    What did you do to your jeep today?

    A year had passed since the bases of the tread blocks on my Nankang MT tires started cracking, so I replaced them with Duraturn HT tires. They look reasonably rugged from the front, but a bit puny from the side. I must be careful not to drive on muddy roads.

    2005 No Bus issue - need help

    The cluster is probably fine. There may be a broken BUS circuit. In the 2003 manual, there seem to be many YL/VT colored wires. It's a good idea to check around the connector you removed. Some people may have been able to fix it by removing and reinserting all the fuses to ensure that all the...

    What did you do to your jeep today?

    It was the perfect storm for night snowboarding, so I went snowboarding at a snow resort 200km from my house, but if I had been five minutes later getting on the toll highway on the way back, I would have run into a road closure. On the north side of the mountain range, the only asphalt visible...

    YACNS issue (Yet another crank/no start issue)

    No DTCs have been output, right? Since it's not very reproducible, it seems like it's difficult to find the cause. Have you checked the fuel trim values with a scanner? Especially the long-term ones. It seems that LTFT is used for hot starts. LTFT is calculated from the O2 sensor values while...

    Water Pump questions

    Oops. I seem to have misread the parts list. I think BMWs and older Range Rovers had left-hand threads.

    Water Pump questions

    The HD's electric fan and the standard electric fan are different, so it will be interesting to see what happens if the viscous fan is removed from the HD. By the way, My 2003 model has right-hand threads. I think other model years are probably the same as long as the engine rotation direction...

    What is this part called? Air intake Reservoir?

    By returning the crankcase breather to a high position like this box, it becomes easier for excess oil to return to the crankcase. If the breather is returned to a low position, the excess oil will drip away rather than return to the crankcase. In model years where this box was discontinued, oil...

    The new guy with a problem, Go Figure.

    I'm not an expert on diesels, but have you checked the EGR system? It seems like there's a valve that tends to stick.

    What did you do to your jeep today?

    Thank you. The tires are Dunlop Grandtrek SJ6. 31x10.5R15. The wheels are steel wheels called Daytona in Japan. Daytona wheels for summer tires are made in the USA, but those for winter tires are made in China. Blizzak is said to be the least slippery tire in Japan.

    Questions on Liberty head

    Although the components appear to be the same except for the valve and valve seat.

    What did you do to your jeep today?

    That's right. In Japan, it's common to replace winter tires every three seasons, even if they're not worn down. Most people probably only use them for around 15,000 km. Even if they're not worn down, they're useless once they've hardened. When I was using 14-year-old dead stock studless winter...

    What did you do to your jeep today?

    In Japan, studless winter tires account for 36% of total tire sales, but in the USA that figure is apparently only 2.6%. They may not be very familiar in the USA. In Japan, the use of studded tires was probably banned around 1990, and since then tire manufacturers have been changing their tire...

    What did you do to your jeep today?

    I changed to studless winter tires. When new, their hardness is said to be 45-55A. Because there are many sipes, the blocks have low rigidity and are extremely soft. Since it's all about softness, it can only be used for about 3-4 seasons.

    Leaky seal / not sure

    Here's the link to the service manual on this site: https://www.jeepkj.com/threads/kj-service-manual-and-parts-pdf.60466/ I've attached a photo of the pinion seal for reference. It's unclear whether the pinion seal is broken, though.

    Valve cover gaskets

    It's a good idea to wash the exhaust manifold with water once. It's possible that a lot of oil got on it when you replaced the gasket. I used a parts cleaner with a long nozzle to clean the underside of the manifold as well.

    2008 v6 KK Overheating Issue

    The water pump may be operating erratically. Is the coolant flowing properly? I check this as follows: Drain the coolant from the radiator until there is no coolant left in the reserve tank, then add the remaining coolant. Air will accumulate in the coolant passages, and when you start the...

    Valve cover gaskets

    I had a similar experience. The grommet that came with the replacement gasket I bought was for a plastic head cover. It was 1 to 1.5mm thin. I had thrown away the old grommet so I bought a new plastic head cover and gasket. The gasket on a steel head cover is hard and has a single lip on both...

    265 70 R16 Falken Wildpeaks AT/4W on KJ with 2.5-inch lift

    I'm using 31x10.5r15 tires, which have almost the same outer diameter and width as 265/70r16 tires. I've installed the wheels in the -16 offset position with spacers. To be precise, the wheel offset is +19mm and the spacers are 35mm. With this wheel position, the outside of the front tire tends...

    What did you do to your jeep today?

    I painted the wiper arms and nut covers. I used a matte finish, but semi-gloss might have been better. Next I plan to paint the weatherstrip belts on the outside of the windows.

    Deestone M/S Bias tires on an '05?

    Near-new studless winter tires are fairly easy to control even when slipping on ice. They also stop slipping quickly. It's also a good idea to put spikes on MT tires. MT tires have larger blocks, so it's easy to make adjustments such as digging grooves and screwing in spikes. My summer tires...
