Good Evening,

 

I am interested if anyone has any information about frame changes on the Sierra 1500's from 2014 through 2017.

 

I just purchased a 2107 and it has an unbelievable stiif harsh ride and I am being told they beefed up the frame. I traded a 2014 Sierra that had an extremely nice smooth ride and not at all harsh.

 

Does anyone out there know if in fact the frame was changed since 2014? It would be good for me to know. Thanks in advance

I don't think there have been any frame changes on the K2. Was your 14 the same model as your 17 (aka Z71, max tow, 4x4)?

Both vehicles had the same suspension package. Both build sheets the same . 60 suspension package . XLT 4x4, identical vehicles except the new one has the optional brake controller. It does not have the. Mac trailer package which would have been heavier leaf springs . I have gone from Good Year Eagles LS2 to Michelin LTX ms2, to Michelin Premier LTX 's to try to soften ride. Have to run 30lbs pressure to get half acceptable ride . HELP

Apparently, changing the struts/coil springs/shocks is too hard, and we would rather come here and constantly complain about it.

Note that shocks with 3 years and 36,000 miles (estimated) will ride significantly differently than new shocks.

 

If you don't like the ride, something has to change. Just asking about frame changes won't fix it. Seems like you have about three choices: 1) get a different vehicle 2) get 17" or 18" wheels and tires 3) get new struts/coil springs/shocks. And you can combine any of those three as well.

 

If you think the truck is the issue, test drive another equivalent one on the dealer lot. If you really think the frame is the issue, talk to the person that gave you that info and ask him to back it up. And even if the frame is the issue (which I don't personally believe it is) you're still left to the three choices above.

Oh Rick, I guess you are right. People should expect to have to change struts,springs and shocks if they buy a new 2017 Sierra. They should just list it as an optional equipment .

 

Z60 on both vehicles.

Mine is a Z71, and rides very well. It has the 20" wheels. You are definitely in the minority here. Most guys rave about the ride and overall comfort these trucks provide. Since you are obviously irritated with the ride, your only recourse is to change the wheels/tires, then the suspension components. Your dealer is inept if they can't or won't figure out how to satisfy you.

Rick, I compared the z71 parts and found that the leaf springs are the same on the Z71 and my truck. That leaves me to believe that the only difference is the Rancho shocks and a rock cover. Is that correct?

The front spindles are Z71 and Z85 specific. The others use another part number.

 

There are 4 different front coil springs listed for non-magnetic ride control equipped Sierras

 

Upper and lower control arms are Z71 and Z85 specific. Other trucks use another part number.

 

There is only one part number listed for the rear leafs, but 4 numbers for shocks.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.
