Umknown rear axle

The rear axle, is not the original, can somebody identify this part?, wich axle I need to buy in order to use the 4x4 option in my jimmy?

PS:
in other way, what mean married or divorcied transmission...=?

That rear axle looks like a earlier Ford 9" or possibly a Mopar 8.75".

Your transmission should be a SM465 and your transfer case is indeed a NP205.

Married transfercases mean it attaches via adapter directly to the transmission. Divorced means there would be a short driveshaft between the output yoke on the transmission and the input yoke on the transfercase. A married setup is stronger.

Yup, sure is. I had too many things going and typed the wrong thing.

Of US rears, Mopar, Olds/Pontiac (till 64), and Ford (till 56) had round center sections and no removable cover. I think maybe Cadillac and Packard too. All except the Mopar are too scarce to consider seriously.

However, considering where the OP is located, I think he is more likely looking at a Nissan or Toyota rear.

Nope. If it was an HO52 the center would have a cover held on with bolts.

Doubt it is a Toyota rear with that much width and beef. Also, if it had come from a Land Cruiser it would have a passenger side offset to the pumpkin and a bolt on cover similar to the Eaton.

Nissan Patrol could be a real possibilty. Not likely to be a rover though.

Did you drag that out of three feet of dirt?

Davetopay · 07-04-2010, 11:11 PM

The more I look at it, the more it looks like an old Mopar 8.75 axle.

The snout on the center section, the welds and the fill plug look Mopar to me.

raycow · 07-05-2010, 05:27 PM

I agree, it does look like a Mopar, but I just wasn't expecting to see one in Peru. The Nissan or Toyota rears I was thinking about are from the 2WD trucks, not 4WD. They have round welded covers.

How about giving us a little bit of help, like what is the wheel bolt pattern? Or maybe just a pic of the axle end with the hubcap off?

What lug pattern is on those axles? I suspect that front and rear both came from a different truck. Probably a Dodge. Is it five lug?
