Wow. Who torqued those down? I’d be checking all the others with a torque wrench because if one was over tightened to the point of almost breaking the bolt, maybe more are close to breaking.

Used Castrol Super Clean first then pressure washed it to get some of the big chunks and the oil and grease off.

A lot of wire brushes from Harbor Freight and a chipping hammer. (like for welding) It gets the big stuff off and gets into the small places that are hard to brush.

Rust-oleum Rust Dissolver gel.
Says leave on like 30 minutes.......I left it on all day. Put it on before work and spray it off when I got home with my electric pressure washer. Pour it into a bowl and use a paint brush to put it on. Used 4 bottles total I think. Leaves a white residue so after probably 5 applications and I was done with the gel I used super clean and pressure washed it off.

Corroseal Rust Converting Metal Primer.
Paint it on with a brush. It looks like milk going on then turns black. Let it cure. Used a little over a half of a gallon.

Rust-oleum Professional gloss black spray paint. Gloss because it cleans easier. Used about 5-6 cans.

After 1 application for 30 min to an hour. I could see this wasn't going anywhere fast.

During an application. Left this on for about 10-12 hours. Put it on thick.

Great job on that undercarriage. Some solid hours of effort right there.

Spent about 8 hours on the freeway over the last two days, with about 7k miles on the last oil change.
It looks like I got about 18MPG out on freeway with the cruise set to 75 mph.

That is why I spent many evening with rust remover, scrapers, wire brushes and grinder with a wire wheel under mine last summer. It was tough work but the results were worth the effort. This summer I am going to work on the inside of the frame, cleaning and then coating with some great product that I haven't decided on yet. The inside is hard to clean all the dirt and salt out of so I will probably have to make some special wands and tubes to spray and vacuum everything I can out.

This was after many hours of cleaning.

AC Delco?

AC Delco?

the first one was a cheap who knows brand, 25 bucks, says it all right there.

one i just bought was a delfi. 55 bucks. pretty sure im just gonna drop that new one in the hoe.

i got other issues holding the regal back. the sc belt is slipping like mad, one scan i make 10 psi, the next one 13 psi. but no matter what after the 1-2 shift boost drops to 3.5 or so psi. and it just falls on its face. so i also ordered up a belt wrap and ive got a much newer belt that will fit on that set up. the one i got on there now that fits is somewhat on the beat side, its been hung on the wall for years, and no parts stores local had one that would fit. so i was stuck using it for now. i never thought it could slip that bad.

on the bright side, this gen 5 blower sounds awesome, and ive been tuning it with out meth and low timing, and i put a larger pulley on the blower to help stop the slippage, and it seems faster already. at least first gear does. once its got more timing and meth spraying, and the 2.8 pulley back on. hey, hold my beer, watch this!!! lol

It'll bolt in with no mods? Need to change anything?

I’ll have to swap the reluctor wheel from a 58x to a 24x. Use a gen 3 crank sensor. Relocate the knock sensors from under intake to the each side of the block and extend the cam sensor to go to the timing cover. And the intake swap. I think that’s it

Lq4 or lq9 from a nbs truck or suv would be the easiest. Or a gen 4 from a nnbs and swap the things I mentioned above

I put in a new steering wheel bearing and intermediate steering shaft in my wife's 05 Tahoe, new LED headlights and new yellow fogs. I also put on some 20x9 275/55/20 knock off satin black Sierra wheels with some Nexen A/T a few weeks back with offset 31. After removing the shaft and bearing within 15 minutes. I knew something would go wrong...getting that bearing on was a royal PIA! Can't believe how different the truck drives now.

I am wondering why I had to trim some of the inner wheel well because of rubbing. Thought that 275 was a standard size upgrade and did a lot of research on this site. They also look awesome and drive great. They are very capable snow tires as well I drove through 15" of snow here in the NW like a champ.

I had 275/55’s on my welds and they only rubbed the left front fender liner in reverse. Probably rubbed going forward but the tire wasn’t catching the lip and I couldn’t hear it so I’m assuming it wasn’t

 

[ArcticYukon]

Ordered some foam-backed suede for the headliner and some matching non-foam backed for the dash and some trim pieces. Time to make this 'Hoe a little less ragged lookin'!
