94' rear Pinion seal Help Please

[Lunatick]

I am going to be replacing my rear pinion seal (i think).
My dif is leaking from the front , where the rear of the drive shaft connects to the rear end.
My question is where can I find the id tag to determine what size seal i need to buy? There are 3 options.
My truck is 94' 4wd v6 sr5-.
Where is the id tag please? I dont want to have to wirebrush all the gunk off the entire rearend... lol so please help. Thanks in advance...

Lunatick, while sometimes you can get away with just popping off the worn seal and replacing,

Some times No, the sure way to do it is to tear it all apart replace the crush sleeve, and re set pinion preload,



pop the seal out, measure it and get it that way, pound it back in, do not reset the pinion preload by replacing the crush sleeve, and some mechanic down the road like myself will have a nice gravy rear end build to do,

Thanks for the advise, I feel im best to let a trained / experianced mechanic do this job for me ... Cheers___
