Maybe someone's can answer this for me. I have Yukon 4.56 in my D30 front diff. I noticed changing the fluid that the seal at the point where the driveshaft goes in seems to be leaking.
Gears installed 1K ago and I changed oil at 500 and now, again at 1 K.
( as recommended by installer.)
My question is this, is that seal I need a different size from the factory one when I had 3.73? Do the seals change size with the gear ratio?
I want to get the right part.
Thanks in advance for info !!

The pinion seal has to be changed when you remove the pinion bearings. The seal is the same no matter what gear ratio.
