Unless there is something unique with the GM Nutsert you can do them without a tool. Find a bolt that matches the threads....usually 2.5" X 1/4" and washer a and nut. Thread the nut to the top of the bolt add washer and start the bolt in the nutsert. Place in hole and tighten until nutsert is pulled tight. The nut is sometimes necessary to help hold in place while you remove bolt. You can also hold the bolt with one wrench and finish tightening with the nut. It's best to keep from spinning the nutsert in the hole.

Edit...spell check turned nutsert into nursery.

Interesting for sure. I followed the instructions that came with them. Basically had to step up the hole size with 3 different bits. Once that was done, I put the "nutsert" in and used the supplied screws that came with the kit. Once it got a few threads in it, it expanded and gripped the rest of the metal around it and the screw tightened as normal. I was concerned at first because I could rotate the "nutsert" in the hole that was drilled. So far, so good. If something were to happen, I'd use self tapping screws for them all and not drill anything if possible.

 

Anyone tried doing it that way?

I think what you described will work, but perhaps will not be as snug as when using the proper nutsert tool which makes the install without any spinning of the bolt, i.e, you can make it that much tighter if the female end isn't spinning free.

The female portion only spun by hand. Once the bolt was in it, it spread and snugged up well. Torqued down good, too. Still like the self-tapping idea next time! :flag:

Lots of great info. My flaps came in so I will watch some videos on this process and try some of your suggestions. Won't be installing them till this weekend, but I'll keep you posted on what worked for me as well. Thanks y'all.

Here's a video of the trick he's talking about:

 

I tried this trick and got it to work on 3 of the 4 rivet nuts. I think my downfall was that the metric bolts I bought to use weren't hardened enough, but the store only had one grade of bolt for the metric sizes. If I could start from scratch I would just find some black self-tapping screws and skip the inserts. I don't know why that wouldn't be secure enough. The back ones were cake even with removing the tires.

 

Early in this thread I think someone asked if the guards clear steps/running boards. I have Luverne nerf bars on my truck and the splash guards just clear them, but they make it really hard to drill the hole and insert the self-tapping screw on the bottom of the splash guard. If you're going to put both on your truck, put the guards on first.

I got my huskey mud flaps today and got them installed. They fit and look good. I did have to drill one hole for the front and three for the back per side. I will get pics tomorrow.

I had my OEM color matched installed yesterday. I was going to do it myself, but decided that the $80 install fee was worth it.

 

I have the OEM 22" wheels, there's no rubbing and IMO look really good. I'll try and shoot some pics, later this morning.

I don't think I got anything special as far as pricing goes. Service manger told me that it was a half hour for the front and half for the back.

 

I turned the vehicle in at 0715 yesterday morning and at 0820 I was called that it was ready for pickup. I also had the tires rotated, and the AFM update loaded.

Word of advice guys! If you have the guards installed at the dealership, you better make sure that their techs understand that they need to read the directions and leave all of the fender spats on the truck. The idiot that installed mine pulled all of them off and threw them away even though you can obviously tell that the guards are molded to fit around the factory pieces. Now, I have gaps where they should be. My coworker, the service manager is not gonna be too happy when I go in next week and order all four of my spats from GM and another complete set of guards for front and rear since these are now ruined and must be replaced. His wonder boy tech that failed to read the instuctions just cost him a nice little wad of cash and I am gonna fight for my installation labor to be refunded too. I will replace everything and do it myself this time, I just hope he didn't screw up anything that I can't see since the guards are covering the areas where the spats were. I realized after reading the GM service manual that all four factory pieces have retainers that clip into the body and must be released to be removed, so I hope this ignoramous didn't snatch them off and damage the body panels and paint. Now I know how a lot of you "regular" customers feel about dealers since it even happens to me and I work at one! LOL

Sorry to hear that, I'd be pissed! No gaps on mine, I always request that my friend (who's a mechanic) installs everything I bring in. He's a real mechanic, not a parts changer. I feel confident he did what was supposed to be done.

 

Hope it all works out for you!

Just installed mine this weekend and man do they look good! I ended up not using the nutserts at all. Like others said, using self tapping screws made everything a lot easier. In fact, when reading the directions it says that the vertical screws at the bottom are "self tapping" so I'm confident they're fine. Thanks to everyone for your help and suggestions.

My truck came with the "heavy duty" mud guards. And at first I wasn't thrilled to see them on there. (My dealer acquired my truck from a different dealer, everything is spec'd correctly). But after driving with them for a couple months. They grew on me.

      Post your UOA, (used oil analysis) here

      By Black02Silverado · Posted

      Here's the second UOA on my 22 Wrangler with the Ecodiesel. This has 5k miles on AMSOIL Signature Series DEO 5w-40. The first one was dealer installed oil, no clue what it was, the second is what AMSOIL recommended, European FS 5w-40, Most of the Ecodiesel world is showing great results using the European MS 5w-40, I figured I would see how the DEO works. This is using an Ecoguard oil filter. It's my understanding this engine likes to shed aluminum.  We will see. So far I don't think this is too bad.

      Disable DRL's

      By revmanii · Posted

      I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
