Oil leaking from where drive-shaft attaches to diff (pinion?) in '91 sierra. Is the seal easy to replace for a semi-novice? How much should I expect to pay?
P.S. Only found http://webseven.org/outerlimits4x4/view ... 7e06dd162f but did not describe how to repair.

Use cheap tools... Its better to break the tool than the part!
download a service manual and that way you'll get it right. Pinion seals a pretty easy I think.

Bingo - B4T is right.
In the FSM, Suzuki outline which jobs can be "short cutted" and which can't. As an example, the transfer case seals can be replaced with the transfer case assembled, but the diffs techncially can't.
The word from a very good diff guy our club members use is that it is kinda possible to swap the seal without a rebuild, but only if you could get exactly the same tension on the pinion flange nut.
The problem is deformation of the crush sleeve causing preload to back off, ruining the diff setup.
This is even true of diffs converted to a solid spacer, but it's not as hard to get the tension right as the crush sleeve doesn't have any effect.
The last three sierra diffs I have had apart have all had very bad wear patterns from poor setup. I have seen countless sierra diffs with very loose pinions.
Take it to a diff shop. the should charge $150-$250. Your diff will last longer as a result.
