Box Wheel Well Liner Question

Swapping the back up lights today & came across this:

 

2017%20Silverado%20HD%20Tail%20Light%20O

 

This is after almost 3 months of service & about 2,000 miles (the LH side was the same). I seem to recall the GMT900s having a 'ribbed' plastic part between the wheel well & the rear of the box side (I could be wrong though). If this part was present, was it to prevent road spray from spreading?

 

My brother has a '16 Sierra HD w/ the liners. The nephew is going to pull 1 of the taillights & see what kind of mess is behind it.

 

If the liner doesn't make a difference, I'll just make a point of pulling the tail lights in the spring & cleaning the sand & salt off.

 

In the past I was well aware of making sure to wash the upper portion of the wheel opening where the 'wheel house' stamping & outer panel are spot welded together.

IIRC - the 25HD's with the Snow Plow option includes the wheel well liners - though (dealer installed)

That's the first I've heard of that content for the VYU option.

I will be removing the tail lights to check this as well. I have the liners and hope that they help with the salt and dirt up there. May need to be looking into some extensions behind the tires.

Do you guys mean the felt wheel well liner or is there another part that I don't know about?

On my 2011 25HD the rear wheel liners covered the entire rear frame behind the tires, the 2015 only cover about 1/2 the frame ...

Not sure of the mat'l, but some trim levels (depending on whether it's a GMC or Chev) have a moulded 'liner' that is installed in the rear wheel openings.

That must be the part that I'm thinking of that was on my '11 as well.

Looking today and there are already 4 holes pierced in the 'inner' stamping.

 

2017%20LH%20Rear%20Wheel%20Opening%20-%2

 

(1 of the holes isn't visible)

 

I'm thinking once the warmer weather arrives, I might do some do some 'cardboard assisted design' & make up some mud guards like I did on my Ranger:

 

Ranger%20RH%20Mud%20Guard%20-%20RESIZED_

 

(RH side looking forward)

These mudguards were made from truck mudflap mat'l.

 

Another note, is the 'slop' is just the crap off the highways up here from salting & sanding operations, no mudding involved.

I finally had time to look in the tail light openings, wasn't all that bad just sand. 4500kms. I found little spots on both sides sides of what seemed like paint wear off. I washed out the voids and sprayed Rust Check on the spots before putting the tail lights back on.

I found genuine GM wheel well liners for my 2016 GMC 2500HD. Shipping isnt cheap, so I called my dealer. I can buy them for about $120 for the pair. These are the "carpeted" style just like the front wheel wells. No hardware is included. The truck is already pre-drilled for the attaching parts. You can find those on ebay if you do some digging. You will need some square nuts that fit into the truck and then bolts to thread into those nuts. Gm wants alot for the hardware...I think there are about 16 attaching points on each side of the vehicle. I believe they want $5 for each piece. I found all of the hardware for around $30 on ebay or amazon.

 

 

This you tube video gives alot of info ...

      OCI, not when but why?

      By Atlas · Posted

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.

      I apologize, I missed this post, at risk of going off CURRENT TOPIC.   I'm not saying it is BS, I'm questioning how much information is being held back. GM is NOT going to spell out exactly every parameter in the algorithm. Liability, intellectual property, etc.    I'm not naive enough to believe that it is as simple as revolutions, coolant temperature, miles, time; are you?    I don't do irrational either, and boiling the OLM down to four simple values that I could code in an afternoon (I'm not a coder) is irrational - unless it suits your agenda to ignore it.

      Chris 21 I appreciate your constructive response. !!  😉😉😉   The 6.6 is gas.  Correct me if I’m wrong but by recalibrating the speedo you’re correcting the shift points of the transmission on these trucks.?.

      That is a huge misconception.     Bigger does not always equal safer.  Modifying does not make it safer either, with exceptions.   Think of this.  Your truck in stock form is capable of emergency maneuvers, proper stopping distances, its handling is designed around the factory wheel/tire packages, etc.   37s and a lift?  Now you've affected your braking distances, handling and ride control.  You've raised your center of gravity higher.  Your front visibility is now obstructed more than stock, same for your rear.  Does it look cooler?  Yes.  Does it now work as good as it did from factory on road?  NO.       As for my mention of exceptions?  Say you had a sedan or crossover.  They typically come with all season tires.  If you swap out for a performance all season or a summer tire, you improve your car by lowering its stopping distance (better braking because of traction) and improve the handling (regular and emergency) of the vehicle.  That is an actually improving modification.  My old 2019 LD 1500, I ran UHP all season tires on 20in wheels in a factory offered size.  It improved all aspects of how it drove over the Duratracs it came with from the factory in the stock 18" tire.
