Ok, I am new to this site but as a GM tech who has been pushed too far, its time the truth came out! I know for a fact in the northeast, there is a service bulletin #PI056E: and its titled wax coating

That's not acceptable! Looks like it was done by a blind man. I'd be back there demanding to know why they had the truck for 3 days and that's all they accomplished. I sincerely doubt it's GM's fault,

Well, now you see the GM manufacturing trend for these trucks. The idea is to produce a comfortable vehicle with a car like ride, silent interior, and loaded with gadgets. This is bound to impress t

Have a 17 dealer did the undercoating from new plus a rust module no rust yet and I live in Nova Scotia where there's lots of winter salt

If you live in Nova Scotia and have no rust, whatever it is you're doing is working.

That's the problem with these frames, unless you strip all of the GM frame wax off, paint, then apply some sort of corrosion inhibitor...it just isn't going to work. Everything else is just band aids. All you can really do is try to slow it down...do preventive maintenance...keep that metal covered in something...and do it frequently. I actually Fluid Film my truck twice a yea - - and even then it's not enough  - I still do some touch ups when I do my oil changes...and believe  me it needs it. There's always a little piece of bare  metal exposed and I'll just cover it up with some white lithium grease (it seems to stick well and hold up). 

 

Just keep up with it, it's not a one time set it and forget it, thing, it takes some work. And that's true for ALL trucks...painted frames, rubberized coated, you name it...they all rust. It's just a matter of how much it bothers you and how much you're willing to slow the rust down. Right now my truck is only two years old...I'm still in love, but that will stop some day. I won't be so anal about treating that frame and believe me it will quickly rust. Good thing is, the frame has so much metal on it that in all honestly it will take probably 20 years to rust through to the point where you'll need repair (and you can repair these things professionally - a welding shop can handle probably 90% of these frames safely).

I live in NL and you typically see rust after the first winter, the ranchos show first sign, then chassis.

I just sprayed on flat black rust paint on spots on my 17 High Country 6.2L and it was undercoated new and has rust module. 

What is a "rust module" ?

the "new" rust modules from DiamondKote, plugin to the OBD2 port. I would suspect these are even less effective. Regardless, like High Country 6.2L/8 has mentioned, when you live in places that salt/sand are used to cover roads, and theres always moisture, and salt spray in the air - you opt for as many products as possible.

Your correct maybe rust module isnt effective on it's own or at all but the combination with undercoating helps can't hurt in Canada. Thanks for comment

np. I've used Krown protection, with the rust module, but after 3-4 years, the chassis needs to be wire-wheeled down to the metal, and a new coating applied. It is inevitable.

POR-15 is very popular around my parts. especially in a rebuild/chassis stripping project

That's what I'm afraid of after awhile. The truck is 3 years old and none yet crossing my fingers something is working. I should add it's not a work truck and I can pick and choose when to drive it.

      2001 GMC Sierra - Banging feeling in steering wheel

      By txab · Posted

      Without knowing how bad your banging is, one suggestion is the intermediate steering shaft on the steering wheel. These used to be a problem on 800 and earlier series. The feeling/sound was sometimes described as "clunking" and was felt in the wheel. Also there is a plastic piece in the lower column that is referred to as a bearing. Not your traditional looking bearing though. Your ball joints, bushings and tie rods or steering rack (if equipped) are the main point of issues. You never mention total unit miles, only that you've put 60k on it.   You can search the site for help on the ISS description. Plenty of these have been replaced   https://duckduckgo.com/?t=ffab&q=site%3Agm-trucks.com+intermediate+steering+shaft&ia=web

      Yes I have is set with the 1mm disk (Minumim Tension), for spring spacing and I raised my truck in the rear 1.5". You can go 2mm  and I think 3mm if you need.Minimum. We are on our way to TN from GA.. My wife is driving and stated she cannot believe  and   stated she can not belive the difference.

      Most 1 ton trucks come with the factory overload spring, which need to be removed for installation of RoadActive Suspension. Removing the overload allows proper fitment and ensures the system works as intended. The RAS® Mega-Duty kit will reduce squat and provide significant improvement vs the factory overload spring.

      I wonder as well, why they would send me a text message with links to these suggested procedures totalling over $10,000 without even the slightest hint of how they arrived at these being necessary.

      https://precisionlubrication.com/articles/oil-filter-efficiency/     For them it is a problem of $$$$ and compliance. To cover both they have to lie from the heart.    Government wants low waste oil numbers so the bar needs to be very low on contamination to met that requirement.  Consumer wants cheap maintenance (perceived cost). Again requiring a low bar.  OEM wants high margins at a cost effective warranty rate and lots of repeat customers. More low bar.  Filter manufacture wants the same thing the OEM wants. See the pattern?   Consumers are fickle and also want perfection requiring a HIGH bar. Inconsistent with all of the above. Consumers can be, when the put their minds to it, inquisitive, love winning arguments which requires some useful information to be available to support them. And this is where it gets sticky and the lies begin.    Information needs a solid well grounded point of reference if we are to compare in a useful way. There is a standard for this.  ISO 4548-12. This standard sets the particle size at a specific Beta ratio and darn few are faithful to its intent.    If they don't state the test method they change the particle size or the Beta ratio to hit a perceived favorable standard. They obscure the information in a way as to prevent direct comparisons leaving the consumer with one method. UOA's with an ISO 4406 test result. Pricey and not allot of labs willing to do the work. Lobby work happens everywhere, not just at the seat of government.
