SOOO ABOUT A WEEK AGO, I INSTALLED A NEW STEERING GEAR BOX INTO MY 86 TOYOTA PICKUP 4X4, AND IT IS A MANUAL STEERING BOX SO IVE BEEN LOOKING AROUND FOR GEAR OIL FOR IT. APPARENTLY IT TAKES SINGLE WEIGHT 60W WITH A CAPACITY OF 400CC (SHY UNDER 1/2 A QUART) WITH 14-17MM SPEC BELOW THE FILL HOLE, IN 4X4s AT LEAST. ANYHOW, I CANNOT FIND ANY SINGLE WEIGHT GEAR OIL OUT THERE, I KEEP RUNNING INTO THE TYPICAL 75W-90, OR 80W-90s. ANYONE KNOW A GOOD PLACE TO FIND THIS OIL? OR PERHAPS AN ALTERNATIVE THAT IS MUCH EASIER TO FIND? BEEN THINKING ABOUT THROWING 80W-90 IN IT, BUT THE FACT THAT IT DOESNT REALLY GET HOT, IT WOULD BE A 80 WEIGHT PROB THE WHOLE TIME, ANY INPUT WOULD HELP.

 

WHOOPS......CORRECTION, IDK WHERE I GOT THT NUMBER, MEANT 90W. TO BE SPECIFIC hypoid-type gear oil GL-4, SAE 90W.

 

Hypoid type gear oil gl4, sae 90w

 

75W-90 or 80W-90 (or just about any gear oil) will be just fine.
