Got my slash back together and ran it hard. The rear bulk had just been reassembled, and there was much dirt in the diff housing. After many hours of cleaning I got I back together and sealed the bulkhead with shoogoo.
The other problem I had was the driveline binding. Had to take the t-bone off, the stock skids off, and clean that out. The driveline was chewed up but fully operational. All cleaned out now and ready to go. So I threw some duct tape over the hole between the front shock tower and the transmission.
What can I do for a more permanent solution? I fear that shoogoo or other sealer would bind driveline.
