If you have all the tools and have an inkling of what you are doing it's not too difficult. The only problems I incurred was the fact that the computer has to be flashed after it is installed and possibly a couple settings might have to be changed and secondly the truck will need an alignment afterwards which is not something that's exactly in my wheelhouse. Other than that it was rather easy and straight forward! I wish you nothing but the best, mine seems to be holding up pretty well and I am trading it in today for new Denali Duramax! So it'll no longer be my problem...hopefully! 

Before I dig myself into a hole. Did you just drive the truck back to the dealership to get them to flash it. Or will the steering not work before it is flashed

Wow. I am sorry about me taking my time to get back to you, I usually get an email with an alert but regardless I was able to drive it to the dealer. However, the service manager seemed a bit surprised the truck even started. So it may be a case to case basis? Who knows with all the damn technology in these trucks anymore.

When you drove the truck to the dealership how was it? Any issues with the power steering?

I didn't have any issues at all! But again. don't rely on me completely, don't really want that liability. LOL

Hey guys, 

 

I have just got a 2014 sierra with a 2.5 in level & 305/55/20's with 46K miles. Getting the same issue with the gear mesh/binding/clunking noise. I am trying to see if there is a new rack and pinion or if the part number was fixed in the 2015-2018 production runs. I know the supplier had to have been made aware of the issue. I am trying to get this covered by GM as there are proof of other individuals getting it covered. But I also entertained the option of doing it myself. I would have the truck aligned afterwards but as far as computer work/calibrating, what needs to be done? 

 

Thanks,

Im on the same boat, 2.5 lift 275/60/20 and the clunk noise... thinking maybe installing Moog iner tie rod and see if it help at all.  Did notice the rack moving a lot when turning Left, it does not move at all when turning right?

Was that with a rough country lift?

Yes sir. 

So add me to the list. 

I have a 2015 sierra crew cab with a 2.5" rough country lift. After putting on around 25k miles I started hearing a dragging, clicking noise in the steering wheel. Dealer says I need to replace rack and pinion for 2400k. I am afraid I'll bite the bullet and be right back here in another year or two. I was told there is a 2 yr warranty on the replacement, so I might gamble on that.

Wondering if this is specific to a rough country lifts? Anyone else had this issue with other brands or with NO lift?

I think any lift would do the same, $2400 is a tuff. You can by the rack for $1,050 at gm dealer online, install is not bad but i think it needs to be reprogramed to cars computer. Part # did change for 2016 and up so maybe its a better one?

Hello all, we installed lift onto my sons 2015 Z71 height and lift manufacture I don't believe relevant here. clunking noise started also, when he took to dealer they told him they did the recall thing that didn't fix anything, then the steering went out all together, we decided to remove rack and pinion and disassemble we found the belt for the electric motor had broken. The PN on the belt is 28271802. We cannot find this belt unless you order 100 from china! As someone here has all ready said I think we'll buy a new rack and pinion and sell this hoopty.

I just put a RC 3.5" on my 2014 Silverado last month. I also changed lower ball joints and outer tie rods. I began having the popping when I turn left at slow speeds. I first thought it was a ball joint that had failed and went to replace it yesterday. Upon crawling under it yesterday I realized the ball joints were fine. As I was investigating I noticed the popping in the tie rods and figured I need inner tie rods. Replaced the drivers side with no problem, there was play in both sides, when I pulled the passenger side inner tie rod I found what looked like 2 washers on the rack and pinion shaft. I am assuming this is the piston seal but I am not positive. I have no leaking  of fluid that I noticed. I put it back together after I removed the 2 washer looking pieces and the popping is gone. Not sure if anyone else has had this happen or knows if I should be concerned. I have no issues steering but I am clearly concerned of the steering just locking up. No one makes a rebuild kit and it looks like it's going to be about $2500 to get it fixed but sounds like it's difficult to get ahold of a new rack and pinion. Any suggestions are greatly appreciated.

 

 

 

Update: after much internet surfing I came across this you tube video that gives the solution and a part number which you can order from oemgmparts.com for about $23. This is way better then $2400 to replace the whole rack. Here is the GM bulletin as well for the repair.

Great information!  Having the exact same issue with my 2014 Silverado.  It looks like the service bulletin link may have been the wrong repair.  Do you happen to have the correct one?  Thanks again!

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
