2015 sierra front suspension problem

Hello, it's my first time on this Forum and i find it very interesting.

 

I have a problem with my Sierra 2015 crew cab 4wd with 6'5'' box with 18 inches wheel. It has 4000 km on it so its new

 

I bought it in august and since then I have a problem with the front suspension. The suspensions knocks at full extension in holes or after a bump. The front end is very unstable, it seems like there is no rebound damping at all. The suspension set up is not what you could expect of a half ton 50 000$ truck.

 

The ride is horrible on bumpy roads. At slow speeds the suspension sometimes lifts the front wheels off the ground. The suspension is so bad that it does not allow me to go on gravel roads to my hunting camp.

 

I did a test with my 2006 Honda civic with 200000km and it on it with 15 inches wheel and on the same road and the suspension worked very fine. I did a test with a RAM 2007 and a Ford 2014 a chevy 2009 and I almost didn't fell the bumps. I dit the test on the public asphalt road in front of my house at legal speed limit.

 

I took it to the dealer with 1800km on it. They try it and they recognised that there is a problem but they told me that the truck is built like that. I should buy rancho shocks and pay nearly 1000$. My understanding is" we sold you a cheap truck the contract is sign its your problem now"

 

It is my firs new vehicle and i am very diapointed with this truck. I paid 50000$ and I dont even have the ride of an old civic. Its like buying a new truck but the brakes doesn't work and you have to change them before you go out of the dealer

 

It's my fourth GM truck and I have always been satisfied but this one is probably my last. I have never paid so much for truck and i was expecting way much better ride. I drive this 98% of the time on highway public roads.

 

I know what I'm talking about I Have been working for the Ministry of natural Ressources and i drove all kind of trucks in all kind of roads over 15 years but i never drove a truck that the front suspension was that bad.

 

I should have tried it more than 10 minutes before paying that much money shame on me! I had too much confidence in GM!

 

Since the dealer will not help me, where can I find good front shocks at a decent price?

 

Can the Bilstein shocks fix my problem?

 

Thank you for your answers,

It sounds like there is something wrong with the coil struts on your truck. I would contact GMC directly and then find a new dealership.

Your issue isn't typical but keep in mind too that your truck isn't a honda. It will NEVER ride as good as a car but it should ride nearly as good. You need to take your truck to another dealership. These trucks do ride nice. Something isn't right and it's up to the dealer to fix it. This shouldn't be rocket science here.

There is a simple way to improve the ride stiffness by installing softer shock absorbers. You do not have to spend anywhere near $ 1000 on them either. If your truck has Z71 suspension, then the OEM shock absorbers will be quite stiff.

      J&L OIL SEPARATOR CO

      By Grumpy Bear · Posted

      Just did an injector/HPFP replacement on Pepper at 192,400 miles; close enough to 200K, RIGHT? (If 200K is considered life end and to me it isn't). But hey, to each his own.    Have never run a catch can on this vehicle. Back side of every valve looked like a new valve spray painted semigloss black. Port walls looked 'neat' (all a normal result of passive EGR via VVT) Zero build up even in AFM cylinders. Just color. It uses no measurable oil and never has.    At 155,000 I put her on E-85 and a borescope of the cylinders at plug change showed very clean pistons and valve faces. The replaced injector tips looked new. (It was the pump piston seal that was leaking). Oh well, have six good backups.    Still gets 28 mpg on gas (highway average) and over 20 (highway) on alky. UOA's look good and runs as good now as it did when I bought it. Better in fact.    What improvement would a Catch Can provide this motor?     And given all this I expect that IF I installed one I'd see some water/gas/oil vapor accumulation. Byproducts of normal combustion.   Having said that, IF my motor used an appreciable amount of oil I'd consider it a useful 'crutch' until I had the situation corrected OR if bore polished, until I junked it or rebuilt it to stave off repeated plug fouling.    I'm not telling you what I THINK. But what its DONE.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By Grumpy Bear · Posted

      Love the look. I'm a SCSB lover myself.    Two items. 1.) A spacer changes scrub radius but this also changes when we use wheels of different offsets. A little isn't a big deal. 2.) Steel wheels, alloy wheels all have different thickness. Same effect on the stud and lug nut as a spacer. When hub centric the wheel isn't supported by the stud. It's supported by the hub. The stud just keeps it all together.

      2016 Sierra 5.3L L83 new injectors now runs rich.

      By JAI3 · Posted

      I had a evap sol go bad a couple weeks ago. . I replaced it.  While watching live data at the time I saw I had some cylinder 1 misfires. No MIL but on live data I could see ~50 at startup and about 70 more after an hour a drive all on cyl 1.  I also noticed that the LTFT were -5% to -15% always.  And that bank 2 is always -3% richer than bank 1. Even across all driving modes, city, highway, etc it’s always 3% richer than bank 1. So I start with the misfire. Swapped coil, plug, and plug wires from 1 to 3. No follow. I got an Injector reseal kit, pulled the D/s injector rail, swapped #1 and #3 injectors, resealed them, reinstalled and retested.  The misfire followed to 3. So I ordered and replaced all 8 injectors, spark plugs, and plug wires. Also replaced the 1 time use fuel pipes under the intake manifold.  Injectors that were in the truck since new were  Part # 12668390.  I replaced them with # 12742701 Got from RockAuto. Pretty certain they’re genuine and the correct ones. I called a friend at a parts store who told me “the 12742701 were the correct superseded part # for the originals I was replacing”. So started truck after replacing all that and it’s running -15 - -30 LTFTs. I reset the fuel trims with GDS2 and drove it for a 60 miles trip each way. There have been no changes in the LTFTs.  I checked if the HPFP was leaking into the crankcase. I removed the pvc and watched the trims. No difference.  I checked the alcohol content and it was at 10%  I’m out of ideas here. Truck seems to run great. Just always rich on the fuel trims.  Anyone with any help or ideas would be greatly appreciated.  I ran an injector balance test just for the heck of it and it came back this. I’m confused.  I have gds2 and some other diag tools if anyone knows of anything I should test next.
