    Sudden vibration/noise from blower motor (VIDEO)

    So all of a sudden, the blower motor in my 2005 KJ is vibrating and making a really objectionable noise when the blower is on 4 (which it needs to be during the summer). It can also start making the noise when it's on 3 and the Jeep goes over a speed bump or similar. I've had the motor out, and...

    Has anyone replaced their evaporator?

    AC is losing refrigerant and it's been traced to a hole in the evap. Deep joy. Has anybody pulled their dash to replace the evap? I've done it in my ZJ, and there's a quick'n'dirty way that means that in about an hour, you can get the dash pivoted away from the firewall far enough to access...

    Anyone changed the evaporator in their KJ?

    I've got a leaking evaporator, which obviously isn't so great with summer on the way. Has anyone tried doing an evap replacement in their KJ? There are various writeups for the ZJ that show you to get to the HVAC box with drastically less work than the full FSM procedure - about 2 hours...

    KJ cut out while starting, now won't start at all

    Went to start my 2005 KJ, and it seemed to start OK - it cranked for about a quarter of a second. Then the engine just stopped. Now when I turn the key, I get the dash lights, but nothing else - no clicking solenoid, nothing. It won't start in neutral either. Battery shows 12.6V and the posts...

    Removing rear driveshaft

    If it doesn't rain this weekend I'm planning to change the U-joints in my rear driveshaft. I've never had it out before. I just remove the bolts at the diff end and then slide it towards the transfer case, is that correct? Am I likely to need a persuading device (i.e. a BFH) to get it to start...

    Anyone replaced their brake booster?

    I've confirmed my hissing brake problem as the booster. I've looked up the FSM replacement procedure and it looks straightforward enough, but actually looking at the booster, it's pretty cramped in its corner. Has anyone changed one? Any traps for the unwary?

    Brake pedal hissing when pressed

    I'm getting a hissing sound when I press the brake pedal. Just in the last week, we've noticed that we need to put more pressure on the pedal about halfway through a stop. I guess this probably points to the brake booster? I've tried the FSM test for the booster - engine off, pump the pedal...

    Torqued UCA bolts with Jeep in the air

    I've been running my KJ with a new passenger-side UCA and LCA for about 2 weeks now, and I torqued the bolts when the Jeep was still in the air (I only torqued the front bolt, the rear one I just snugged up as much as I could). Since I now know that you shouldn't torque the bolts until the...

    Any pointers on changing the motor mounts?

    I'm hearing that replacing the 3.7L motor mounts is a PITA, even though the FSM makes it seem very straightforward. Does anyone have any experience of changing the mounts with the engine in the engine bay? The driver's side mount is supposed to be the worst to do.

    Front brake caliper pin-and-boot kit discontinued by Mopar?

    The Mopar front caliper pin-and-boot kit for the '05 KJ is listed in the 2005 parts catalog as 05019987AA, but it seems to have been discontinued. Can anyone confirm this? And if I have to go aftermarket, can anyone recommend a kit that definitely fits? Having done some Googling, it seems...

    Why are the front LCAs so expensive compared to the uppers?

    Even aftermarket there's a huge price difference between upper and lower. What's so special about the LCAs?

    Getting the "random misfire" code, but driving is smooth and no CEL

    I was getting the CEL along with the codes for random misfire, cylinder 2 misfire and insufficient ionisation in cylinder 5. I decided to replace all the plugs and coils - all but coil #1 were the 2005 factory originals. The KJ now has noticeably more zip when pulling away from stationary. I...

    Safe to jack front end from the skid plate?

    I've had my ZJ up on jackstands many times, but never my KJ. That's all about to change :) Just wanted to know recommendations for where to jack the front end. I've done some Googling and many people say they do it on the front control arms, but the FSM specifically says *not* to jack on a...

    Replacing motor mounts - do you need an engine crane?

    I'm sure I read somewhere that replacing the motor mounts in the 3.7L requires supporting the engine from above, you can't use a jack from below. Is this correct? If so, it's not a DIY job for me :(

    Any way to remove slack in throttle cable?

    There's a fair amount of slack in my throttle cable where it meets the throttle body. Is there any way to tighten it up? The throttle response has been off for a while, so I was wondering if that might be the cause.

    Where is the sensor that tells the Jeep that you haven't buckled your seatbelt?

    Occasionally, the warning lights for the airbag and seatbelt will come on while driving. I've read that this can be caused by a fault in the sensor that detects whether your seatbelt is buckled or not. Can anyone tell me where this sensor is? Logically it has to be in the belt receiver, doesn't...

    Overheating after rad replacement

    So I finished replacing the rad in my KJ this morning, and I followed the FSM technique for refilling the coolant, which says to fill the bottle to the fill line, replace the cap and run the engine with the heater set to max. Of course, the coolant in the bottle disappeared within a short time...

    Does this sound like worn motor mounts?

    My 2005 KJ feels like it's vibrating just a tad too much on idle. You can feel it mainly through the seat - not a major vibration at all, in fact my wife doesn't even notice it at all, but I do. Since the engine sounds perfectly smooth and the rev needle isn't fluctuating at all, could this be...

    Second OEM radiator leaking - is there a better aftermarket alternative?

    My second OEM radiator has a slow leak. I understand that it's a known issue with the plastic side tanks. Is there anything on the aftermarket that's better built?

    EVIC going bad - time to replace, or can it be repaired?

    The EVIC in my 2005 Limited has started doing weird things. You have to press the SET button multiple times before it registers, the elapsed time counter will randomly freeze for a while (but it keeps counting while the display is stuck because it will then jump to the correct time), the...
