Great news, the strangeness of this build does not carry through to the tranny (except for the liberal use of what appears to be shock oil as tranny lubricant). All is well in the land of Drusky. Now to search for a bearing kit for this girl. Anyone know who sells sets of sealed bearings for the old stealth trucks? I'll go search the forum and post any info back here but as always your input is appreciated!
Here's what I have found after forum search:
http://www.avidrc.com/product/?c=1
http://www.bocabearings.com/main1.aspx?p=quicksearchkit&cat=1
Right then, I've just finished gawking at the manuals and here's the low down:
Stealth Tranny (9 bearings)
2 x 6589 ~ 5/32" x 5/16" (these are in the diff)
4 x 6906 ~ 3/16" x 3/8" (two housed in each side of the casing, they also happen to be the same as those used on the 10t fron axles and sc10 rear hub)
2 x 6903 ~ 3/8" x 5/8" (the large bearings housed in each tranny casing half)
1 x 6906 ~ 3/16" x 5/16" (lives outside the tranny on the slipper clutch, note it's OD is same as the 6589s but ID is different)
Wheels (8 bearings)
Truck:
4 x 6906 3/16" x 3/8"
4 x 6359 1/4" x 3/8" (if you're running the old 1/4" rear axles but if you want to run 3/16" axles just buy 4 more 6906 front axle bearings).
Buggy:
4 x 6902 3/16" x 5/16" (front)
4 x 897 1/4" x 3/8" (back)

Conclusion: If you're after ceramic bearing performance go to boca, they sell sets made up for your car, be prepared to fork out your cash. Avid doesn't seem to do sets but their bearings are very reasonably priced. I can make up a stealth tranny set containing some rubber selaed bearings where it counts for $10. Boca has a bog standard metal sealed stealth kit for $9.
