I've decided to do a career change which means I gave up a company truck and will now get paid to use my own vehicle. My 2008 Denali will go from beater/overlanding/extra vehicle to a daily driver now. Other than it being old-man gold in color, I really enjoy it. So, I decided to tackle some basic items for longevity, better ride, and maybe some more mpg's.
First: put in all 4 oxygen sensors (no codes ever present) based on other's input here since it has 183K on the originals. That made a difference in the test drive - positive win! I then replaced the MAP sensor gasket and threw in a new Delphi MAF. I've had a somewhat rough idle (feels like a cammed motor occasionally) that I felt could be addressed. The MAF sensor helped smooth that out and the overall driving characteristics seem more refined. I now have spare parts for the MURPHY KIT that I know are good .
Second I bought GM OE lower control arms from Rock Auto (bend over without lube....). Since the originals lasted 183k with only minimal play on either side, I figured just go for it and then it's done. I also bought new sway bar links and bushings (another recommendation from here).
This is where the rust free REALLY was nice. All the hardware came apart easily (axle shaft, LCA bolts, struts, etc). It was so nice to just pull stuff apart, and put it back together. No torch needed!. Even the O2 sensors popped right out without any fuss.
Now that it's back together and road tested, it feels like a new truck! The ride is so smooth and quiet now over bumps in the road. What a difference some bushings make. To be honest, replacing sway bar bushings has never been on my radar, but is now for sure. What a simple way to improve the ride.
Along with new vented rotors and pads all the way around, she's ready to hit the road. Next week I'm hoping to replace the RMS and finally be able to park on concrete like a normal person....LOL
