84793824 should be trailboss axles.

yeah that's the number I have, although on the diagram it is shown as separate parts but I assume they arrive assembled and ready to install right? I ordered the boot by itself, I'm gonna try and see if I can just install that and if not just buy the whole axle. Any idea if you can take the bottom joint off so the old boot can slide off and the new one on?

The axles are assembled if you buy the whole axle and ready to install.  I'm not sure if you can take it apart where they boot will slide off but I would think so.  I think replacing the axle would be a lot easier and cleaner even though it cost a little more but may be worth it.

You can replace the boot, just make sure you have the correct tools for fastening the steel clamps around the boot properly.  If not done 100% correct, it will leak like a torn boot.  I know it's not cheaper and I have no clue what your budgets are, but it's far easier and cleaner just to purchase a new CV and install it.  When done this way, you can keep the original as an emergency backup if you ever break one on a trail or back road.  Good luck!

Thanks everyone, yeah I just ordered the whole axle, I think its gonna be much easier and since I had already ordered the boot I’m just gonna do as you said and keep it as an extra one. I’ll let you guys know how the install went.

There will be no difference in getting the shaft into place.  The additional length of the longer CV shaft will be hidden inside the cup.

It was a direct replacement so no issues. Very easy to just pop it out and replace them.

I was able to remove the old CV axle and replace it by just removing the upper control arm. Hope this helps.

What did it sound like when they where going bad? I have a loose or bumping noise at lower speed usually not so much when I get on the highway

Bad CV's will usually pop or clunk when turning.  You may observe a noticeable clunk when engaging 4WD or a popping/clunking noise when traversing obstacles in 4WD.

I finished the other CV Axle last night.  Feels good to have this project complete and while I was in there I cleaned up all the grease from the boots on the other axles.   When I rolled under to put the skid plate back on I looked at the angles of the axles and to me they do not look that bad so I am wondering when the dealer had it if they just looked at the angle while the truck was on the lift because the whole front suspension is drooping so the angle looks really bad on the axles but on the ground I think they are fine.

What is the actual part number for the longer Trailboss CV axle assemblies ???

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w
