Thanks! It’s been an adventure for sure. You’re local, you should join us for one of the norcal-jeeps runs.

Its always made me a bit nervous changing out front seals/harmonic balancers.

How did the pin get pushed into the crank? It threads in doesn't it?

The kit instructions said to use the non threaded centering pin to do the removal, and use the threaded version for the install.

Guess that’ll teach me to read instructions.

Got a call from FlyinRyan today, talked through what I'm running now, and what I'm planning.

Oh, and I got to tell him I've got an M1 4bbl on the way.

He'll be sending me tunes for the 5.9 with the 4bbl.

Can't wait.

In the name of freshening things up for the 5.9, assistant and I did a filter and o-ring kit on the fuel injectors.

Injector removal is pretty straight forward. Relieve pressure on the fuel rail, unbolt fuel rail, remove retention clip that retains the injector in the fuel rail, remove injector.

23 years on these injectors and they're definitely showing it.

Here's a close up of the fuel rail end of the injector. In the center is the filter, and you can see the degradation in the o-ring.
injector-filters-2.jpg

The intake side of the injector was a little bit better.

Some of the ebay sellers include a filter puller tool, but I didn't get one. A drywall screw works just fine, just thread it in and pull the filter out.

Old and busted vs new hotness

For pressing the new filters in, I found a c-clamp to be just right. You don't need to put a lot of pressure on them to press them in, but you do want to make sure they're fully seated. O-rings are pretty self explanatory. Reinstall everything and we're good to go. I wasn't expecting huge gains, and the 5.9 runs a bit odd on a 5.2 PCM, but idle smoothed out, and it feels like throttle response improved. I'm pretty happy.

Looks like a great kit. Can you repost the link? eBay doesn't like it.

Thanks

Be careful using Vaseline. Vaseline is a petroleum base product. It can affect certain types of rubber (O-Rings) and make them swell. you need to use a Silicone grease on O-Rings.

Hmm, link updated, let me know if it's still broken.

I installed most of the injectors without needing anything to lube up the o-rings. For the few that gave me trouble I just ran a finger along the inside of the oil fill cap and transferred that to the o-ring, lightest coating possible.

tl;dr: **** axle side front uppers, currie ftw

A while back I installed poly bushings in the front axle for the upper control arms. I had the front end apart, I didnt want to have to mess with them again, I wasnt going to spend a bunch of money on a d30, etc.

Cant say I was happy with the results . . .
johnny-joints-01.jpg

So after swearing I wasnt going to do anything more to this d30, I needed to do something about this d30. The bushings had gotten so bad that I could get a nice wobble out of them at around 35mph over train tracks. Every other joint in my front end is either a better poly bushing, or a johnny joint.

Its time for more johnny joints.

Currie sells a kit for our front axles, a machined johnny joint for the drivers side, and a flame cut bracket and johnny joint for the passenger side. Ive been recommending this kit for a while, and had been looking forward to installing it on another jeep.

Removing the old bushings was easy, they fell out. I did have to beat out the sleeve on the drivers side. The CA had enough movement that it mushroomed the sleeve.
johnny-joints-02.jpg

Here we have old and busted vs new hotness.
johnny-joints-03.jpg

Currie includes a tool to press the driver side in, its just a chunk of round stock with a hole to clear the ball center so youre pushing on the body and not the internals. Balljoint press works great to get that seated.
johnny-joints-04.jpg

I contemplated a tack weld between the housing and the joint, but Ill give it a chance to make me regret not doing that.

The stock bolts are a metric size, but currie ships 7/16 as stock size hardware. They mention that you may need to enlarge the holes in your CAs to 7/16, and I was a little surprised that I did have to do that to the core4x4 arms.
johnny-joints-05.jpg

On the passenger side the bushing and the sleeve fell out once the arm was removed. You dont even need to remove them, were cutting the bracket up anyway. The instructions talk about measuring 2.5 from the axle tube. I just marked on the bends in the bracket.
johnny-joints-06.jpg

Thought about the sawzall, grabbed the grinder instead for the cut. Once the stock bracket is cut up you can put in the new bracket section.
johnny-joints-07.jpg

I did my best to line it up where the stock bushing was located, but the currie bracket is a lot less direct fit than Id have liked. I got to the point where it was located close enough and burned it in. The real advantage here is that you dont need to weld to the axle tube at all (there isnt even a good place to if you wanted), just weld the stock bracket to the new one. No risk of warping the axle tube.
johnny-joints-08.jpg

Double checked the alignment (still garbage), greased and checked torque (still greasy, still torquey), and took it for a test drive (wheeeeeee).

Ok, yeah, I should have done this the first time around. Im even considering it for the XJ, and its 2wd.

Currie kit here: https://www.currieenterprises.com/CE-9102K
I didnt purchase it from currie, and it was a lot cheaper. They also have versions of the kit for the 2wd beam, and you can have stockish sized 7/16 hardware or upgrade to 1/2.

I have always used dipstick oil... or spit. No leaks yet but I have never had to remove one I installed, might be trouble coming...

Those currie mounts are great. I put them on my hpd30 when I upgraded and am very pleased.
