  1. Re: took a bath with my Grand Cherokee need help

    Well lets hear the rest of the story, how did things eventually work out for you?
  2. Re: took a bath with my Grand Cherokee need help

    Been my experince that anything that moves and is packed with mud will soon fail. Most mud is mixed with sand. Pressure wash everything, check for mud traps, those places it gets into and doesn't...
  3. Re: 1990 4.0 cherokee how do i change from fuel injection to carb

    I'd go down to Home Depot and buy a $3 volt ohm meter, Test the CPS for ohms. my guess is it will read around 180 ohms or higher and you need a new CPS. If the ohms test out OK, scrub the...

    Re: Where is the fuel pump relay?

    My first guess was he had a connector making flaky contact someplace or a ground making flaky contact. Usually when the ballast resistor starts to go, it will starve the fuel pump of current (low...

    Re: Where is the fuel pump relay?

    The fuel pump relay routes current for the fuel pump through the ballast resistor, which actually lowers the voltage to the fuel pump. The current to the fuel pump is supposed to go through the...

    Re: Where is the fuel pump relay?

    The noise of the fuel pump priming the fuel rail when the key is turned to run is kind of subtle. I'd check for spark while cranking the engine over. If you have spark, look at the front of the...

    Re: Where is the fuel pump relay?

    There are 3 or 4 relays in a block (row) about where the PDC goes in later years. The fuel pump relay supplies power to the ballast resistor after the motor starts (good CPS signal) and also primes...

    I'm not getting exactly what your problem is? It will not shift automatically?

    Re: Where is the fuel pump relay?

    Supposed to be second from the front. But on my 88 it is in a different location, so it is likely there are some variables.

    What is your problem? It is likely I've seen it before. I've been...

    Re: grand cherokee laredo question

    The IAC is the idle air controller. With the throttle plate closed (foot off the gas pedal) it is the only way for the motor to get air at idle (foot off the gas pedal). They get sticky and/or the...

    Re: grand cherokee laredo question

    Which engine? If it is the 4.0 the IAC is worth a look. They usually screw up worse when cold. Two reason for intermittent problems with the IAC, on eis something in the charging system isn't...

    Re: Cherokee hub question

    I'm pretty sure they are M 12 bolts, but hardened, 10.9 equal to a SAE 8. I remember using a regular socket, half inch drive to get them out, nothing exotic. Getting the hub off is a whole other...

    Re: Steering box

    Here is where I get my steering boxes, Lares Corporation.
    Tire balance usually hits around 60 MPH/110 KPM. Bad U-joint is also a possibility, especially the front axle U-joints.

    Re: very bad backfiring with black smoke

    I read somewhere that the rear O2 sensor makes sure there is enough extra oxygen for the newer type catalysts to function properly. It has to have some sort of trim affect on the fuel to air ratio. ...

    The book says the dark green should be near battery voltage with the engine running and the ASD relay energized, voltage into the field windings. You can test this at the green wire disconnected...

  18. Re: Brand new owner GC with rear axle seal leak

    I'd check the wheel brake cylinder, you can usually tell by the smell if it is brake fluid or differential oil. Pretty common for the rear brake cylinders to leak in XJ's, likely the same on the GC....
  19. Re: Battery Light and Charging Problems, Please Someone

    The green wire is supposed to be power in to the field winding, the orange and green wire is to the regulator (in the PCM/computer). It is actually regulated on the ground side in most newer...
  20. Re: how to remove bearing race rear axle 04 grand

    Re: hub assembly

    How hard do they turn (new) after you torque them down? If you can't turn them using, say, three fingers on the wheel studs, they are likely too tight. When I put my Moog hubs in and torqued them to...

    The only time I'd think about a rebuild is catastrophic failure or very low compression.
    Remove the small air vent line from your valve cover and blow through it, it is likely plugged. Then blow...

    Re: to many problems part two

    I'd address the smoking issue first. Run your finger inside the exhaust end opening and see if it comes out oily. Smell the exhaust, does it smell like fuel or oil? Pull a few plugs and see what...
