I've got a leak that empties my front axle oil onto the inside of my wheel. 1983 GMC Jimmy, 4WD, and I've never opened one before. I've had a look through the Haynes, and I'm about to put in an order for an axle oil seal. Please see if I've got this right: I have a full-floating axle because there's a hub on the end, with torx bolts. Now, the oil seal would be in the hub, not the axle itself, and therefore I need to order an inner and outer hub seal. Something like: SKF 22311 CR SEAL - Wheel Front (4 W/D) - Spindle Hub: Front Wheel 4 W/D; Inner. http://www.partsamerica.com/ProductDetail.aspx?mfrcode=SKF&mfrpartnumber=22311&parttype=914&ptset=A And then also get the 'outer' seal as well. Does it look like I've got it right? Any pitfalls or tricks to share? For the bearings the Haynes says a special spanner is required, but for the seals?
