Sample display of the RPM calculator. This is an excel spreadsheet I put together a little while ago whilst looking at the effect changing tyres would have on the general driveability of the JK.
Over time the sheet expanded to include petrol, diesel, auto and manual with all variations of gearboxes. Simply enter the tyre size and select the diff ratio and transfer case ratio then type in the speed and the approx RPM will be shown. (more…)
Having problem with water leaks on your JK? So did Jeep…
So, they brought out a service manual to fix the leaks! This is applicable for the older models, up to around 2010. Later models most of these fixes were already implemented but it is still handy to pinpoint where the water may be coming from.
We went out for a leisurely drive today through the Conondale State Forest, only for a good friend to discover when attempting to select 4hi that the transfer case lever felt like it was not connected to anything! He was stuck in 2hi!
This is unfortunately not an uncommon problem on the JK, the transfer case push/pull cable is held on at each end by a simple plastic clip which breaks with no real notice. I know it happens with older models, his was is a 2010, but I can’t confirm if it affects later models. (more…)
Just thought I’d throw in an orange jeep to colour co-ordinate with the rest of the graphics on this site.
