first of all wanna say , short time reader, first time poster. found the website while searching the web and WOW, what a sight, i have learned a lot from you guys. but anyhow, i was doing a little minor wheeling when two side gears broke in the posi unit. has anyone had this happen before? is there any tips out there for replacing/rebuilding? i believe the unit was faulty from the factory. when it broke it wasn't under that much strain, and i have done alot worse to smaller units. the exteneded warranty is going to cover the expense, but i'm not sure of the longevity of the used/rebuilt unit vs. the new unit from the factory. we are almost positive they are not gonna spend the 4600 for a brand new unit.

i guess dodge makes it and CUMMINS brakes it.

If your extended warreny is fron chrysler, then they will repair if possible or replace the whole carrier if not

It must have been a faulty unit. I've beat the tar out of mine and it's held up and I've got the smaller rear axle (60 or 70 I don't remember).

Hmm, usually only the real high power hard core guys can break an 80...something must not be "right."

Don't want to beat a dead horse here, but here goes Is it a Powr-Lok or a Trak-Lok? As we all know, Tlok's are absolute junk and the Plok is the very best you can get.....I don't care what anybody says about Tlok's - they have proven to me to have a much lower torque handling capacity than a Plok.....I would venture to say that every time I here of a Posi failure in a Dana axle, it is a Tlok.....That said, even a Tlok will put up with a "little" abuse before it folds, so it sounds like there may have been an existing problem....

Kipo,

If you have the opportunity, make sure a Plok replacement goes in the axle and not a Tlok....

I'm not part of the diff group you guy are in but I'm running a good ol' peg leg rear end... I beat that rear end pulling logs, cars, trucks, rocks, trailers, etc... Still got good gear lube and check it once a month for color and chips (if any)...

Sound like someone need to point him in a new direction on where to find good aftermarket part for it... Since CTD Nut shown that factory isn't going to do it...

Unfortunately, from what I can gather from what the dealers are doing is that even if the truck was factory equipped with the Plok, the service replacement part # for the complete carrier now crosses over to a Tlok. So, it appears you could be screwed either way if you chose to have the dealer service the carrier - even if you had a Plok, it will be replaced with a Tlok!

thanks for the reply guys. i'm not sure what the difference is between the two, or which unit is in mine. but we have found a used unit with approx. 60k on it, and is equipped with disc, and a posi. not positive on this info yet but i will be going to pick it up myself to drill the junkyard salesman. and i agree with you big blue, i've put some smaller units through much worse and have no problems. the only upgrades i got on my big blue is an afe stage 1, banks 4" w/power elbow, banks high ram and wastegate, and superchips programmer. the programmer wasn't in at the time of the failure. the problem i have now is the warranty people, (which is not chrysler) is thinking about crawfishin' on the warranty. i should hear from them today with their answer. either way i will be putting the used unit in for now and rebuilding the core for a spare. the hard part is finding aftermarket parts for an 80. their hard to come by.

What parts are hard to find for a D80?

kipo

well i was looking for a detroit locker and aftermarket axles, i found the detroit locker, but the ring and pinion and detroit locker are still eluding me. i also found out today that my extended warranty reps came out and looked over the truck with a fine tooth comb. they even had my mechanic locate the computer on my truck and take a picture of it to e mail to them. they wanted to make sure i wasn't running any kind of chip on the vehicle. they gave my mechanic hell for the high ram intake and the afe stage I but determined that would not be enough to void the warranty. now they are trying to avoid paying by telling me that because my rear tires (255/85s vs. factory 238/85's) are 1.25" taller than factory that they are giving the odometer a false reading. but they still fell under the 5% false reading. they are still sending another adjuster out tomorrow to go over the computer with a fine tooth comb. my question to you guys is , what kind of history does the computer store if i used to programmer a time or two during the past few months. ?? it has tripped no codes, no check engine light or nothing i can think of ever. but will the computer store the performance settings in a memory , even if it has been returned to stock , like it is now??

Sorry to hear the bad news. I blew my dana 80 last summer, one of the spider gears lost a tooth and went between the ring and pinion and destroyed all but the carrier. I had to wait for replacement parts for a while and that sucked - they had trouble finding a ring gear ( at a resonible price). The rebuild with after market locker cost $4000.00 cdn - ouch. If you can find a good used one, you may save some cash.

Good luck, Bret

kipo, if they wanted to dig deep enough into the computer they could find out you had a programmer on there but I doubt they will go that deep.

phox_mulder

Sounds like they are digging pretty deep already.

Fine tooth comb and all.

I would be willing to bet only DC's DRB scanner would have the capability to retrieve that kind of historical data.....that 5% odometer reading is a bogus claim if you had the revs per mile adjusted accordingly in the PCM for the tire size you are running.....

kipo

will disconnecting the batteries clear any type of history from the programmer? that's just a rumor i heard but don't know myself. what exacty is a dc dbr scanner? my mechanic, who's been a lifelong friend might have one? but the adjuster will be there today and we will see.
