Wow that’s a perfect example of one thing leads to another.

Wow that’s a perfect example of one thing leads to another.

took a bit of troubleshooting simply because my HID kit on there is my own aftermarket creation and the relay "buzzing" was a 1st. I had no idea the running lights were out initially.
I started troubleshooting at the relay and testing each part from the relay back and then I found it was creating high resistance when the truck was in drive (drl's) kicking on, which in my case turns the HID's on appearing to make the voltage drop to around 6.5v. but worked fine if the headlight switch was turned on.....
i knew the high load and low voltage was why the relay was buzzing, but no matter what I tried it didn't fix it.
so I was scratching my heading and telling my wife this makes no sense lol.
that's when I started swapping relays and replaced a relay in the wrong slot unwittingly, those all seemed good and nothing changed so I started checking fuses and found the blown running light fuse, but the running lights didn't work after replacing the fuse because the relay was not where it should be so I was really going WTF?
so I got the manual out and starting looking at the fuse box and saw my dumb butt had moved the relay to a "upfitter" slot, put the relay back where it belonged and everything worked again. ugh
at one point I thought maybe I had pinched a wire or something when I put the trim panel back on the rear hatch because there is crap ton of wires in the hatch but it is not "easy" to remove the trim cover and I had already broke one clip so I really didn't want to go down that rabbit hole, none of the wires had anything to do with the taillights except the hatch switch. glad I found my problem under the hood

Tried to find OEM replacement rear shocks for our PPV, since we're installing a Bell Tech drop kit in it next week. Several iterations of actually finding the P/N, then, I gave up because the shipping was almost as much as the freaking shocks.

Will probably 'spend local' instead.

So, I had 100 miles before my powertrain warranty expired (100k) and took my RST into service for what I felt may have been a transmission issue. Turns out to be only a broken motor mount. I’m in a 2024 Premier loaner with 400 miles until its ready. Winning!

Changed the oil after 3,253 miles, drained the catchcan (1.8 ounces after 2915 miles), got some goodies in the mail. HUD install hopefully will happen this Sunday.
Catchcan catchings:

Used a Fram Ultra Synthetic FE10575 instead of the Mobil 1 M1-212A, the Fram is HUGE comapred to the Mobil 1:

HUD stuff!

I got my Hellwig sway bar in a couple of days ago and I am pretty shocked at how improved the ride and handling is. I can't really say for sure that I ever got a fair shake with the Hotchkis but it WAS a positive improvement over my 10 year old stock bar and bushings at first at least. The hellwig in the front so far seems like a much stiffer bar (based on how heavy it is) if I had to guess and it really corners noticeably better now and just overall feels good.



I will freely admit that the Hotchkis bar is noticeably nicer for fit and finish. There was even a spot in the steel and powdercoat both right where the bushing would sit that was sharp and I sanded it smooth with a flap disc BUT Hellwig managed to pack the right brackets, bushings and hardware with my sway bar so that's a clear win for them over Hotchkis just for that. So far I've driven it pretty hard including a lot of harsher-than-necessary cornering both up and down grades and the bushings are still in place and the Yukon feels better than it ever has!
