1988 414-8 rearend fluid

[fourwheels0 191]

what should i use for fluid in the rearend of my 1988 414-8 speed.

some say 90-140wt

others say automatic tranny fluid.

mine looks foamy and cream colored right now.

i don't think it's ever been changed or at least not in a long time.

gear oil, like 85-140 or 90-140 or straight 90, sometimes ones are harder to find than others.....a long job, that stinks litterally, but worth it. wally world has the best price.

personally I like to run the synthetic 90W stuff little more expensive but it seems thinner and pours easier.

If the current fluid looks like chocolate milk then it has water in it check the condition of the rubber boot where the shifter comes out of the tranny, new ones are available at your dealer for about $5

ok thanks.

yes it looks like a light colored chocolate milk haha.

the shifter boot look good with no cracks and is flexible still.

how much fluid should it take?.
