rear diff question
Bought ole red 5 years ago for $700, she's a 77 f-150, 400, c-6, full time 4 wheel drive, mechanicly when i bought her she was perfect, body was all rusted out but fixed her. Been an every day driver since. Question is rear end has started to growl ( checked oil and replaced u joints) the pinion comes out of the front of the diff, I'm wondering what kind of rear end is in it (theres no diff cover). I love ole red so she is parked until the weather smartens up and I can work on her. Any help would gratefully be appreciated.

Just wondering, does it have a metal tag on the bolt circle of the axle? If so, I'd be curious to know if it has a 3.00 gearing or 3.50 gearing, and also if it has a limited slip. If it has the tag on the bolt circle, could you post the numbers.
I also have a full time 4wd and it has 3.50 gears, but was told some came with 3.00 gears, and I would really like to know more about that.

The reason I posted that didn't have anything to do with wanting to switch gear sets. I thought all 1/2 ton 73-79s had 3.50 gears, but everynow and then you might find a full time 4wd w/3.00 gears, It was just a curious and what to know(if there are such things out there).
I plan on going to 4.30 or 4.56, haven't decided yet.

How about on the front diff(metal tag on the bolt circle of the cover), it should have the same gears in it, but the front won't have a limited slip.
Thanks for looking though.
