Hi, i have a question about my 3.3 engine. My revo 3.3 run fine but i find out the front bearing have air leak its that a big problem if i keep running or i have to change it?
ok i will change the bearing then. do i need to change both bearing or just the outter bearing becuase dont know how to remove inner bearing and inner bearing still in good condition
you might not even have to replace the bearing. Is there any visible damage? After you remove it, check it for damage, and if none, you can try cleaning it well, then reinstalling it back into the vehicle, and testing to see if it fixed the problem.
