if the splines were completly sheared the rear wheels would not turn. if it is just catching on and off, you will know soon as they will shear completly if you drive it. If it is only in the transfer case, then you might be good and be able to install a new one if the splines of the...

if it is not going to see snow often, leave it like that. I personnaly took mine out so at least i removed around 100lbs from the car with the driveshaft.

where or how did they get a new diff? It says the part can't be purchased at Mazda, non servicable part. If you ever have a part number, please share it.

sorry that the pictures don't show anymore, photobucket... test http://u.cubeupload.com/pumalex/Photo140117113258.jpg http://cubeupload.com/im/pumalex/Photo140117113258.jpg

let us know what they end up doing to fix up the splines.

same problem here, now running in fwd. My transfer case looked good when i took it out, it is stiff because the oil is all jammed but otherwise, it still turns. I beleive the splines actually rust and get weak and then they break since the PTO is not harder to turn. Haven't found a replacement...

unlikely, when this happens the awd light is always on. either busted transfer case or chewed up splines in the front diff like i have. There is a huge thread on this a little lower.

ok because a constant 4wd light on means a problem with the rear diff, if it's flashing, it's probably the transfer case or the differential teeth,

it should be the same i beleive. when you pull it out, make sure it is not the teeth in the transmission that are toast. Although i beleive only 2007 had the differential teeth go out like that. Since you replaced the fluid, it is surprising it still went out. Do you have a flashing 4wd light...

just found this, anyone ever tried that? As far as i can tell, there was no way of replacing the diff Inside the transmission with the sheared splines, can this be the answer? https://maktrans.net/tf81diff-tf81-z-53-mazda-cx7-cx9-hyundai-veracruz

well if you can spin the wheels and the 4wd flashed that is because the rear wheel are not turning, i would check the transfer case. Best time to test it is in the snow but a slippery pavement might do the job too.

seems like a relay is not doing it's job or it might be the starter. First time i read about this.

you can always ask your mechanic to try to do the same thing, with the picture he might be able to do it.

do you have any details on how they replaced the spline hub? It is part of the differential which is a non servicable part from mazda. You can't even buy the part by itself.

no clue, i was looking for the same info on the transmission and no luck, this is not an engine that gets swapped a lot so trial and error is unfortunatly the only way to go but since we never hear about this...

You mean if you put back the PTU? it could but i suppose something is going to give in real quick, I still sugget you don't put it back in, will cost less in reassembly time and the car will be 100lbs lighter without the PTU and the driveshat.

honestly my fear is that the splines of the passenger side driveshaft do the same thing in the transmission, we can see i think on your pic that the inner splines for the passenger side are starting to weakens, at least, they looked like they did on mine.

WRONG, i currently converted my awd to fwd without putting back the PTU because i have the exact same problem as yours, splines shot in the transmission. i am now running it in FWD as it is not worth putting money into it. I can tell you fwd sucks in the snow with such a heavy vehicule but i can...

i don't know, if the engine doesn't start, the ecu won't have the time to go through the system to see the lean condition, unless there is a fuel pressure sensor, i doubt the ecu has a way to tell.
