Ok, what did I do!!??

2002 Polaris sportsman 700.
I simply changed the front A arm bushings. Now, something in one of the front hubs binds badly when you move foreword or in reverse.
I only jacked the front up 1-2 inches only to take tension off of A arm to loosen. Changed bushings then put back down.
What did I do????? IT feels like the left front hub is binding.

Any help would be appreciated.
Thank you!!
