    How To: Change front driveshaft / change a driveshaft head

    Those boots tend to deteriorate easily, so I stopped attaching a boot band to the shaft side and just fastened them loosely with a nylon band. This will slightly reduce the precession load on the boots. Grease moves outwards due to centrifugal force, so there has been no grease leakage for a...

    “Unstable Engine Performance and High LTFT1 Reading Issue”

    In most cases, a DTC will be issued and a check light will come on. If the damage does not meet DTC standards, nothing will come out. If I remember correctly, Since the correction value is -, the PCM determines that the air-fuel ratio is rich and makes a correction to reduce the fuel injection...

    “Unstable Engine Performance and High LTFT1 Reading Issue”

    Fuel trim is calculated from the O2 sensor value. It would be a good idea to replace the O2 sensor upstream of the bank that is over 30.

    03 Liberty 3.7 Transmission Line Pressure Sensor Location - at a loss

    Is this it? For 42, the pressure switch is attached to the valve body. There is an exposed upward facing connector on the right side of the transmission, but it cannot be replaced from the outside.

    Project to divert KK coil to KJ

    I also replaced the saddle on my child's bicycle yesterday, but that was more expensive.

    Project to divert KK coil to KJ

    I replaced the serpentine belt because I smelled rubber from the engine compartment. The belt had many cracks. It was a different part number than the service manual. For the 2003 model, the service manual lists only one belt option. Maybe someone replaced it? I don't know the correct length...

    2005 Jeep liberty sport - power steering issues

    You may want to try bleeding the air out. Without starting the engine, lift both front wheels and turn the steering wheel from lock to lock about 10 times, then add the remaining oil.

    strange "rotational" noise like a bad u-joint

    Check the transfer oil and differential oil. Shake all the shafts held by bearings and check for looseness.

    Project to divert KK coil to KJ

    surely. I also end up buying low-quality products without checking. Manufacturers with IR on their HP are generally fine.

    Lift problems

    That spacer is for a 3.5 inch lift. It has a height of 53mm, but the clevis set position is different from the stock, so it functions as a spacer of about 43mm, resulting in a lift of 86mm. The car body will be lifted approximately twice as much as the spacer.

    Project to divert KK coil to KJ

    I replaced the radiator because coolant was dripping at the bottom of the radiator inlet tank. The last time I replaced it was 39 months ago. This time I will refrain from mentioning the manufacturer's name. This is a Taiwanese manufacturer affiliated with DENSO. It is famous in the aftermarket...

    Lift problems

    It looks like an RC 3.5 inch spacer. It is full of inconveniences when it is fully extended. I replaced it with one that doesn't have a long strut length. At 1G, the ball joint boot separates from the spring. You can just put the tires on it and lower it to the ground.

    2002 KJ Fuel Rail

    Is it here? It would be safer to replace it to prevent a fire.

    2009 KK Jeep scalloped driver front tire

    That's right, the steering wheel is on the right side. The TIPM and battery are on the left, so there's plenty of space on the right side. There's no steering shaft on the left side, so if I remove the battery tray I can turn the nut with an extension. I guess I'm lucky.

    2009 KK Jeep scalloped driver front tire

    My KJ is RHD. I can access the nut from under the car on the driver's side without removing the steering shaft. Use a 50mm offset socket and a fine pitch ratchet handle. I can only turn it about 10 degrees at a time because various things get in the way. What about LHD KK?

    2009 KK Jeep scalloped driver front tire

    Good plan. As far as alignment is concerned, the steering rack bushings are also generally ruined. If it's installed the same way as KJ. The type where the ends of the sleeves are crushed and expanded. It seems that the oil that drips when replacing the oil element causes it to deteriorate, so...

    2009 KK Jeep scalloped driver front tire

    We rarely have the opportunity to test out several new shocks at the same time, so each new shock feels great. KYB is a Japanese company that definitely has the top share in the new car installation and aftermarket markets in Japan. Originally, the recommended replacement cycle for shocks is...

    Quart of oil every 700 miles

    In Japan, cylinder boring costs about $500 for a 6-cylinder engine if you remove the cylinder block and take it with you. It looks like it will cost about $600 for 6 oversized pistons and piston rings, but it will vary depending on the manufacturer. Liner replacement and honing will cost about...

    What did you do to your jeep today?

    My aftermarket radiator, which was only 39 months old, started leaking. I feel like I can use it by re-bending the inlet tank tab, so I'll try to repair it after replacing it with a new aftermarket radiator. The stock radiator had a pinhole in the inlet tank, so I threw it away. If I were to...

    You can also check with a multimeter. This is the upward facing connector among several connectors.
