rear diff gear oil change...

[lucky03602]

ok i have searched and asked around and still no answer...

first off a comment about the 1990 240 spec chart under faq section...so far all the gear oils i have come across sell them in quarts, not pints its kinda hard to figure out much to get/put in unless you do math or look elsewhere

anyways im gonna be buying some redline 75w90 gear oil for my car, i was thinking to get it for the transmission and my non lsd diff.

when you guys talk about m/t90 you mean 75w90 and not straight 90w right?

and i know that the 75w90 is safe in the transmission, but what about the rear differetial, it calls for 80w90 gl5 and redline doesnt make a 80w90 oil that i have come across.....

no one has an answer?

from what i've been told there is two drain plugs one on the bottom and one on the sidei guess ur supposed to fill it up until it starts draining out of the side drain hole, thats what i did and havent had any probs with it

meh... 2 pints=1 quart

75W90 GL5 is ok for the open diff... N E ways, you'll haveta fill until the oil oozes out of the fill hole (w/ a leveled,lifted car)

[lucky03602]

yea i know how to drain and fill it i was just curious as to if the 75w90 was in the diff, thanks.

as for sanioll i did search, i tried rear diff gear oil, rear diff, rear differential, differential oil, transmission oil, transmission oil, gear oil, 75w90, and a couple others.

i didnt try differential on its own you got me there, but as far as callling me a newb and a liar is going a bit far and actually a childish act. so say what you want but how you say it makes you look bad.......

[sanioll]

sorry for offending you, but i did word my sentence carefully.I said "youre not telling the truth". lying and not telling the truth are totally different things.

but yeah, if you go with mobil1, then 75w-90 is okay for summer and really good for winter.
