Re: Thatxjguy's 1999 Jeep Cherokee Build 'Hole in the Pocket'

I've been spending pretty much all month tracking down this noise, and I'm pretty convinced it's a flex plate knock:

Re: Thatxjguy's 1999 Jeep Cherokee Build 'Hole in the Pocket'

My new injectors came today:




These are the Ford version of the 4-port 784 injector upgrade for the 4.0L.




The four-port injectors are plugged in now, and luckily, the motor didn't blow up. So now I'm waiting to see the results. I should see better MPG over time. I do notice better throttle response, insanely smoother idle, and also, a faster acceleration.

Also, in regards to that possible Flex Plate knocking, I bought a new flex plate from O-Reilly's just in case. That way, once it's apart, if it happens to be cracked, I can just swap it out.

Let us know how the mpg works out with the new injectors. I have been thinking about that mod for awhile now.

Looks good, my 99 is the same color. I like your stock wheels, mine has the factory steelies.

Re: Thatxjguy's 1999 Jeep Cherokee Build 'Hole in the Pocket'

I'm not so sure what to make of the upgrade so far.

My gas mileage doesn't seem to have "improved" at all. And perhaps the throttle response was an illusion – since resetting the PCM, throttle response actually feels weaker. I do seem to get better mileage at certain higher RPM speeds though. So it might be a "just broke even" kind of deal that is better for some applications, and worse for others.

I just refilled my tank with a full topped off tank from Chevron for the first time since the install, and I'm waiting until EMPTY to see how many miles I was able to travel. Will post results when the tank is empty.

I am noticing that the Jeep likes to start harder. I'll hear a loud "click" noise after the starter turns the motor over, and sometimes, the engine will even slug and feel like it's going to stall out before starting. That never happened before with the factory injectors. I don't really like the sound of the noise. I know the starter is good.

I replaced a broken lug bolt today that I snapped while doing a tire rotation (duh).



The aftermath after trying to extract the broken bolt from the lug:



I ended up just buying a replacement lug nut for $2.50 at Advance Auto Parts and I got the replacement stud from a buddy of mine.

While down there, I also played with the front driveshaft and felt some play.



New U-joints ready to go into the double-cardan front driveshaft.

Re: Thatxjguy's 1999 Jeep Cherokee Build 'Hole in the Pocket'

Today, I picked up a brand new 1998 Jeep Grand Cherokee (ZJ) tie rod assembly for a V8 model.



The ZJ tie rod is a direct bolt-on mod for the XJ that replaces the pathetic rolled sheet metal tie rod. It's also a much beefier solid steel tie rod, which is great for over-sized tires:

Got the dinky little XJ tie rod out today:



ZJ one installed:



It has the new adjustment sleeve:



The steering is noticeably stiffer, and when I hit bumps, the wheel doesn't move. It was a GREAT upgrade for the oversized tires for the price.

Re: Thatxjguy's 1999 Jeep Cherokee Build 'Hole in the Pocket'

Previous owner of my Jeep tried to kill me today!

After installing my ZJ tie rod, I decided to go and get a professional alignment. Everything went well... until the manager test drove my Jeep.

When that happened, the steering gave out. The manager called a wrecker and and got my Jeep towed back to the alignment shop. Luckily, he was only going 5 MPH when the steering gave out. It could have been me driving the Jeep when it went out, and I could have been going highway speeds – I'd have been done for.



Anyway... it turns out that the previous owner rigged my steering intermediate shaft in such a half-assed way that it just came un-done. You can visibly see the wear and tear from the bolt not being seated high enough to fit into the notch:



The rust also goes so far up the splines that you can tell the sleeve that goes over it wasn't seated all the way over it. In fact, it wouldn't even reach:

Holy crap, that's scary! Good thing no one was hurt.

A good friend of mine just had a caliper fall off (completely!) on his 4 Runner which caused a complete loss of brakes. The shop that did the brakes didn't tighten the bolts after doing a pad slap. He had just gotten off the highway as well but thankfully was able to slam it into park.

Yeah, it was a real eye opener. It makes me anxious even driving it anymore.

Re: Thatxjguy's 1999 Jeep Cherokee Build 'Hole in the Pocket'

After having found out that the mechanic that took the Jeep for a test drive and broke the steering had broken the clock spring too, the shop was happy to buy a new one and install that for free. So now that's in.

Today, I fixed the fact that the rear view mirror fell off. Easy fix.

And I also installed a Putco H4 wiring harness for the headlights.

Putco harness came today:









I'm not using halogen headlights, I'm using LED, so I have no idea if I'll even see a brightness difference. Fortunately, everything does work correctly. I'll see tonight if it actually makes a brightness difference.

On the other hand, although it's a crap shoot, I only paid $2 for the harness. I used all my Discover card cash rewards haha.

Lots of people on CherokeeForum like the upgrade, and I figured I'd give it a shot.

Tested out tonight and the Putco harness didn't really do much for the brightness of the trucklite LEDs. On the other hand, it's still good that it takes some strain off of the light switch, so I guess I'll keep it for that benefit.
