It started as an oil change and annual inspection. Then I probably need the coolant replaced.

so now the front and rear differentials and tcase are serviced. Coolant replaced. fuel injectors cleaned. And the front sway bar bushings got scared and ran away sometime in the last couple of months.

with the new brakes when I bought it and the transmission fluid service a few months ago, the rig ought to have a pretty good baseline for service.

First oil change on my wife's new-to-her Suburban. Catch can was surprisingly full and had crap that had wet almost peanut butter like consistency at the bottom. The can is much smaller than the Elite Engineering can I had in the old one, so I need to remember to check it a bit more often. All that crap has collected in about 3500 miles.

Also installed a Fumoto valve to make future oil changes a breeze.signal-2023-05-07-125908_002.jpegsignal-2023-05-07-125908_003.jpegsignal-2023-05-07-132036_002.jpegsignal-2023-05-07-132036_003.jpeg

Finally also got around to do the data logging for my DiabLew tune on Sunday. Lew did great job turning the files around in less than 24 hours, so loaded them yesterday.

Such a big difference in the way the truck behaves! Money well spent once again.
