Default Replacing Front Pinion Seal

Looks like my SS has the dreaded front pinion seal leak. My question is:
Can I change the seal without dropping the diff? If so how hard is it to remove the yoke and seal.

I already know there is no space to work in and I must mark the orientation of the nut to the yoke before removal and try to measure torque setting while removing any advise would be great, Thanks

you are better off dropping the diff. Mine had what looked like a leak from the pinion seal. it was actually the case halves right above the pinion was leaking. I had to open the case and reseal it.

if it were me, i would pull the diff, inspect all bearings, reseal the case, and replace axle seals and pinion seal.

it dont take much of a leak to run them dry and ruin beaings.

Thanks for the heads up,

The leak doesn't leave any drips in the garage floor but the end of the diff (where the pinion seal is) was wet. I noticed it when changing ball joints last month

When I changed the fluid there was only a half of a quart in it. I will just closely monitor and check fluid level until I have the time to pull the Diff later this summer.

I re-sealed my case and did the axle and pinion seals at the same time as well. Is the best way to do it since the pinion seal isn't the only leak point. Been flawless for 10k+

Front diff only holds a quart. You can be dry before it drips on the ground.

My oil pan and diff were wet. I was 1/2 quart low.
