Wow thanks. I am changing the oil as the car is 35 years old and it's probably never been changed, Thought it might be good for it
you might want to a least ...check the level...someone may have had a ...seal leak...at one time and didn't top off the oil... ...:Handshake...
FORD may not call for it, but it's not going to hurt a thing to change it. The oil itself may not wear out, but over time, the additives will wear out, and the oil will catch any metal that wears off, not to mention the possibility of contamination by water. On semi trucks, we change the rearend oil about every 250,000 miles, but look at the pressure it has been put through. I wouldn't think twice about changing it if it has over 100,000 miles on it. Oil is a lot cheaper than steel parts, but thats just my
you can pull the pinion support out by removeing the drive shaft then takeing out the 5 bolts right behind the yoke. Use a dead blow mallet or a pice of wood and a hammer aginst the yoke to get it to come forward. now oil will come out. you wont get it all out but you will get most. you can stick your hand in and scoop more oil out. this way you dont have to pull your axles. dont double nut the stucs out of the housing. they are not screw in they go in like a wheel stud with slines.
Or you can suck it out with a soda straw like the guy in the other thread needed to do with his overfilled automatic tranny.
I've always removed the fill plug then use a small hand plump to suck the old stuff out. Then fill up half way or so then pump everything out again. Then refill with correct oil or what it calls for until it spills out the fill hole and your done. If by chance you have a tralier hitch and a boat make sure that you have a vent tube above the water line when you back your boat and trailer into the water. or water will enter the rear end
