Ok Baja Gurus I need your collective wisdom.

I have put 3 steering servos in my new Baja 5Tsc and its starts out great turning awesome and slowly starts to lose steering till there is non in forward . Strange thing is if I apply the brake wheels turn but not much maybe a few degrees. I take out the servo looks like it works great i cannot manually hold it when i use remote to turn it. Reinstall it like I am supposed to and same problem. Can you guys help me ?
