Alright, I sound really stupid. And I must be blind or something, but I have looked all over the rear differential (the housing in the center of the rear axle, correct...?), and don't see two bolts on either side anywhere? I'm really confused.

If anyone (Steve!?) could post pictures, I would really appreciate it. I am at a total loss. I don't know what to do. This is all I need to be to complete my 90k service (extended over 10k miles!). But this way I will be on track for my next 30k service @ 120K miles.
If not, then I am getting a digital camera next week, and I'll take some pictures then and post them. Everyone says that you can't miss the bolts, well I must be doing something wrong. I can't find them for the life of me.

Thanks everyone (and ANYONE!) !!!!

I suppose I could just take it in.....!
