturer would not give me a jack that did not work with my vehicle I continued to lift the vehicle with the jack. Only two turns later and I saw the jack begin to buckle in the middle. I attempted to lower the truck, but it was too late.

 

The jack buckled and my truck fell on to the rear passenger side rotor.

 

My question(s) is:

1. Shouldn't GM provide a jack that is suitable for instructions provided in the owner's manual?

2. Has this happened to anyone else?

3. Who is at fault here?

 

Thoughts?

 

Thanks,

Nick,

So you put the jack under the rear axle? Factory lift wouldn’t affect this. That being said, I’ve never jacked the truck up high enough to pull the tire off with the OEM jack though it most definitely should be able to handle the weight.

Did the jack buckle or did the truck roll forward causing it to fall off the jack?

If it had the GM Accessory lift installed then the kit should have come with a new taller jack. The stock jack should lift the Trailboss just fine but if the accessory lift was installed it sounds like someone may not have replaced the jack with the new one provided in the kit.

My truck was parked with the front tires against a curb and I used chocks on the rear to prevent rolling. However, I was in a flat parking lot. I don't think it was the weight of the truck that buckled the jack. I think that the jack was not designed to lift this vehicle high enough to change a tire.

BPRIKOLA,

 

Yeah, the Trail Boss comes with the lift as is. I drove the truck off the lot with 10 miles on it and did not provide an after market lift. I was assuming that they gave me a jack capable of lifting the vehicle they sold me.

The stock tires on the Trail Boss Custom are just under an inch shorter than the regular Custom (32.08" vs 33"), so your rear axle is actually closer to the ground than a regular Custom.  You certainly don't need a longer jack.  Maybe there was a defect in the jack.

Yeah, I'll post a pic after work. I positioned the jack just inside the shock mount on the rear axle.

Those factory bottle jacks are crap.

As you found, at extension, they're too weak.

Also, the ram end has NOTHING to grip the axle tube or frame with. Try using that thing in the rain.

It's garbage. You can get a small hydraulic jack and pitch that thing in the garbage. This is GM's fault. Not the first person I have heard say this happened to them.

Sounds like OP used the spot the manual suggests.

Rear Position - 1500 Models
5. If the flat tire is on the rear, position the jack under the rear axle about 5 cm (2 in) inboard of the shock absorber bracket.

I’d be pushing for the dealer to replace the jack and to fix any damage. That’s crazy it buckled. Only if the thing rolled is that even possible.

 

I’m assuming you were able to re-jack the truck with the wonky jack to install the spare? I just looked at mine and other than a touch of rust on the jack it looks up to the task. Need to apply some oil to it now!

Mine did okay when I had the same tire go flat. Not the quickest or easiest thing to operate but it seemed solid enough. I do not have the factory lift though.

I agree with you totally but....

Always carry 2x6 pieces for jacking IMO.

Or a 3 ton floor jack [emoji16]

This is incorrect.  The 2" Trailboss lift kit comes with the EXACT same jack as comes in the truck, down to the same part number.  I fully extended the stock jack and the one that came in the lift kit to compare....they both extended the same amount.  

 

As others have posted, you don't need a taller jack for the TB/AT4....the axle is still the same distance from the ground.  The lift blocks are placed between the leaf springs and the axle.  Truck.goes up....axle doesn't move.

    • Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/        
    • UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update  
    • GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.  
    • Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.
    • I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
