Stock Ford, 8", 2.79 ratio, out of a 1979 Granada. Bought this used to convert to a V-8, 5 lug in a 1966 mustang. When I first bought it, one axle turned and one was froze up.
With the rearend assembled out of the car, turning the yoke- the axles dont turn. I disassembled and on the bench, out of the case-I turn one axle and the opposite side does turn the opposite way(I believe this is correct). but turning the yoke the axles still dont turn. Would some one have an idea what might be wrong. Thanks


The carrier is out of the housing-the ring turns when the pinion is turned.

something jammed between the ring and pinion, or they are rusted together? Throw an impact wrench or breaker bar on the pinion nut and see if she'll turn

sounds like wheel bearings are frozen, Hell just about anything could be frozen. You need to tear that thing down to the max and a rebuild is in order.
You can find rebuild kits on ebay for reasonable prices. Youll need someone to set up the pumpkin though for gear mesh, preload etc.
Good luck

Only thing I can think of is that either the ring gear or pinion gear have a problem...or more likely, splines on the pinion or yoke are shot. Dad's gone through a couple yokes...they can get loose and when they do, the splines are pretty much history.

Either way, I'd sure take the axles out, pull the pig and take a look-see.

You say you can turn one axle and the other turns the opposite direction, like you said that is correct. That tells you the spider gears are probably OK. The yoke should be turning also if it's not then something is wrong.
Sounds like the ring gear isn't engaging the pinion gear, or the clutch pacs inside are sooo shot the ring and pinion movement isn't having any affect on the spider gears.
Have someone turn the yoke at the same time you're turning the axles to see if you can influence from each other.
Better yet open the thing up and see whats in there.

If it turns opposite ways when you spin it, wouldn't it be an open diff and wouldn't have clutch packs?

My bet is on some bearing somewhere - probably the carrier bearings - if it were the wheel bearings you wouldn't be able to spin it by hand.

Update -I have the carrier out of the housing-the ring and pinion both turn.
