XRAY - Model racing cars

Hi Guys,
I just replaced the front drive shafts (305326) of my T3 U.S. (2010). Now, inexplicably, everything vibrates and the front when the steering is more than the system makes the engine work harder.
I also have the 008 T2 and T3 the new 2011 and everything is ok.

What am I doing wrong?

Thanks in advance
Pier

Did you replace short ones for long ones and now they are binding on the diff or spool out drives, esp if you run a narrow front end. Easiest way to check is take your shocks off and lift one side up as you rotate the other wheel, if you feel bind, the blades are probably rubbing on the out drive plunge.

Thank you so much! I checked Omocinetics and now after released it, cleaned and fixed, now everything is ok! Thank you very very much!
