My '99 Trans Am's entire rear axle isn't painted, coated, waxed, or otherwise protected at all.

 

Just sayin'

Not sure what your sayin' or how exactly it pertains to the thread? Is it rusting? if so, is it due to no protection? If not, our trucks are and that is our point.

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

Heck ya it's rusty. It was covered from hub to hub while sitting on the lot. My point is, GM didn't even care to attempt any corrosion protection on that vehicle. Our trucks are pretty much entirely covered in something. Good or bad. Granted, the TA didn't cost $50k. My axle still works.

My frame was in the same boat. Its currently receiving the TSB fix for the rusty frame problem. My 2004 silverado that I sold before buying the 2014 didn't look like this until 3-4 years.

They are going to be "fixing" applying the TSB resolution steps to it shortly.

I know this is like the 4th thread I've responded to on this issue but it irks me so much I can't let it go. I'm in the same boat as you guys. I'm getting the TSB repair done next week but I don't have faith it will work. Something happened with the frame prepping process before these things were dipped which is why the garbage wax coating is peeling so easily. I've only had my 2014 truck for 2 months and it looks worse than my 2007 silverado did after 7 years. Bottom line is a frame shouldn't be rusting this early. Ford doesn't. Toyota doesn't. Nissan doesn't. And Dodge doesn't. So I dont like being told this is normal and acceptable for a Chevy. It's un acceptable and Chevy needs to improve their design. They tout this as being the most corrosive resistant silverado ever which is true for the body, but they did nothing to improve the frame. Anyway I'll keep everyone posted on how my repair goes as well.

What was your build date, where was your truck built.

Just wondering date built?

Mine was built September 2013 in Mexico.

I was at the dealer yesterday and I looked at 2 new trucks that just came in and now they have a clear like glaze sprayed on the frame and rear axle. Maybe they're addressing it at the factory now?

Wow, that is the worst rust on a 2014 I have seen to date. Unfortunately, all they will do is spray on 3m rubberized undercoating which will last a few months. This is what we did when I worked at a dealership back in the day.

I have to get some pics up..they just fixed the bad areas..they did follow the tsb to a tee for those areas.They didnt use a spray, they used a brush. They used the products listed in the TSB. Took them 72 hours as they had to account for dry time in between coats.

I don't think I got the TSB fix on mine. Apparently my VIN number wasn't one of the ones in the recall. They cleaned the rust and sprayed the spots with a black coating I think by 3M but it was an overnight fix. Not the 72 hour job you guys are describing or the thick painted on product. Anyway they missed some of the rust spots so we agreed they would fix it all when I bring it in for my next oil change to cut down on the number of trips to the dealer. I'll see how the current repairs hold up in the mean time.

 

I personally don't care much about the look of the rust, it's a structural issue for me. I just want to know the frame will last 10 years and not break in half.

The proper stuff to use when touching up the frames on these trucks is in an aerosol can bearing GM part number 12346501. It is a match to the color, texture and overall appearance of the factory applied coating. I touched up a couple of small spots on my 2013 frame and it looks spot on.

Heres the page I posted the TSB on with all the info> http://www.gm-trucks.com/forums/topic/158444-factory-undercoating-is-peeling-off/page-2

 

But in short they are "recommended" to use the following products:

  • Using Lloyd’s Pure Prep™ Metal Surface Preparation P/N 25418 (10 fluid ounce bottle), or equivalent, saturate a towel or Scotch-Brite™ (3M) pad with the pre-diluted solution and scrub the area well, rendering a foaming of the Pure Prep.™
  • Apply a light flash-coat of Lloyds Kryptonite Metal Treatment P/N 36502 Life Long Rust Protection (14 ounce aerosol), or equivalent, to all rusted and bare areas of the frame where the wax coating was removed. This first coat should flash in approximately 3-5 minutes.
  • We suggest top coating the Lloyds Kryptonite with Daubert Nox-Rust® P/N X-121B “One Coat Rust Preventative Coating” (aerosol), or equivalent.

    Note: As shown in the graphic below, besides adding a corrosion resistant layer, it dries to firm, wax-like film which will more closely resemble the appearance of the unrepaired areas of the frame.

With that said, they can use aerosol or equivalent, which they can use a brush type system to prevent it going everywhere and looking on mine, you can see brush strokes, not spray (they may have used spray up until the final thick heavy coat).

      OCI, not when but why?

      By Grumpy Bear · Posted

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case."

      Transmission jumping out of gear while driving.

      By JimCost2014 · Posted

      Probably a one and done post, but do you have a CEL on the dash? Was having issues with my transmission, fortunately only a week, and it turned out to be the transmission harness. Valve body was in good shape, so new harness with all the sensors attached, new fluid, and filter. Seems to have worked so far?

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.

      Weird click noise when revving my truck?

      By JimmyB4 · Posted

      Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!! RIP - Chevy 5.3 IMG_6043.mov

      By KARNUT · Posted

      We’ll have to agree to disagree. I didn’t experience or know anyone who had a decent car after 100K miles in the 60s through the 80s that were daily commuter vehicles. Unless they were collector vehicles. Of course things cost more due to inflation. But we also make more money. The biggest money drains these days are things people think they need today versus what we require back in the day. Like cell phones and internet as examples. Another example is where you live. Cost of living varies from state to state. I would need twice the money to live in NJ vs Texas in retirement. The car you recently purchased was less than my first car with inflation at 3000$ in 1973. I didn’t have air, electric windows, cruise etc. Purchasing power is equivalent, you just have to do the research.
