2008 Yukon Denali, 135k miles, part 2!!

[tgui]

Did you change it yourself or have it professionally done? I've always wondered how difficult these are to change on a full size GM truck

I had it done at the same shop that caused my brake problems. I think you can brace the engine on the oil pan then replace the mount.

I'm working on making my idle smoother. I did 3 things.

- reprogrammed the pcm to idle a higher at 625 rpm

- cleaned maf. Use dedicated maf cleaner.

- cleaned throttle body. Use dedicated cleaner for this as some destroy coatings and the plastic.

Holy moly this is dirty

After cleaning

The pcm takes time to relearn the throttle body after it's disconnected. Shifts are weird and throttle response sucked. I did a few drives on the highway and it's better now.

Overall the Yukon idles nicer. I'll post later if this changes. It's nice that it idles like a luxury (sort of) vehicle should.

Ohh and I read some idle lumpiness is inherent to the engine design. The 6.2 and other engines have heads that flow so well it's hard to get a super controlled volume of air at idle.

I need to clean the TB and MAF on my Caddy now! Damn you and your inspirational attention to detail!

Ha! This was easy too. Like 30min.

I did a fairly quick polish. Meguiars 105 then 205 then Klasse sealant. The dealer tried to clean it but left tons of swirls. 3 hours work, not too bad. The porter cable random orbital makes things faster.

Btw klasse is awesome.

It rained pretty much right after I finished. I couldn't get a good shot.

I did get a good close up of beading.

 

[Fosscore]

Nice beads. Like the Klasse and it leaves a good coating.

Don't forget the Klasse All-In-One, or AIO.

Terrific for adding depth and clarity, especially on metallic paint. Makes the metallic flecks appear almost three-dimensional or holographic.

Finally my front end is done. I had been close but got the wrong drivers hub. It was for a gmt800. It fit but the abs connector didn't work. I was outside of the return window so had to eat $130.

All done.
- brake lines
- pads
- calipers
- rotors (again)
- end links
- wheel hub

She now feels reliable.

Now I start looking at a LSA supercharger.... or a turbo. I'm undecided.

I have that aio too. It might be my equipment but the aio leaves a haze. I prefer to polish the shit out of the paint and is the other klasse without polish in it.

Looking good man! What's the make and part number of that GMT800 hub? If I can use it on my wife's 2006 Escalade I'll take it off your hands so you aren't out that money...

I cut the connector but can solder it back on. $50, you pay shipping and it's yours. Or make a deal. Whatever

Sounds good to me sir! How far back did you cut the pigtail? Would it be possible to just repin the connnector? You can PM me your paypal info and I'll send you the funds...

My dash is cracked. I have no interest in removing the dash. I took the lazy way and got a dash cover like my grandparents use to do. The first one I got was the wrong color.

The next one I got had no hole for the center speaker. My bad. I'm too lazy to return again so just cut the hole myself. If I can build a trans I can handle some cutting!

It fits and looks better than cracks.

Beyond that I have my engine tune down and am fixing some things in my trans tune. She runs like a ***** ape!

Next in the plans, LSA blower. I've had a turbo car, time for a supercharger. This is my goal!

Not mine obviously....

Blower = optimum joy.

Have you sourced all your parts yet? I have a spreadsheet left over from all my posts with cost L. If you want I'll send it to you.

Please for the love of God send that to me!

I will get on my PC later tonight and send it to you!!

Nice!

Before the supercharger I wanted to finish sound and the interior. I picked up a sub kit that fits between the captains chairs. It has a 12 inch "square" kicker sub and a is a bit taller than in the pics.

It arrives in a couple weeks!
