Jerry, I'll take you up on that exhaust offer in the future if I hit Laguna again. I don't think a supertrapp would do it without seriously restricting the engine.
I'm glad I found the wheel wobble when I did. Eating the event costs sucks, but it's a relatively cheap learning experience. Beats finding out when the part breaks on track.
After finding the wobble, I checked again with the car on the ground. Loaded, I couldn't move the wheel. It was only when I had it jacked up. There's a lesson there for me.
I'm still not sure if it's the nut or the bearing, but I imagine it won't take too much (time or money wise) to figure out and correct.
Actually, the thing that kind of ticks me off most, is not realizing sooner I wasn't going to finish the event. I could have spent that time cruising the aquarium with my girlfriend. I think I'll need to plan another, more relaxing trip.
The bigger concern for me now is that stub-axle bolt that won't screw in. I suppose I could just use 5 out of 6 bolts, but I'm only 5/6 comfortable with that. Not sure what it's going to take to get that thing to screw back in. Will I need to pull the stub axle out of the diff and find a replacement? I guess that wouldn't be too tough to pick up from a junkyard. I presume they just come out, and go in, with a pull hammer.
