or if you mean the big round one with i think 10 bolt holes like this? Axle Housing Gasket Part Number: RDS55084

Are you talking about Pinion Oil Seal. You need to take the yoke off to replace it, and never reuse the old nut, you need to get a new nut and it has to be torque down checked with a inch pound torque wrench, not a foot pound torque wrench to get proper preload. Hope this link helps a little- http://www2.dana.com/pdf/AXSM-8663.PDF

Actually you can re-use the nut IF you go about it correctly: the nut has been staked to the threads to keep it from backing off, so you need to run a tap through the nut to clean the dent out of the threads, then also run a die over the pinion shaft threads to clean them up, afterwards the torque is not effected by the deformed threads.
I have had good luck torquing the nut to 100 ft-lbs with the p-brake on, wheels chocked, this seems to get it tight enough without getting it too tight and collapsing the crush sleeve too far. I like to use a little thread locker and be sure to stake the nut threads to the shaft.
Timken # 474133 for the seal.
