Re: Diff/Gearbox oil change
Done exactly this job last weekend so have the info
Front axle SAE 140W API GL-5 (2 1/4 pints req'd). I couldn't get a straight 140W grade but put in SAE 85W/140 grade.
Transmission SAE 75W/85 API GL-4 (8 5/8 pints req'd).
Transfer box DEXRON ATF III automatic transmission fluid API GL-4 (2 quarts).
Rear axle Hypoid LSD oil API GL-5 (2 1/4 pints).
DO NOT USE GL-4 in GL-5 and visa-versa where recommended as this will damage these units
I found the front axle, gearbox and transfer box oils in good condition after 70K miles but the rear LSD oil was VERY black and burnt. This LSD oil should be changed every 36K miles BTW
Also do not use any of these so called 'oil modifiers' to change gear oils into LSD oil as they're a load of ***** IMO, get the right oil for the job
