I haven't seen much about replacing a front CV Axle on these trucks but completed this over the weekend on my 2016 Sierra Denali.  My truck has the Magneride and a 6" Fabtech lift and it's lived in Tx all it's life so there is 0 rust.

 

This is really straight forward with a couple of changes to the general procedure videos that are available online.  The 36mm axle nut is the biggest hurdle but an impact wrench worked wonders.  Once that is loose and the 6 15mm bolts on the diff are removed it should slide out...  Not so fast.  Most of the videos I saw had the strut removed and I wasn't doing that.  I removed the swaybar endlink and the rear side lower strut bolt and threaded clip for that bolt and was able to then slide the CV axle towards the diff, pivot it 90 degrees then forward out the front of the suspension under the bumper.  The hub side joint will slide between the LCA and the swaybar when it's close to the diff.  

 

Installation is the reverse but the only way to get it in is the same way it came out.  Once the axle side is in and through the hub add the washer and nut to only hold in place.  Install the 6 15mm bolts to the flange for the diff side and tighten.  Reinstall the strut bolt that was removed and the sway bar end link.  I then put the wheel on, lowered, then tightened the axle nut.

 

Now I have to replace 2 lug bolts after screwing the threads trying to remove the axle nut w/o the impact wrench but that's another day...  all 6 nuts are installed but 2 are difficult to turn.

      Cold start Miss, oil in cylinder

      By asilverblazer · Posted

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
