Make sure to do coil boots and torque the plugs to 15ft/lbs. I fought a misfire and pinging on an Expedition, the "senior tech" had just done a tune up two weeks ago, so the shop owner didn't want me wasting time looking at the plugs. Well, six hours of diagnosing chasing everything else, I pulled a coil and found melty boots with loose plugs.

No pics but today I did spark plugs in everyones favorite 5.4 F*rd...... hopefully stupid misfire goes away
Oh yes. I did that this last summer. Had to extract 4 plugs that broke off. The extraction tool really is a life saver. Still had misfiring on two cylinder (with new coils) so I checked the part number on my new plugs. They were not the updated part number so I pulled them all back out and put in the updated part number. Good to go.

I found before I did this that 3 coils have been replaced, 5 were original. I replaced the other 5 today. I'm a little worried the plugs weren't the cause. The ones I pulled out all looked in pretty good shape and gapped properly..... all were the same motorcraft plugs I replaced them with. I had already tried swapping the coil on the cylinder that was giving me fits and it threw the code again which is why I decided to do plugs, because it also gave me a P0300. I haven't driven it since finishing it, and it would only do it before after "long" periods of time on the freeway. Pretty sure something still isn't right because it seems to be missing still, I haven't brought it up to temp yet though.

Saturday my son and I cut the spare tire well out of his WJ floor.




We then cut his tank skid. We removed a 6.5" section from it to tuck the tank up tight to the underside of the body.

We then cut a 5”x2.75” hole through the left rear frame rail in which to run the fuel fill tube and a couple of vent lines through. I’ve seen people cut a hole in the floor and build a box to house the fill tube inside the rear cargo area but I don’t think that looks like a very clean mod so we opted to keep everything outside and under the Jeep undetected. I also saw one guy who cut a 2" hole with a hole saw through the frame section and used a piece of exhaust tubing which looked like a nice job but it didn't account for the other couple of hoses that needed to reach either the fuel fill or the charcoal canister. This will allow adequate space for all of the hoses and not crowd them.

Hole cut in the inside rail.


After boxing with 3/16" plate, fully welded and painted.


Outside of frame rail, behind the charcoal canister.


I don’t have any pics of the skid once it was trimmed and welded for some reason so I’ll have to get s couple tonight.

Yesterday after we returned from breakfast I had a couple of things I wanted to do in the shop.

I have grown tired of chasing my cutoff disks around the drawer so I machined a few aluminum standoffs and secured them in the drawer as pegs to store a few of my more commonly used cutoff and grinding disks.








Done. That should keep things in place. I’ve wanted to do that for several months now but either didn’t have the time or I’d forget until I grabbed another cutoff disk then I would remember.


Later in the day our winter storm settled in.

I give you the SmokeMaster 5000 XH

So after making 12 lbs of Jalapeno/Cheddar sausage I needed a way to smoke it at a pretty cool temp so off I went to the garage to cobble together a ventury style cold smoke generator.

After pondering for a while at Home Depot I returned with these

118333

The 1/4" pipe with the brass do-dads on the ends is the ventury jet and the 1/4" pipe gets mounted through a hole drilled in the 1" cap.
I TIG brazed it since the cap is made of cast or low-grade junk.

118334

The 1" pipe get a slot cut into it to draw in smoke from the wood chips when the jet is pushing air through the ventury.
Here is the assembly

118335

Now on to turning some 1/8" plate into a 4" tube
Lets start with adding some 3" wide flat stock to the 13" wide stuff I had so I could make 4" sides from the end result
I did a simple fusion weld with no filler for this

118336

After that I drilled holes for the ventury assembly and for the 1/4" round bar that supports the ash grate and pre-cut the corners with the plasma, leaving tabs to bend and hold alignment of the edges.

118337

The folded and assembled box

118338

Test run after final welding and assembly. Hard to see the smoke.

118340


Mounted on an old junk masterbuilt smoker that I ripped the electronics out of, direct wired the heater, and control the temp with a rheostat.
The original plan was to supply air via an aquarium air pump but mine wasn't up to the task so I re-configured for Shop air.

118341

Better shot of the smoke.

118342

With the heater off, this will cold smoke at temps below 100*

Ultimately, I'd like to build a smoker as well, but I have this now.
I already have ideas on how to simplify the build... 4" square tube for starters :)

I get to replace a axle shaft. Yay!! Who knew high rpm and locked front end in the snow with lots of turning would snap a stock d30 shaft Haha. It was a good 10 year run though with some serious trail time. I have a very noob question though. If I take the outer shaft out can I still drive the jeep to chase parts? Be gentle with your response lol

If you have a hub, yes kinda except the bearings won't have anything keeping dirt out. If it's a unit hub with a nut, no, the nut keeps the bearings together. I have in the past pulled the inner and put an expansion plug in the end of the tube, while keeping the outer in place to hold it all together.

TJ hubs are not captured. You need the stub shaft through the unit bearing to keep it from coming apart. JK Unit bearings are captured.

Thanks. I guess I'll just wait til the fiance comes home with the family hauler.

Well. Busted a ratchet trying to get the hub nut off using the jack handle as a breaker bar. Another first for me Haha. Guess I'll take the easy way out and just take the hub and outer together as a unit. Couldn't hurt to have a new hub installed.
