What are you looking to accomplish Matt? driveline, engine maintenance, etc?

I'd be sure to flush/bleed the brakes if you haven't, driveline fluids is a good suggestion, your option for trans, but the diffs and transfer case is a good idea at 100k.

If getting thrust arms done have your indy replace that ball joint on the arm as well (they are like $60 for the pair and can be done with the thrust arm bushing), also have him check condition of outer CV boots.

The possibilities are endless with yours, let us know what you've done so far....
