thanks, but that is a 98 1500, with dana 44, mine is a 96 with a dana 60, will those seasl still fit?
I contacted Spicer and they sent me the builds for every diff front and rear that made from 84 to 2002, but its a long acrobat read, and I'm looking in teh 96 section and all I can find is rears, its almost liek somebody swapped a rear diff for a front diff, but I know better this was a farm truck arond here it stays strock till it breaks, then it goes out behind the barn for ever

 

You might check out Post #5 in this thread.

@HeikIlm tends to provide solid tech and I trust his info

 

44 and 60 have the same seals, that is good to know because after searching through the spicer diff build sheets they sent me on Acrobat i did fiind the 96 D44

 

I have two pdf files that cover model years 1978-1998 and 1991-2001 I did not look in the 78-98 because you said you have a 96. (what you have is probably the same one i have # X510-9)
This is what i found according to the X510-9.
(Dana 44) 44895 Seal – Pinion Oil
The Dana 60 front and rear pinion is 42449(have several BOM's listed as the same #).
Axle seals take 47507 You need the BOM # for the other versions available which is what i was looking at in my previous post, My bad on that one! I bet that Spicer had National Oil Seal(owned by Timken) make the seals for them. I did find a spec sheet if anyone's interested. It gives you the specs for the seal and part #'s.

 

A timkin seal spec sheet, thank you I have teh Dana/
/ Spicer built sheets and now I can cross teh numbers when i'm done looking at the front end thats not supposed to be in my truck LOL
