bikedoc,

gearwrench = racheting combo wrench

the box end of the combo wrench rachets-- sometimes you flip them to rachet the opposite way, sometimes they have a little lever to switch rachet direction, like a socket. great for tight places where you don't want to remove the wrench from the bolt/nut as it's a pain to get it back on it for another rotation. although i usually don't severely torque on them. commonly, i think they're 12pt.

question for those who drop the diff, is there any more room for RTV application doing it this way than raising the engine?

when i did the timing chain and raised the engine, there wasn't much room... i guess if the truck was jacked up and then the diff dropped, there'd be more room?
