For a 1987 Suzuki Samurai axle, it's recommended to use 80W-90 gear oil, which is suitable for most differentials. If the vehicle is operated in extreme conditions, a synthetic 75W-90 gear oil may also be used for improved performance and protection. Always check the owner's manual for specific recommendations and ensure the oil meets API GL-5 specifications.
'86 Samurai 5 speed transmission 1st gear final reduction ratio from the factory manual is: 3.652
Your transfer case may be in neutrual.
80w90 gear oil
GL5 75W90 or 80W90 gear oil.
There are three ways to find a gear ratio. 1 A dealer can normally tell from the vin number. 2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement info. 3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.
To add gear oil to a 1987 Suzuki Samurai's standard transmission, locate the fill plug on the transmission case, which is usually on the side. Use a socket wrench to remove the plug, then pour the appropriate gear oil (typically GL-4) into the fill hole until it reaches the bottom of the plug opening. Reinstall the plug securely after filling. Always consult your owner's manual for specific oil specifications and capacities.
roughly 2200 lb IIRC. I had an 86, that when fully loaded (er, overloaded) for a week's worth of camping in the Mojave Preserve, weighed in at 2900 lb...with all my gear, half a tank of gas, and me.
It is set correclty when the crush sleave inside is set, during a gear setup. then it is checked with a Inch pound meter and will show while rotating roughly 5 inch # rotational drag.
did you ever find out what caused this i am having the same problem
GL-5 for gear oil and for engine oil use 10W-30
Well you have to have the same gear in the front and in the rear of any set of axles so the tires spin at the same rate other wise you would wear your tires out from then skidding all the time, and or brake the transfer case gears...
80W90 in both use lucas or some type of synthetic like redline.
