  1. So I have a 96 Geo Tracker 5speed manual 4x4. I bought it from my uncle who said he had just bought a brand new clutch. However the vehicle when started will only shift into reverse. It won't shift into any other gear. If I start it with the gear in first the car doesn't lurch forward or seem to do anything abnormal, except once I shift to neutral I am unable to shift to any other gears except reverse again. When the vehicle is off I have no problem shifting to all gears. I don't have the slightest clue what to check. Any feedback could be very helpful.
  2. There's a lot of chatter about the use of dielectric grease. Permatex suggests that Dielectric Tune-Up Grease is a good barrier to oxidation at plugs, connectors and terminals. There are some online comments at forums that say not to place dielectric grease on connector pins. I've gone to the Permatex site, and the information is vague: "Protects electrical connections and wiring from salt, dirt and corrosion. Extends the life of bulb sockets. Prevents voltage leakage around any electrical connection. Also prevents spark plugs from fusing to boots. Required for modern high energy i
  3. I have recently purchased a 1993 Jeep YJ with a 4.0. The jeep recently started running and idling rough. The Check Engine Light (CEL) was not lit nor did it illuminate when the key was turned ON. After further investigation I found the CEL bulb was removed and found shards of glass in the socket. I removed the socket and added a new bulb. Upon further investigation I found the PCM is storing the following codes: 12 ==> Battery disconnected (accurate) I just did a head light upgrade and added relays. 27 ==> I have found a few listed on-line... Code 27 -Injector control circuit-b
  4. I just recently purchased a 1984 CJ7 Laredo. The Jeep is bone stock, including the 258ci engine, T-5 transmission, Dana 300 transfer case, Dana 30 front axle, AMC 20 rear axle, and hardtop. The previous owner took meticulous care of the rig. After many hours of research and visiting many parts websites, I was hoping for some advice on what upgrades I should install and how I can prioritize these projects. This Jeep will be used around town, on coastal foothill fire roads, and trails around Bear Valley, CA. So far I'd like to do the following items: Twin Stick conversion on TC 2.5 inch sus
  5. Originally a Q&A Vlog question at the magazine, a Jeep owner has trouble with the gauges and engine tune on his early YJ Wrangler. I suggest several troubleshooting and diagnostics tools for checking circuits, grounds and voltage drops. The use of a volt-ohmmeter, lamp load test and other techniques apply. Wiring integrity and proper splices are also discussed: Trust you'll find this helpful... Moses
  6. My son has a 1994 Cherokee Country, 4.0 that starts fine and runs fine, but when you shut it off, it will not restart until it has cooled off. I replaced the ignition coil but the problem did not change. My son has purchased a crankshaft position sensor, but before we install it, I wanted some opinions from other XJ owners who may have experienced the same problem. Once we have installed the crankshaft position sensor, it cannot be returned if it doesn't fix the problem. I am not even sure that not starting when hot is a symptom of a bad crankshaft position sensor. Someone that my son knows su
  7. Good afternoon, I'm looking for information about all that we should know before servicing an axle. I'm not an experienced mechanic, so I like to investigate before mess it up. Which one will be the best fluid to fill up the differential? I've read about API GL-5 and 75W-90 specs for this. I've also read about a limited slip differentials and an additive to be required for that one. So, how can we identify the axle that we have, starting with this, I've read that the D35 has a plastic plug. But mine has a threaded one. What things can we look for, to identify the D35 and D30 axles? How can
  8. Moses, a friend of mine is having a hard time with his YJ when he tries to start the engine. He said that some times take more than 10 attempts cranking the engine but it wont run. When we had luck and get the engine running, it suddenly dies when driving, becoming a critical safety issue as it loses power steering and brake boost. A mechanic took the ignition components to a lab for testing, he said that everything is OK. (Coil, Distributor, Wires and Ignition module). Please share some of your wisdom that can help him to find where the problem is. Thanks in advance.
  9. Forum Member Alberto from Colombia did a rear axle lube change on his recently purchased 1989 Jeep Wrangler 4x4. He discovered that the Dana 35 rear axle differential case is missing the lock pin retainer for the pinions/spider gear shaft. This is a crucial safety issue and deserves its own topic. Here is a copy of my response to Alberto, we can discuss this further: "Alberto...The "missing" lock pin retainer on the pinions or "spider gears" shaft is very important, as this lock pin holds the pinions/spider gears shaft in place. Warning: If the pinions/spider gear shaft works its w
  10. One of the best lessons learned from years of instructing and our forum discussions is the value of visual learning! Now, the innovative Vimeo On Demand streaming HD video program enables the streaming of 4WD Mechanix 'Tech and Travel' How-to Series HD videos covering a wide range of subjects. Under the 4x4 hood and chassis, on the motorcycle repair stand or from the work bench, I'll deliver step-by-step, close-up HD video details for shop technicians and serious DIY enthusiasts. As you would expect, the growing list of instructional videos will demonstrate best professional practices an
  11. When you find that your engine repair includes cylinder honing, apply this process properly. The optimal honing finish will have the right cross-hatch pattern with correct angles. If you're unsure of the right "look" or angles, look closely at the photo below, the magazine's cylinder barrel after machine honing at L.A. Sleeve Company: Hand honing will involve the correct diameter stone hone or flex hone ("glaze buster"). Your cross-hatch pattern will depend upon the right pressure and speed of the hone as you run it up and down in the cylinder. At our tools forum, you will find m
  12. We all know the value of anti-freeze/coolant. Anti-freeze is essential for preventing casting cracks when you park the vehicle in freezing weather. By contrast, the coolant properties raise the boiling point of the solution, making our modern engines tolerate higher operating temperatures, which can provide more complete combustion of fuel and cleaner tailpipe emissions. Higher pressure radiator caps also help raise the boiling point. Every liquid cooled engine parked at below freezing temperatures requires anti-freeze. Specifications call for anti-freeze/coolant that is compatible with en
