Suzuki Samurai -Gear oil, Stuck Fill Plug & Speedo Cable lube

Suzuki Samurai -Gear oil, Stuck Fill Plug & Speedo Cable lube. On this I go over filling the differentials, transmission and transfer case with fluid. I use two pairs of ramps to get the Jeep off the ground and make it level because Jeep needs to be level to check the fluid level. The fill plugs in the transfer case and the transmission were stuck since they were not removed in a long time. You want to use a 6 point 15/16 inch socket versus a 12 point socket (or a 24 mm socket) since a 12 point socket could round off the filler plug (which happened to me). I tried vice-grips to remove the filler plug but what worked was to use a Dremel tool and make the plug smaller and flatten the sides. I was able to fit a smaller 23mm 6 point impact socket on the filler plug and use the impact wrench and that got it off. If that did not work the final solution would be to weld a not on the filler plug. As a last resort, you can also fill the transmission and transfer case from the top, if it is bone dry of gear oil. Grease the end of the clutch cable where it pivots because if it is not greased well at that pivot point it will cause the clutch cable to flex and they will lead a clutch cable failure (breakage). For the speedometer cable, I used a hose over the housing and filled it with Marvel Mystery oil and turn the speedometer cable by hand with a screwdriver, until the oil worked itself into the speedometer cable housing and the cable turned smoothly.
