    What did you do to your jeep today?

    Pull the plug and get a boroscope down there before you waste your time trying to replace the spring. See if the piston is damaged. Seems like you'd have to replace the valve too. That means pulling the head.

    Rear brakes

    I wouldn't recommend pinching a line off. That may damage the line. You could disconnect the line from the caliper and plug it. Then do the rebuild and reattach. You'll have to bleed the caliper anyway.

    Replacing 20028 TPMS Sensors with 29227

    Does your autel scanner plug into the obd2 or just go wireless? I have the simple one that is limited in what it can do. Can you enter the mode with existing id's and clone the last one that worked to the new one? Mine can't program but can clone.

    Rear brakes

    Looks like you should think about swapping out that caliper soon. Doesn't look like it's leaking at all but probably not going to last too long. You probably could just change the piston and seal but easier to change the whole caliper.

    P0508/P0522/P0688

    I'm not a Chrysler expert but I think it powers the coils, injectors and maybe the fuel pump. Probably more but not sure.

    What did you do to your jeep today?

    No one uses mirrors around me. Just gun it and go. People haven't heard of impenetrability, or they're trying to collect more data. Maybe they think they're bosons.

    CEL - Cylinder Misfire

    My 02 did that lights out thing a couple times. I wound up replacing the battery. It was an old battery and these things are pretty sensitive to any voltage drop. Is it charging ok? I also had a blinking #6 misfire at one point but my coolant reservoir had dripped on it.

    Wheel bearing or axle....????

    I'd definitely eliminate the possibility of the sticking caliper first. That could cause a hum that might be sensitive to turning. My next guess would be wheel bearing. Those are classic symptoms. That hum will continue to get worse of course, which will help the diagnosis. I've driven quite a...

    Did you put the sensors from the 02 in the newly installed 04?

    My Blue KJ

    Ain't that the truth! Mine are also both long gone. I keep looking for another KJ too, but things are expensive around me. Can't even find a decent project. Really pondering getting a KK. Never had one but always liked the look. Someday...

    Replaced coils and plugs but still have a misfire????

    Like LibertyTC said gap should be around 0.04". That's what the sticker under the hood called for with the copper core plugs. I ran that gap too but some will say 0.035 to 0.044. Opinions vary and it may vary with different types of plugs.

    Replaced coils and plugs but still have a misfire????

    Did you get a cylinder specific engine code? Should throw a P0302 for cylinder #2. What do the other plugs look like? Did you change all the coils and plugs?

    What cylinder is the problem?

    04 liberty 3.7 blown head gasket, I'm looking for a little advice please, here is my story.

    The CEL is a check engine light. Should throw a misfire code if one of the valves isn't opening. If you kept it running it would probably be a flashing CEL (little engine icon near gages). That means a hard misfire which is bad for the catalytic converters.

    04 liberty 3.7 blown head gasket, I'm looking for a little advice please, here is my story.

    These are actually hydraulic lash adjusters. If they don't pump up the rocker will be loose and can fall off. I had a #2 exhaust rocker fall off twice. Second time I replaced the lash adjuster and it never happened again. If the rocker wasn't damaged then just replace the lash adjuster. Pretty...

    04 liberty 3.7 blown head gasket, I'm looking for a little advice please, here is my story.

    Did it throw a CEL? Pull rocker covers and see if anything is obvious. Overheating followed by dropped valve seats is not unusual with these engines.

    2002 jeep liberty 3.7 limited burning oil

    I'd check the pcv system, the valve cover gaskets and the crank seal in the front.

    75W-140 Synthetic In The Rear Differential All The Time

    Yep. MPG thing. I ran the 140 in both mine as long as I had them.

    Crank sensor removal

    If the diesels are anything like the gassers, the sensor swells and is very difficult to pry out. So, be gentle when prying. I changed it on my 02 with the gas 3.7L but I had the motor apart to replace the crank.
