Update your signature to include a description of your truck: year, engine, trans, 2 or 4 wd, any modifications done

Doesn’t the CC use the “football “ bottle, while the one pictured is the “grapefruit “ bottle?

I did get it a few years ago. You can try searching for similar models. I bought it at Best Buy.

I had to remove the dash bezel. Then pull out the radio. I adapted the wiring harness. Also routed the microphone under the dash and up the A pillar

vacuum bottle. It holds the vacuum to control all the parts that need vacuum.

I installed a JVC KD X50BT. Bluetooth ready. No more cassettes or CDs, just link to my phone

How fast are driving in 4H? What road surface are on? A 231 is not meant to be driven as AWD.

Congratulations. My wife and I just celebrated 30 years.

The 87 probably needs bleeding. Sounds like there’s air in the line. The 89 may have a bad (going bad) slave cylinder. Are the the trans original? Internal slave cylinders

I guess I lucked out. I got an AX15 from a 90 XJ (int. slave). I purchased off ebay an ext. slave bellhousing. I installed this in my CJ. I bought another one off craigslist for $300. Seller said it came from a 98 XJ. I installed this one in my MJ. Both work well. The MJ gets lots more miles since it my DD. The CJ has been a WIP rebuild for the last two years, so it isn't getting many miles. I found the one from the 90 shifts better than the one from the 98.

4. The clutch should match the trans. When you order the clutch kit, be sure you get one for your 98 AX15. The pressure plates changed from the internal slave to the external slaves. I've had good Luk with Luk. 6. Yes. I have an AX15 from a 98 XJ, also. My cable just screws on. I did my swap in one weekend. I started taking things off on Friday PM and had it all back together on Sunday. A trans jack is MOST useful. I rented one for my CJ swap. I bought a Horror Fright jack for about ~$100. I've used it a couple times. One issue I ran into was the loaner pilot bearing/bushing puller. The tips would not fit inside the old bushing. I ended up pushing out one of the dowels that holds the gripping tip. I then put tips inside the bushing and put the dowel back in puller. The loaner slide hammer made quick work of getting the old one out. (There are lots of videos on U-tube about using grease/bread/wet paper towels. I tried one on my CJ and all I ended up with was wet paper towels jammed inside the bearing. The bearing never budged. After cleaning out the paper towels, that was when I learned about the puller not fitting inside the bushing.) Good luck. Post script: To take the knob off the shifter, use a heat gun on the cap top. This will soften the outer portion. You can then pop the center cap out without scarring the outer portion. The nut to remove the knob is under the cap. To install, heat the outer portion to soften it and slide the cap in to place.

Is your Cat going bad? A blocked exhaust system will cause similar symptoms with the engine. A bad cat will emit a funky smell (so I've heard, never experienced). BTW - fill in your signature with details on your MJ: Yr, engine, trans, 2 or 4 wd, any modifications done to it.

Correct. The ECU will trigger the ground that will complete the control charge. The relay will not power the FP until that ground is provided. My point being is that if the Org/Blk was cut then the ECU is not "directly" providing that ground.

Do you have the electric service manual? It's the 88 year, but the wiring for the FP is the same for 87. See page 16, The center top of the sheet is the FP relay. The yellow comes from the ignition switch and charges the control side. The Org/Blk feeds a ground to the ECU. The red comes straight from the battery and is hot all the time. When the control is charged, the relay sends power to the FP thru the ballast resistor (if yours has one). It also sends a signal back to the ECU. If the Org/Blk was cut from the relay, a PO must have bi-passed the factory wiring.

The Org/Blk wire from the relay feeds a ground signal to the ECU. If that wire is cut, the fuel pump relay will not send power to the FP. A PO may have made a work around that you have undone with your new FP.

To make the purists (I am one) happy would be to buy a junk XJ and swap the front fenders. Keep the originals intact and cut up the replacement. (Or keep the replacements for future use.)

I watch the first episode. Looked interesting, but he spent a lot of time setting up for the testing. Tried watching the second episode. After falling asleep while the guy continued to set up for testing, I lost interest. Someone let me know how it turns out.

Must be something in the MJ that is causing this. You're #2 with a child. Congrats!

Shirt looks like a CJ5. He could probably reach the pedal now.

Congratulations! (Pink hat - girl, correct?) My little girl just went off to college this year. The year's will fly bye rapidly.

1. The default fuel trims are 128. ST adjusts faster. LT adjusts based on the ST trend. Fuel trims <128 = rich condition; >128 = lean condition 2. The O2 heater relay operates on 12v. The o2 sensor operates on 0v - 5v. It should keep jumping from low to high. 3. I routed the wire along the firewall, over the booster, then through a hole in the top of the firewall next to the fuse box. I then routed under the dash into the back of the ash tray, where i have the REM sitting.

Mine came stock with 225/75/15. When I upgraded to 235s, my speedo was off 3+/- mph. If yours came from Jeep with 215s (stock size on some models), then your MPH may be off 5+/-. http://www.novak-adapt.com/catalog/transfer-case-parts/np-speedometer-gears edit: if you changed your tire size but didn’t change the speedo gear accordingly, your MPH will be off

Here's a thought - has the OP changed out his speedo gear? Since 235/75/15 was not a stock tire with the MJ, if he still has an original gear installed, he may be reading a lower MPH than he is actually running (ask me how I know this). So, if his speedo shows 70, he could be +5 MPH higher. Faster speed = higher RPM My 2¢.
