suspension question

i just got a T-MAXX from a friend, it has been setting in his garage for about 2 years, so i took it off his hands..... its got a full INTEGY suspension set-up on it, shock towers, etc. but the front right a-arms dont have as much down travel as the left side does, its off by about 1/16 - 1/8 in. Now i know this doesn't seem like much, but it seems to make it turn badly in one direction.... what can i do to fix this problem? any ideas of why its like this, both sides seem identical.....
