Which Dana/Spicer Differential Do I Have?
From : hboothenospam gte net
Q: okay heres some frustrating stuff... i have a 2002 2500 4x4 and at 69k my rear diff is leaking fluid from the pinion seal. i buy a replacement seal because the dodge dealership can tell me from my vin which rearend i have. supposedly a dana 80. yea! im so excited. not! my shop manual that i have on the truck doesnt list diffs by dana 60/70/80 only by rbi248 rbi267 rbi286. now this wouldnt be a problem except that the torque spec on the pinion nut is around 215-330 for the rbi248 and 267 but 440 yes foot-pounds for the 286. needless to say im interested in knowing for sure which one i have before i turn my 37k truck into the worlds largest and costliest paperweight. i took my diff tag number to my local dodge dealership and explained how *their* shop manual listed them by those three numbers/models yet they had only been able to give me dana numbers and the said thats all they could find out. obviously the shop mechanics have some way to tell what truck has what 248/267/286 rear-end so they can look up the torque spec/procedures on each rear-end. can someone show me the light on this my diff tag has on the first row 52069477ak and on the second row 3.54 space 606710-2 tia --hc .

440 ft. lbs. iirc in the shop manual. my impact removed the nut with no problems use a new nut politics the gentle art of getting votes from the poor and campaign funds from the rich. um say not to be a smartass...but *how* important is it to use a new nut im not saying i needed the truck today and just put it back together with the original nut and no lock-tite...but lets hypothesize that i did...is it that bad a thing to do first time its ever been apart i bought the truck new. is it seriously all kidding aside worth pulling it back apart and putting a new nut on it if its really worth doing ill do it gladly but i wanted to ask first. thank you for your reply and your time. --hc .
