quick update ... i took it in to the dealer. it was indeed a leaking pinion seal. the 7/70 apparently has a $100.00 deductible. since i had 37000 miles they split that with me ... so i paid $50.00. craig c. .

i just noticed today that i am leaking diff fluid where the driveshaft enters. any help is appreciated. your pinion seal is leaking. is it still under warranty if so let the dealer fix it. if not we can talk about what it takes to change it yourself if desired. .

it has 37000 miles on it. 7/70 powertrain i think that was still in place for 04 i do have the extended warranty but id prefer to fix it myself since the dealer mechanics cause more problems than they solve. so lay it on me. whats involved okay... but it aint pretty. the official way to do it is to remove the driveshaft obviously - but mark its relationship to the pinion flange so you can put it back the same way then remove the hub bearings and pull the axles. measure the rotating torque of the pinion nut with an inch-pound torque wrench must be a beam or dial type and record. hold the flange with some type of fixture and back off the pinion nut an air impact gun works best. pull the flange out with a puller or slide hammer. remove the seal and replace with a new one. apply a light coat of grease to the seal lip and re-install the flange tap it in lightly just enough so that you can catch the threads of the pinion with the nut. clean the pinion threads with brake cleaner and put a little red loctite on the threads. put the nut on and tighten it - then check your rotating torque again. continue tightening a little at a time and checking until you get 3-5 in.lbs. over your initial reading. be sure to spin the flange around back and forth to seat the bearings before reading the torque. once thats done re-install the axle shafts bearings etc. etc. and driveshaft. sounds like fun doesnt it .

im a little confused about why you think you can fix it better than the the dealer and then you how to do it. then after tom goes through a as usual generous lengthy detailed and accurate how-to you take it to the dealer anyway. you paid for the warranty in the purchase price of the vehicle. why would you even think of doing it yourself especially since you dont know how to do it. .

john did opine im a little confused get use to it it only gets worse with age. about why you think you can fix it better than the the dealer and then you how to do it. then after tom goes through a as usual generous lengthy detailed and accurate how-to you take it to the dealer anyway. well if you read what i wrote i was under the impression that it was already out of warranty. since it wasnt and the instructions were a bit involved i decided to take it in to the dealer. however the instructions will not go to waste for i have printed them out and framed them so that when my truck is no longer under warranty i can fix it myself. and yes ... i can do a better job as a usual rule than the dealer and i have many examples to prove it. now what *i* am confused about is why *you* feel the need to mouth off to me about something that clearly is of no concern or bother to you in the first place craig c. .
