When I first got my truck the ez lower tailgate on my 2014 GMC Sierra sle was working just fine but just recently I left my tailgate open for a day and now when I open the tailgate it slows down but not quite at the rate it used to. Now it some what bounces a little when I close it fully and open it .Before it was a nice and slow and now it drops fast enough to bounce a little. I was wondering if I could fix this myself by tightening some things or do I have to bring it into the dealer to get it fixed

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

Some owners may comment that their EZ Lift and Lower tailgate opens too quickly. The average time for the tailgate to open is approximately 2-6 seconds. If additional add-on equipment has been added to the tailgate, this will affect the rate at which the tailgate opens. Examples may include such items as a bed liner, tailgate mat, etc.

Additional information on the EZ Lift and Lower Tailgate components and functions:

EZ Lower - There is a dampener attached to the right tailgate hinge, and it can be accessed by removing the right tail lamp assembly. This dampener is only used for the EZ Lower feature and does not provide any assist when closing the tailgate.

EZ Lift - The left tailgate hinge incorporates a torque rod. This torque rod is only used for the EZ Lift feature, and does NOT provided any dampening for the EZ Lower feature.

If the tailgate opens within approximately 2-6 seconds, no repairs should be made.

Note: Add-on equipment may cause the EZ Lift and Lower tailgate to open faster than the normal 2-6 seconds. Such equipment may also require additional effort to close 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.

Mine has broken twice. The dealership fixed it under warranty. They said the tailgate was too heavy for the design of the ez lower system.

Mine lowers sometimes that fast.. I will probably replace it soon. That bulletin seems like an excuse, these trucks are coming with factory spray in liners, so the ez lower feature should be strong enough to still open slowly.

Just my two cents

During warmer ambient temps, it drops faster. Try it again in a colder area.

 

Yours dont seem to be dropping too fast though, just as fast as when mine was in a hot day. I thought it was broken too when it was dropping fast and I decided to drive to a dealership to compare, theirs drop just as fast at the samee day.

Mine is falling fast also. Just noticed it. Is it operated by one of those gas damper?

Logically there should be an adjustable torsion spring that would allow the owner to "dial in" just the right amount of assist desired. But that would cost too much for a vehicle with a $ 50k sticker.

That is about three times faster than mine comes down and I am in Florida where it has been in the high 80's for the last week.

Is it possible for you guys with the new design trucks to install an aftermarket DeeZee-EZ Down tailgate assist strut?

They work great on my Silverado's. Couldn't hurt to give it a try. If the factory one fails, the Dee Zee will still work.

Best thing I guess would be to take it to the dealer (should be body 3/36k warranty) and have them put the EZ damper in it.

Here is just a quick update I went to the dealer today and they said it was just fine and to my amazement it did just work just fine. It is a little cooler today than it was yesterday. Maybe it was just the heat but idk now it works just fine. So thank you for all the replies

On the right side hinge, where you tilt to 45* to remove, mine has a plastic insert that is broken and lets the tailgate slam. Keep your eyens on these. I am guessing we will see a lot of failures here.

      Gas Prices

      By PhilB · Posted

      Did you even read this article?   Even the title of the article says "U.S.-Iran Deal Doesn’t Mean a Swift Return of Oil and Gas Flows"   Remember, crude oil prices are based on FUTURE purchases by the oil companies.  Gas prices are based on FUTURE purchases by the station.  This article stated that many of the oil producing nations have to restart their processes to get the oil produced.  Then the oil has to be shipped to wherever.  And it doesn't get there overnight.  And most of that oil is not coming here. Check out this site:  https://afdc.energy.gov/data/10621   A graph will pop up to show where the US imports their oil from.  Notice that there isn't a lot of import from OPEC and Iraq.  Most of the US import comes from Canada. The US oil produces are selling their oil on the open market, which is why the US fuel costs went up.  So you're correct, the US oil companies are going to slow walk the price downward.

      Stabilitrak conversion to Z71

      By teamjnz · Posted

      I just purchased a 2004 Tahoe with 148,******. I used to have a 2006 Suburban that had the push button Auto 4X, 2Hi, 4Hi and 4Lo. When checking out this truck I noticed it had push button but didn’t focus on it. After the purchase when driving home, this is when I noticed it was different and after a little research found out it has the AWD stabilitrak system. I don’t live in an area that requires AWD. I bought the truck to start a new adventure in life with off roading, now that the kids are all grown up. I purchased the truck knowing it didn’t have the G80 rearend but plan on re-gearing to drive on 33s or 35s and upgrade with a rear locker and still be able to tow when needed. Blah Blah Blah Anyway I know am thinking about converting the stabilitrak  to Z71. I know I will have to replace the transfer case. So now the information gathering stage is happening to see if it is worth it. Is the front AWD stabilitrak differential different when compared to a non-AWD front diff? Will I need a completely different front differential or can it be converted? What else should I be considering? I did see something in a video for GMT900 platform with removing the ABS fuse that disables the stabilitrak and turns the truck into a 2 wheel drive. Would that work in the GMT800 platform?
