I looked at the video you posted and he sure made it look easy. That sucks it didn’t work. I wonder how many others had the same issue as you did. I sure hope they don’t give you any crap about returning it.

It should have worked but the allowable tolerance is off or the housing has some kind of wear that makes it stick, probably would have to replace the housing and the cylinder at the same time maybe. The old cylinder was only a tiny bit sticky with my original key which is worn the new key and little bit of grease seems to be working fine

Circled back around to install part of the steering rack stiffening kit. This metal forked wedge thing required the removal of the front diff, so yeah that was fun to yank out and shove back up by myself laying on the driveway. At least the stiffener went in with no drama. I forgot to order a new clamp for the passenger side steering rack boot, because I don't think I can get the current one off with out destroying it, and it needs to come off to remove the rubber bushing.

While I was tinkering around I swapped the AP stainless muffler back in on. The MBRP muffler sounds great from the outside, but drones too much in the cabin. I'm still thinking about grabbing one of those QW mufflers and playing with that to see if it actually kills the drone.

That clamp can come off and be re-used! Just stretch out the clamp tab a little with a mini screwdriver and it will pop apart with some massaging.

I used a mini end cutting pliers like this one to tighten it back up.

Is the bushing stiffener noticeable?

I tried my hardest with picks and a long thin flathead, but the guts of that clamp are between the rack tube and the frame, and I just can't seem to get it unclasped.

I just took it for a short drive to listen to the exhaust and didn't really test out the steering. To be honest, my bushings are probably fine as-is, I just wanted to upgrade the experience.

Looks good. Hope that flexpipe stays sealed for years and years.

Did they just weld the factory Walker clamp to the exhaust pipe, to the right of the v-band? That's kind of ingenious.
Factory clamp was cut out and this replaced it so the y pipe can still removed if needed
Not sure what the fresh piece is he added I walked over to the store while he was doing that part, the old piece was rusty looking

Well this was a fail almost a really bad fail, coded the new cylinder did it right, lubed it, went out and put the cylinder in and nada/locked up, couldn't turn the key, so I was like motherf-ker, jiggled and jiggled and jiggled and finally it turned and then I thought ok maybe it was just virgin and sticky, turned it back and ****** it stuck again, finally managed to get it to turn again pulled it out and went back and doubled checked I had it right (I did), so I figured wth I'll just use the extra new pins and insert those in the old cylinder so it's at least something new, and guess what? Yep stuck again.....so old cylinder and pins back in, works fine. New key works so hopefully I can return this thing and get my $80 back, maybe the receiver part is worn as well and it just needs a little file work but f- it im good

Hey Wes, What did you choose for the blackish Chrome tips? Been on again and off again with wanting to do that to mine. Don't chrome since my truck is basically black or white and completely void of chrome.
it was just some that the muffler shop had on display in there office, no particular brand that i am aware of, I put the same one's on the wife's truck a while ago and they still look nice so I figured I would change mine while I was there. Next time I am over that way I will ask them if they are any particular brand.

apparently they made me a whistle, have to see if maybe it needs a wire wheel inside the weld or something, maybe a shard is sticking up, :shrug:
shows up at about 4500rpm+ under a load, doesn't appear to be speed related/wind
find out tomorrow

Turbo sound effect?
