just grab a denso from the local auto parts, that's what will come in a oem box anyway.
bank 2 is easy
Which one is it on the y pipe? I cleared the code yesterday and it hasn't come back yet. I was hoping it had nothing to do with the tune. It's running fine.

When the guy installed the motor a year ago he said some white/powdery dust came out of the converter assembly when they put it on the ground on end. He said that means it's on its way out?

I'm not to educated on these parts.

P1153 is Bank 2 Sensor 1, so passenger side upstream (between the engine and cat.), and IIRC it's easy to access through the wheel-well if you pull out the fender-liner, although you can get them from underneath with a flexhead ratchet and an O2 sensor socket, like this:

Don't bother with this style, it doesn't provide enough clearance to make it a simple job.

Get a pick-tool or bend a tiny flat-head screwdriver to undo the O2-sensor harness tucked up on the frame, near the body-mount.

You can soak the O2 sensor threads in juice while the exhaust is hot, and it'll suck into the threads, or when the exhaust is cold, you can hit the bung with a torch to expand them. I never had an issue getting my O2 sensors out, and we use more salt for a longer period, than you guys. I think the combo of decent-quality stainless in the y-pipe, and the extreme heat quickly evaporating the slush off the pipes help keep them from being too funky. ymmv

passenger side before the cat, you can get it from under the truck. back it up on some ramps since you have it lowered, grab a 02 sensor socket and use a ratchet with the tilting head. easy-peasy. unless you have room to drive on the ramps going forward, when I had the silverado lowered I had to backup on ramps

Today I broke my interior door handle and just about ripped the door panel off.
All because my hinge bushing was so warn that if my door is opened all the way it won't shut. I had to use a large screwdriver to compress the spring to close it.

So what hinge bushing are you guys using? Stopped in at one of my local auto parts stores and they wanted 60 beans for a new one. I was curious if they sold just the bushing. Anyone know?

There's a few roller kits forsure.
I'll look, but I know @Doubeleive knows of some.

Here's one someone posted not long ago..

Dorman here..

In the meantime, pop the spring out, you'll have to pop it out to do the roller anyway.
I haven't a clue, my advice is have a body shop replace it and call it a day, because those guys know how to align the door correctly

Free travel mod. This is on my list to do this winter. I'm not very good with a side grinder, and don't have a plasma cutter. Has anyone tried an oscillating tool with a bimetal blade to do this? That gas tank is awfully close!
That sounds like a friggen nightmare to me.
