    Early TJ Ash Tray Switch and Gauge Panel

    It has been a common thread here to discuss ways of replacing the early TJ ash tray with paneling for switches or gauges. I’m here to let y’all know about an ebay seller who is making custom printed resin panels that can be made to your order. The product is smooth and well formed. His original...

    Smaller Diameter Rear Shocks

    Howdy. Things are tight in my TJ's back end. GenRight extended range tank, larger cast iron diff cover (diff turned up to match angle with the double cardan rear shaft), Banks Monster exhaust. I've just found that the Banks pipe is too close to my right rear Rancho RS55240 shock. A smaller...

    TJ Speed Sensor Connector Pin Configurations

    I’ve run into this issue as part of my tranny swap. The official word is that early TJs had speed sensor connectors in a three round pin configuration, but this was soon changed to three flat pins. My Jeep, made in late January 2000, came with round pins. The sensor shipped with the rebuilt 231...

    P030n Misfires and RPM Valve Rotation

    Some time ago, I was part of a discussion here concerning engine misfires with codes P030n. I stated that my long time practice had been to clear incipient misfires and rough idling by revving the engine above 3200 RPM in order to rotate the valves. Almost always, a few seconds above 3200 have...

    3550 fall down, go boom

    Last week, I bought a gallon of Red Line MTL, just to have on hand. It has worked beautifully for years in my NVG3550 5 speed, factory installed in my 2000 TJ. Last Tuesday, I junked the BFG AT/KO3 tires in favor of new Falken Wildpeaks. Thursday, 2 days later, I heard a bang down low and had...

    Replacement Lug Nuts for Alcoa Wheels

    I have run Alcoa Mickey Thompson forged aluminum Challenger wheels on my TJ for nearly 20 years. Long out of production. The lug nuts were specials, hollow and outside threaded for the chromed plastic nut covers. Handsome when installed, very rare now. I have lost some covers and others are...

    Odometer Mileage Reduced

    Howdy, Jeepers. My 2000 4.0 TJ has been in shop jail a bunch of times in the last year. Recently, I fired my old shop and found a really good one. Also, recently, I got an oil change and noted that the mileage logged for the last change was about 1500 miles higher than that shown on my odometer...

    Jeep TJ Lift Gate Glass

    Howdy, Y'all. My 2000 TJ with hard top is in fine shape, but I'm laying in spare parts that I think have a limited life and may be hard to replace as time goes on. Already, in response to my mechanic's pleas for parts I've been able to supply a Mopar radiator and Bosch fuel pump. This time, I...

    OEM 4.0 Block Heater Location

    Howdy, Jeepsters. My 2000 TJ is 21 years old this month and the factory block heater cord has been coiled up in a seatback pocket for at least 18 of those. Now, here in the Texas Hill Country, we have single digit temps predicted for early next week and the TJ lives outdoors. I can't recall...
