haynes says hypoid 90s by duckhams, except i can't find that oil online.
its a sierra (7"?) open diff, from 1.8cvh. 3.92:1.
tried my favourite opieoils.co.uk but cant find the relevant specs listed, or not complete, wondering if the specs have been updated. haynes lists
sqm-2c 9002/3 -aa
any help appreciated.
i'm using redline lightweight (not superlightweight), seems to work well and smells gorgeous
Duckhams brand was shut down by BP because they decided to concentrate on the Castrol brand.
You must use a GL5 oil
Hypoid gear oil EP90 to GL5 is specified any quality brand will do Comma, Castrol, Carlube
Unlike normal gears the gears in Hypoid final drives are subject sliding friction need a viscous EP lubricant don't be tempted to run
light weigh lubricants the lightest you will get away with is EP80 GL5 or EP75/90 GL5

i've heard people use atf in manuals before, but i remember reading somewhere that bgh geartech the type 9 gurus didn't recommend it.
