A buddy of mine has recently taken possession of an unfinished project rig û ItÆs a Mazda Pick-Up, sporting 42ö Swampers, with a Dana 60 front, and what I believe to be a GM Corporate 14-bolt rear.

With the cover off of the D-60, I could see that the ring gear is stamped ô3 11 75 DANA 13320Aö, with another more lightly stamped impression that says ô653ö.

It didnÆt even occur to me to turn the pinion shaft and count (vs. one revolution of the ring gear) until after I got home (DUH!)à and a web-search last night proved utterly fruitlessà so I was sort of hopping that someone here might know what weÆre looking at.


IÆm asking, because if the ratio is appropriate (and the price is right), there is a remote possibility that these axles might one-day find their way under my Rodeo! <img src="/forums/images/graemlins/kewl.gif" alt="" />


Anyhow, any information would be greatly appreciated û TIA!

The best way I know to verify the ratio is to count the teeth on the pinion and ring gear and calculate the ratio.

example: ring gear 43 teeth, pinion 9 teeth 43/9=4.7777778 <img src="/forums/images/graemlins/smile.gif" alt="" />

Those numbers you got more than likely won't help you out. Looks like it might be a date of manufacturing. Whats the BOM? sometimes you can find out from that.

but like Andre said, with the cover off, why not just go ahead and count, then you'll know without a doubt!

EDIT: I was just thinking... smiley, if you do ever find yourself with a D60 under your rodeo, you're gonna want more gear than any available factory ratio. IMHO gear ratio is a poor excuse not to buy a D60 if the deal is good enough.

Further, Smiley - if this thing was running tires that large, it probably got regeared at some point. Jack one side of the rear axle, spin the tire and count the revolutions of the driveshaft. Quick, easy, etc.

Oh, and then buy the axles.

According to what the previous owner told my friend Paul, the gears have already been swapped to match the tire sizeà but whether thatÆs true or not, he still has no idea what the ratio actually is.

(Like I said, it didnÆt occur to me to count the revolutions until I got home. <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> )



*If* Paul sells it as-is, he intends to unload it as-a-whole, and not part-it-out û and he has a pretty firm figure in his head of what he needs to recoup from the sale of this thingà And admittedly, itÆs more than a wee-bit out of my price range for the total package.


The thought occurred to me that maybe I could sell the wheels and tires to help me whittle-down the outlay û but that would leave me in-need of a set of wheels and tires (then again, on the other hand, honestly, I donÆt think IÆm quite ready to jump straight from 32s to 42s! <img src="/forums/images/graemlins/scared.gif" alt="" /> - Not to mention the fact that I donÆt have the cabbage to fund a SAS project right now either).

I know that an opportunity like this only comes along but so oftenà but *of course* this one has to happen when IÆm in no real position to do anything about it. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />



Maybe it would help me if I had some idea of the itemized real-world value of these bits and piecesà

Assuming the following:

* A GM Corporate 14-Bolt rear & a D-60 front (geared with æ?.??:1Æ)

The D-60 looks like THESE:







* Four 8-lug aluminum wheels, with 42ö Swampers (with maybe 30-40% tread)
* Springs (front + rear + a spare set of rears)
* Various other bits and pieces (of unknown compatibility)
* A Mazda Pick-Up body and frame (most likely for scrap)


Ballpark; roughly what are we looking at here?
(even your best æSWAGÆ would be greatly appreciated!)

Thanks again!

If these axles are geared for the tires it would have to have the 5.13 gears in it. That is the lowest gears that you can get right now for those axles to match up. the 14 bolt axle is the bad link here so to speak. It"s lowest gear is 5.13 right now, however there has been talk that they ar making the 5.38 gears for it.

So lets say that these axle are gear with the 5.13 and they look realy well. I have seen them axles sell for as high as 4000.00. Are they locked? If you can pick them up for anything less then 2500.00 I think it would be a deal.


good luck,
Daniel

unlocked with stock gears....the D60/14 combo could go for $700-1200...........guess it all depends.

price goes up for matching gears 4.56+ and lockers and new brakes, king pin kits, bearings, hubs, u-joints, etc

the clean up and painting helps the sell.........


rears are dime dozen and not worth a whole lot typically...... $100 +/- down to free around here.


really would need more info on the other stuff.


what's the asking price for all this stuff?

i am also noticing from the pics there are no wheel bearing hubs? Does he have them or was it a Dually converted to single wheel

the Cast hubs alone go for average of $175 each if you need them.




the steering is stock so it looks like this stuff never actually made it into the truck right?

Yeah ummmmm, My price was for the 2 axles with matching 5.13 gears,lockers and in good shape.(nothing needs to be done to them)

Is the 14 bolt converted to disc brakes?

Later,
Daniel

No Sir... not yet you don't! <img src="/forums/images/graemlins/pfft.gif" alt="" />



Seriously though, thanks for the info!


I was guessing that they might be 5.13:1 (assuming that the front & rear are matched in ratio)... I'll see if I can confirm this in the next 24-hours or so.


The thing that I noticed about the D-60 that caught my attention was how the knuckle assembly is configured, with the knuckle positioned at the rear (and I swear that it was a flat-top, and not dropped/recessed like the ones in the photos above).



Condition-wise, they look pretty good overall - painted black (no locker in the D-60 - I don't know yet about the rear).


I'll update again on this one just as soon as I have something more to tell - and IÆll be sure to take LOTS of photos <img src="/forums/images/graemlins/kewl.gif" alt="" />
