guys I am putting aluminum a arms on truggy. What is the best way to remove pins that hold hex nut adapter and dog bones on? Is there anything else I need to watch out for on replacing steering knuckles hub carriers and a arms? Wnat about changing fluid in shocks and differentials? Please help this is my first time doing mods on hellfire. I have been reading the hellfire thread and all the stuff you guys have been breaking and weak parts I am putting on right away because I know the boy will be trying to run me over with his revo!

DUH figured out the pins in the hex nut adapters! Guys any secrets or tips you have I could use I am a motorcycle and gocart mechanic, just learning revo and hellfire mechanics. I am gonna put a 15t clutch bell on and aluminum clutch shoes, with gold springs. Anything I need to know before I do this? I am also putting a hitec titanium geared servo in and putting different differentiasl fluid in any advice would be appreciated!
