2006 2500 Axle Identification
From : john
Q: hi - just bought a used 2006 ram 2500 4x4. i am not sure what axle is in the truck and was wondering if anyone out there can identify it from the vin below. i know theres no lsd but im wondering what lsd/locker options i have but im not sure which axle it is and what ratio. this is the gas engine not the ctd. many thanks in advance! 1d7ks28d96j219456 .

hi - just bought a used 2006 ram 2500 4x4. i am not sure what axle is in the truck and was wondering if anyone out there can identify it youve got the aam 10.5 rear axle. cant tell the ratio from the vin - it may be stamped on a tag on the rear differential cover. to guestimate your axle ratio lock out overdrive or if its a manual run it in 5th gear at 60mph and note your rpms. calculate the diameter of your tires as such if you have a 245/75r17 take the width in this case 245mm and divide it by 25.4 converts to inches. multiply by the aspect ratio 75 in this case so multiply by .75. double the number then add the rim diameter 17. so 245/25.4*.75*2+17 is 31.46. multiply by pi 3.1416 to calculate the circumference - in this case 98.86. divide 63360 number of inches in a mile by your tire circumference - getting 640.9. thats your axle rpm at 60mph 1 mile per minute. divide your engine rpms at 60mph when the transmission is in 11 ratio by your axle rpms and youll have your axle gear ratio. if youre turning 2400rpm at 60mph thats a 3.74 ratio. the closest gear ratio offered is a 3.73 so that would be your gearset. .

a sinpler way it to jack up one rear tire and rotate it one turn and an even more sinpler way might be to raise the hood and look up for a sticker. my 99 has one there that lists all the hardware specifics. i dont think theyd do away with something that convenient no matter what the manufacturers cost saving might be. -- ken .

on tue 08 may 2007 022653 +0000 max dodge rebooted the etch-a-sketch and scribbled you know i wouldnt be suprised if toyota hasnt been talking to navistar hoping to get them to place either the 6.4 or a newer engine in the tundra if they break off with ford. that would make sense for a number of reasons. only argument against that would be the fact that isuzu is the worlds leader in automotive diesels. well dont they use duramax diesel if toyota were to work with them it would be like some other automakers utilizing toyotas hybrid system.... ...oh wait... .
