    1998 TJ Steering Gear Input Shaft Seal

    That's a really good video JPNinPA. It looks like the cylinder seals must be leaking, since there doesn't appear to be a seal at the end of the stub shaft. Maybe best to just buy a rebuilt gear at this point.

    1998 TJ Steering Gear Input Shaft Seal

    It's definitely coming from the input shaft, or stub shaft as it's referred to in the FSM. There's not really a procedure outlined in the FSM for replacing the seal in the Jeep, it just describes how to remove the gear and tear it down. Looks like there are a bunch of o-rings and teflon seals in...

    1998 TJ Steering Gear Input Shaft Seal

    My steering gear is leaking from the input shaft end.... There's nothing else wrong with the steering at this time, I'm about to sell the Jeep so I don't want to get further into this than needed. Have searched but not found a lot of info or videos on doing this seal, everything I've found is...

    New Engine - No Crank How to tell if it's the Computer?

    Thanks for the help, I went back and checked the connections again and that's what it was. Idiot that I bought it from busted the tabs that hold the connectors together rather than take them off right so I had to go back and zip tie them all together. Pffft.

    New Engine - No Crank How to tell if it's the Computer?

    Also, the CEL never comes on. I believe it would normally come on when the key is turned to the 'on' position and then go off after the engine starts.

    New Engine - No Crank How to tell if it's the Computer?

    So here's my latest- I jumped the BR/LB wire to ground (terminal 13 from the starter relay in the PDC), according to the wiring diagrams it splices with the PCM and goes to ground. I've been unable to trace it all the way down but if there's a break between it and the PCM then the PCM isn't...

    New Engine - No Crank How to tell if it's the Computer?

    I don't see the CEL come on at all- it won't crank, so it won't start. It's a manual trans. I happened to have a computer out of a 2000 Grand Cherokee, threw that in there to see what would happen. Same thing...no crank, fuel pump running with key on. Lights come on, everything else works...

    New Engine - No Crank How to tell if it's the Computer?

    So I spent months building a stroker for my '98 TJ. Got it in, hooked everything up- won't turn over. When I was pulling the motor I forgot to disconnect the battery (duh) and grounded something out that melted the fusible link. I replaced that and have tried the following: Checked every...

    Harmonic Balancer Woodruff Key - 4.2 Crank

    So this seems incredibly stupid but maybe I'm not the only one to find this out. I'm building a 4.6 stroker using an early 4.2 crank in my '98 4.0 block. The crank was machined several years back for another project and sat on a shelf until I started this build about a year ago. Somewhere along...

    Oil Pump - Difference between Melling M81 and M81a?

    I have a new Melling M81 left over from a 4.2 build that I never did and am now building a 4.6 stroker out of a 4.0 block and 4.2 crank. I am not sure if I can use the M81 in my 4.0 block or not- I see different information in different places with some saying they are interchangeable. But a...

    1998 TJ AX15 Transmission Pops out of second gear on decel....

    I took everything off so I'm looking at the shifter and top of transmission through the hole in the body- took it for a drive, the shifter isn't contacting the body at all at any time. When I'm driving along in second it just pops out all of a sudden. I'm starting to think it's the shift rail...

    1998 TJ AX15 Transmission Pops out of second gear on decel....

    Hi again JPNinPA! It seems you are quickly becoming my personal advisor. Glad to have your guidance. This was happening all the time before I pulled and rebuilt the transmission, hot or cold. it’s been cold here in Atlanta since I got the Jeep back on the road, but I don’t think that’s the...

    1998 TJ AX15 Transmission Pops out of second gear on decel....

    Hey guys, My TJ was popping out of second gear on decel, I decided to tear it down and overhaul it. I did all that, got it back in and drove it tonight, everything is great except it still pops out of second on decel. The gears were all in great shape, and of course all the synchros and...

    TJ AX15 Transmission Mystery Part

    Thanks JPNinPA! I have the trans/transfer case installed, have looked everywhere and still don't see a place where this part seems to go. Guess I'll find out if it's critical or not soon....kind of doubt it. I appreciate your help!

    TJ AX15 Transmission Mystery Part

    Yeah I don't see it in the diagram either. I put all parts in bins in order during disassembly, this must have been something that came off early in the process since it was in one of the first bins. Can't be part of the master cylinder since I haven't touched that. Guess it can't be that...

    TJ AX15 Transmission Mystery Part

    Hey Y'all, I pulled the AX15 transmission out of my 98 TJ about 6 months ago with the intention of rebuilding it (it was popping out of second gear when decelerating, driving me nuts). I pulled it all apart, got a master rebuild kit and ended up getting distracted by other projects. It sat on...

    98 TJ #1 Injector Problem

    It was the connector...got one from the junkyard and everything works like it should. Thanks!

    98 TJ #1 Injector Problem

    Yes, 4.0. I just bought it, the previous owner bought it not running from someone else and put the ECU in as part of the work he was doing to it. He replaced injector #1 and it looks a little different from the rest of the Siemens Deka injectors which is why I swapped #2 with #1 to see if the...

    98 TJ #1 Injector Problem

    I'm getting code P0201, Injector Circuit Malfunction-Cylinder 1. Noid light flashes but it seems dim to me (same on all cylinders). Swapped #1 and #2 injectors, cleared the code and drove it, P0201 again. What could be going on? The ECU was recently replaced. What should I test now?
