Chopped up and rearranged the cat back.
Previously the resonator was just tacked on the end of the tailpipe just so I could try to see how much of a difference it really made.

So this afternoon I ended up basically redoing the whole Cat-Back. Left the v band on the cat, and the flex pipe coming off of that, then put the 3.5" resonator, then the 4" muffler exit, to the 3.5" inlet, then another v band and over the axle section.
Pretty sure it cut down on drone but I won't really know until I put a good bit of weight in it again so it can actually load up for long periods of time. The resonance previously was really bad when loaded, but hardly noticeable when empty.
Glad I was able to fit the resonator and muffler between the crossmember and the rear axle so I still only have a 3.5" section of pipe coming out of the back and no ugly resonator hanging down.
The only thing I really need to finish is the tip. I through the one that I made previously back on it for the time being so I don't melt the bumper. But it sticks out way too far, and I'm thinking I'll try to slash cut it sort of like factory.

Detailed inside an out only took an hour, and I do this every 3 days
Especially when you have black/black + kids = nasty (finger prints and smudges on doors outside and windows in and out
Crumbs on carpet “leaf’s, dirt”)
I’m just OCD about dirty vehicles

Edit I’m in the wrong area lol
I share your palsy. I like to have our cars looking like they just rolled off the line. Drove the family to Cape May New Jersey this weekend, through a torrential rain storm, and then spent an hour wiping it down and detailing everything after I got here.

I do the same on occasion. Wife says I am hump-ing my truck and should have named it “Mistress”.
Whatever, Karen. :chillpill:

Finally Replaced the front struts with all new parts except for springs and top strut mount. I've had the parts sitting in the garage for 3 months, lol.

That spring compressor kit I bought earlier this year from a link a member posted on here worked like a champ after spending a few minutes figuring out how to use it, lol.

Then after resetting the ALC trims I washed it. 20210925_190329.jpg

and i totally used the leaf blower to blow off the layer of dust it has on it right now.

:challenge:


I made some little elbows out of some -6 an tubing i have, eventually they will be my radiator trans cooler bypass!


Ended up deciding to finally fix the bathtub faucets since the hot side has had a slow leak for a few months now...

that turned into a massive pita.
guy helping me find parts was lazy, i ended up getting just the seats and the seat seals.
that turned into some leaking due to the hardwater bs.
so some crossbuffs (cylinder head/intake porting tools ftw) to clean the seal surfaces and some Neosporin as a o-ring grease and i have it fixed! :jester:

then the inside water main valve started leaking.
at first a slow drip.
usually i just use pliers to really open it to stop the leaking.
not this time!

more i dicked with it, the worst it got.
Youtube to learn how to use the complex lookin curb side water valve, luckily i had a tool for my secondary water that worked perfectly!

then then time to figure out how the fk to seal the valve.
nearly looked like i needed to cut copper and solder a new valve in...

Little cap that goes over the shaft :boobs:,had some super deteriorated looking seal stuff in there.
picked that crap out for like 20min to figure out if i can reseal it.

ended up with am answer of :poop:

so i took one of the rubber o-rings from my random little amazon kit, found one that sorta worked.
Lubed that ***** up and tossed it in there.
cranked the cap down, turned on the water main and no more leak!!!

w00t w00t!

today I had the plan of to replace the kitchen facet, but this took all fkn day.


Now i have a mt dew, and some rum.
Mix it together, and I call it a dew-jito (mojito but with mt dew).
a recipe i learned from a coworker years ago. :cool:

Did a quick and dirty wide band install.
I'll figure out where to put it and clean it up later.

Rearrange the cat back, but the resonator right off of the cat (after a flex pipe), then the muffler and over the axle. Got all the hangers on, just need to figure out how I want to finish off the tip.

We didn’t but now that I know about it, we’ll pay a visit when we go back. Could end up being an annual event for us. We had a helluva good time on the beach and in the water. Had beautiful weather for the drive home today.
I love Cape May. I haven't been there for a few years.

Today I washed, clay bar, and then waxed my 2009 Tahoe. And then finally installed my Z71 interior trim and got rid of the woodgrain. Now what to do with the woodgrain kit?

Getting rid of that stupid forward bin with the doors is one of the best mods I've done. It's hard to tell from the pics...what are the replacement trim pieces? Are they just painted black?

Since I purchased this, it has had a rattle in the steering column when I hit a bump with the front end. Partly that’s a worn universal where the column meets the rack, and I just haven’t gotten around to it yet.
Today I also discovered at the passenger end of the rack, the rubber bushing that isolates the rack & pinion from the mounting bracket is loose, and I can move the rack slightly in the bushing. So, is that bushing a serviceable part? Or do I have to replace the entire rack?

The bushing is captive in the area circled below. Like a rubber donut that circles the rack and in turn is enclosed by the mounting bracket with the 2 bolts.

I also have a clunk in the front when I hit certain bumps, thought maybe the rack bushings or something. Haven't looked hard, but also no obvious culprits...yet.

It's replaceable. I have this one I bought from Febest, waiting to go in when I have some time:
