Yes, that is your rear final drive or rear differential. At the looks of it you will be needing a whole new unit. Doubt if you can just get the housing. If you can, reassembling the old one to the new housing maybe very difficult. You can get it online. Try courtesy parts or partsfornissans and compare. Also call around your local garages. If you are doing it yourself, replacing the whole unit should be doable. Download the service manual first---posted here somewhere---and study it well before anything else.

How the hell did it happen? What year and mileage? Are you still driving it?

It was my aunt car and she said when she was driving the car on the high way she heard two popping noise
Well she haven't told me until the next day that she call a Nissan dealership I think it was gonissan about a flat tire she got on the high way and she told me that one of the mechanic there told her to put on the spare even he should have know that it was a AWD car and it was going to mess it up.
Since I'm a master mechanic myself and I work at a Nissan dealership too I told my aunt to call that guy back and talk to him
And the car has over 130,000 miles

No i have it at my job

I'd have it checked because something had to cause the housing to crack so something has to be bad inside I'd think.

sk-

I am a little confused.

Are you suggesting the spare may have contributed to the cracked differential housing?

This is my first time running across this problem so I ask around other mechanics said yea the donut spare put pressure on the differential so it crack

nipsirc · 12-07-2011, 11:49 PM

I think they towed it with the rear wheels on the ground moving rather than flat bedding the whole vehicle it as it is an AWD.

streetkingz · 12-08-2011, 10:33 AM

When it was towed to my house it was a flatbed but when towed to the shop I wasn't there

streetkingz · 12-08-2011, 10:35 AM

I'm just going to order a whole new unit thanks for everyones help

Someone please correct me if I am wrong, but isn't the spare the same diameter as the regular tires? And if that is the case the spare should not have contributed to the failure, correct?

When I see or read about about a failure in a system the M.E. in me always want to reverse engineer how it occurred. A cracked differential housing on a MO is a failure we rarely see here. A trashed transfer case, yes. A cracked pumpkin, no.

I have used the spare tire for almost 100 miles few years back and no harm done. I don't know what that guy is talking about. He is full of it. Yes, I have the AWD too.

Perhaps the spare was severely underinflated, or it wasn't the proper spare for the vehicle. Towing with the rear wheels on the ground should not blow up the transfer case, but the vehicle should have been flatbedded to begin with.

HVT · 12-08-2011, 04:01 PM

I can't see the spare causing any problem like this....even if it were a smaller size since the Mo uses an open rear differential.
