New Silverado 1500 Crew, Tailgate Issues

We just bought a new 2018 Silverado Crewcab Short Bed last week.  When I first looked at I noticed that the tailgate did not go down level with the main bed (not even close).  I brought this up with the salesman and then later with the sales manager.  We were assured that they would have this fixed before we picked the truck up.  With the tailgate lowered, the left cable was taught and the right cable had slack in it.  When my wife picked up the truck, the service department gave her a copy of the service bulletin that said that this was just normal build tolerances and they were not to try to fix it. 

 

There are 16 quarters under each end of the straight edge in these pictures (height of 1-1/16").  There is still a gap under the straight edge at the tailgate even when I put my full weight on the rear left corner of the tailgate.

 

The total load capacity for the truck is 1,699 lbs.  Allowing for a driver, one could haul 1,500 lbs in the bed.  If this was 3/4" plywood, or 2 x lumber 8' long, 750 lbs would be at the front of the bed, and 750 lbs would be on the very rear edge of the tailgate, with more than 375 lbs supported by the left cable.  HOW IS THIS NOT A SAFETY ISSUE?

 

In reading the other threads on this issue, it appears that Chevy / GM has had this problem for many years.

Silverado Sid and wforrest08:

Do you know which assembly plant made your truck?  From what I looked up online it would have been Flint, Fort Wayne, or Silao Mexico.  Mine was made in Mexico.

99% of 1/2 ton crews are assembled in Mexico (including mine) all double/singles are assembled in the US. 

A extremely small percentage of 1/2 ton standard bed crews are/were assembled in Flint.

Thanks guys.

 

These pictures show that the hinges were attached to the bed 5 quarters (5/16") too high for the tailgate to be level with the bed at the hinge point.  It's exactly the same on the right side.  The top of the tailgate is perfectly flush with the top of the bed sides at both sides

 

But, if they had installed the hinges 5/16" lower, that would jack the rear edge of the tailgate (in a down position) up another 3/8" or so.

Finally, someone who thinks like me! I posted this same question/issue when I picked up my truck a couple years ago. Most truck owners are totally ignorant to this design flaw.

 

 

I frequently haul lumber and noticed immediately that the tailgate is installed stupidly. My old 1998 truck had a perfectly level surface for hauling. I went back to the dealer and asked questions, looked at all the other trucks. They are all built this way. I agree that it is a safety issue, the cables should not be holding up half the weight of a load. I even looked into fabricating my own cables to rectify this, but that was no easy task. Anyway, I couldn't find a real resolution, but I did find these nice little extender clips that I have enjoyed using: http://www.ridertailgate.com/copy-of-gm1-tailgate-lowering-link-set/

These actually lower the tailgate a bit below level, but it makes for easier loading. If you have a long load, you can insert a 2x4 across at the outer edge of the tailgate to support it.

I also looked into the cable strength issue. I forget the exact numbers, but basically those cables are stronger than any load you can put in the bed. You would buckle the tailgate before a cable broke. As soon as a couple hundred pounds of load are on the gate, it will flex so that both cables are taught.

 

Either way, I don't want to rely on the cable to hold up 1000 lbs while driving down the freeway either, the bed should be doing the majority of the work.

Andy, is your truck a crew cab?  Built in Silao Mexico (it would be on window sticker)?

Yes and Yes.

All the beds do this.  Short, Standard and Long.  They've done it on prior years as well.  Tailgate can hold quite a bit. 

 

If I had 4x8s to haul, I'd get a bigger bed or bring my trailer...

#PIT5570A: Tailgate And Cargo Loop Capacity - (Oct 16, 2017)

 

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern

A Customer may ask how much weight the tailgate or cargo loops can handle.

Recommendation/Instructions

The tailgate can handle 1000 lbs. evenly spaced across the entire tailgate.

 

The cargo loops, located at each corner near the floor of the bed, can handle 250lbs each. (This is not the Cargo Management System) 

 

Please note if using ramps (example: Loading ATV's, Lawn mowers, etc.) it may be necessary to remove the tailgate and place the ramps on the bed of the truck. Ramps do not evenly space the load across the entire tailgate and can overload the tailgate

 

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Also if the vin starts with 3 it’s a Mexico built truck if it starts with 1 it’s a US built truck.

This is the problem. When hauling lumber or any thing that is long and flat, you lay it in the bed, but the angled tailgate makes half the weight go on the tip of the tailgate and the other half of the weight sits on the front edge of the bed. It is impossible to spread the load evenly because of this poor design. A properly designed flat tailgate would let 75% or more of the weight lay on the whole bed floor, and the rest would be evenly spaced across the entire tailgate.

 

I really don't understand why the engineers chose to make this the standard configuration, when a decade+ ago, all tailgates were flat/flush with the bed. I don't see one benefit from making the tailgate "angle up". It is a really stupid change.

From what I'm seeing, I do not think that this was an intentional change.  It looks like sloppy dimensional tolerance control for the bed build, the tailgate build, the locations of the cable anchor points as well as the cables themselves.

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.

      OCI, not when but why?

      Unless you are using a bypass filer system with a Beta of 1000 at 2 micron the commercial filters we have access to, even the very best of them, are poor at the 5 to 10 micron range the typical UOA test can 'see'. Point is there are some truly awful filters being sold A 45 micron Beta 75 filter is what Dyson used to call a screen door on a submarine. That leaves wear metals disconnected from filtration unless particulates are larger than the test can 'see' and yet captured by the filter...which is its job. If that is true then you have a major issue screaming at you.    The graph isn't mine. It belongs to GM and their study on this area. I looked up those studies and provided those SAE tech paper addresses multiple times. Machinery Lubrication displayed it and confirmed it. So if you have doubts about the study you'll have to take it up with GM Engineering. Just like you would have to take up a difference in opinion about the meaning a word with Webster or the length of on inch with the National Institute of Standards and Technology.      Most manuals have two schedules. "Normal Service" and "Severe Service". On it's face it tells you that oil in severe service is more highly stressed and doesn't "Last as Long". The item to bore in on is LAST...what does that mean?    It's the same question one asks about how long to toast bread. What are the inputs? Bread type? Wattage of the toaster? Distance from the elements? What is your preferred level of done?    So lets paint this with a broader brush. Oil is made up of the base and the additive package. The first is altered by heat and oxygen and later is sacrificial with a finite life subject to inputs toward that end. Resistance and supply.    It is the reason an OEM's OCI's are determined by 1.) the specifications of the recommended lubricant and 2.) risk management toward the bottom line. Those lubricants are also subject to cost effectiveness for the OEM.    There is a tendency for most people to believe that the OEM recommended oil rest on the top shelf and that anything other is lesser than. Truth is there are more oils on higher shelves than those on the lower shelf below the OEM's. They make that choice on COST TO THE OEM. Testing is incidental to the margin.    GM makes MONEY, the car/truck is a TOOL to leverage MONEY. Insert whatever car brand you like. Until you forking over a million plus COST not quality is the driver. Thus it is by DESIGN the recommended OCI's and oils fall well short of 'best practice protections'. Proof isn't hard to find. GM Ecotec I-4 2400 breather system and cold start PCM tuning has killed more motors and resulted in more litigation for those that used the 'recommended' practice than GM could bear. What was their response? SHORTEN THE OCI. TWICE.    I don't know how long to leave oil in an I don't know how the oil will respond to MY circumstances and because I don't and can't blanket statement or anecdotal evidence my way out of it.....I TEST and FIND the right OCI for the oil I CHOOSE. There is no shortcut but there is blind allegiance. I don't blindly trust anything.    People hear the word 'detergent' and believe that in the context of oil it means the same thing as laundry soap... Only in the most rudimentary way. It's the first additive to give up on you and they are putting less and less with each new API standard. Solvency can be used but it cost. Some unique undisclosed chemistries can be used. Valvoline R & P in example. OEM's haven't an interest in anything they see as limiting market participation. Whatever.

      OCI, not when but why?

      By KARNUT · Posted

      For some unexplained reason my father wanted a salvage yard. As we were getting the family business off the ground one brother ran the salvage yard. We gathered there when rained out working on pipelines in the eighties to pull parts. Perfectly good running vehicles would come to us simply because they wouldn’t pass emissions inspection. We were able to swap parts and sell some of them. I got a clean old nova with a bad engine. I pulled a perfectly good small block out a Camaro. A father and son project with a rebuilt engine. The son couldn’t get the engine running right. The problem was the spark plugs weren’t gapped. The 90s vehicles probably widened the gap of shade tree do it yourself engine repair. My do it yourself hot rod repair stopped at the 70s. After that my trusted mechanic kept them in running shape.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.

      Are we talking about the same thing, though? The 7 versus 3 wear metals was from Lakespeed's 3.0-specific oil brand comparison test between AcDelco oil and Mobil ESP. The filter remains a constant so whatever excess particles the AcDelco oil is producing aren't being filtered out.   I'm assuming there's a parallel comparison to be made; IF the filter can filter down those particles, engine life increases, and your graph makes the case that a better filter (lower micron rating) can increase engine life. Introducing fewer particles AND filtering those particles with higher efficiency is the best of all worlds. Good oil, good filter.   Where we may disagree is the "baseline relative engine life". I'm more apt to believe the base engine life value is 200k+ on very average oil and filters, "bulk oil of unknown brand and white-label generic fleet-grade filter, Jiffy Lube"   Going from a 10 micron filter to a 5 micron filter should boost a base 200k to 275k in a vacuum as a single factor alone.   Here's the whatabout: How does regularly changing the oil and filter ahead of recommended schedule influence baseline engine life? Most people aren't going to science the heck out of this stuff or ask about Micron ratings, HTHS, or wear comparison tests at Jiffy Lube. Most of the Jiffy lube techs would say they need to call their tech support line to even try to get an answer.   --   Because we love anecdotes here, when I was fishing for 4.3 parts at a local yard this weekend, ALL of the 4.3 vehicles had well over 200k. I love looking at odometers of junked vehicles. How far did THIS go before landing at the crusher? The ones that still had engines weren't seized. None of them were vehicles I'd consider were Amsoil queens, in fact most of them had some kind of service cling-sticker in the corner of the windshield indicating it probably had very average maintenance services. Even the fresh parts rigs- I'm not sure taking an S/T series to 400k has much value considering the running value of those vehicles was probably somewhere around $1,000. 25+ years is a good run on time alone.   The intake manifold I salvaged had clean and bright pool areas. As expected, I found the fuel lines in the manifold rubbed through, just like mine. I'm guessing the lines on that donor truck started leaking, the truck started running rough, and its owner said that's enough I'm unwilling or can't take it out of service for several days, or spend $1000+ to repair it at a shop, it's simply time for a newer more reliable vehicle (or, more than likely, this is the 2nd, 3rd time this has happened in the truck's lifetime). While I don't count on my Blazer for reliability, the thought of giving it away for parts at certain points during my adventure, and being mentally free from its needs has has crossed my mind. I'd be losing $1500 or so, but I can only make more money; not time.
