I don`t know anything about the rear end actually.
I have a book here that is the 1988 edition of the Haynes Manual for a 740 car,
but
it actually is for the 740 models with the gasoline engine (I have no idea if that matters)
and
it does not specify the fluid in the rear axle section of the book: `info not available at the time of printing`.
Then I found a some summary at the front pages, saying this (quoted, in red):
REAR AXLE
Except limited slip differential
Gear Oil SAE 90 EP to API GL 5 or 6
Limited slip differential
Special Volvo oil (No 1 161 276-9), or gear oil as above with Volvo additive (No 1 161 129-0)
But again, this is for the 740 GASOLINE car in 1986 or maybe 1988 too.
Im not sure what to use for my car because I have no idea what kind of a setup I have.
Just for safety`s sake, can somebody here confirm about this?
Maybe you know what exact brand and viscosity to buy.
Thanks!
PS. How can I check and confirm about what exact rear end the car currently has? I`ll try to look for a plate but I think the bottom of the car has been coated with some rubbery substance for rust protection plus there is dirt obviously. I don`t recall seeing any plates or markings there, though I didn`t really care to inspect thoroughly.
Maybe there`s a plate with the year, type and gearing; somewhere.
