Replaced the front wheel bearings and possibly may have over torqued the castle nut when reinstalling the rotor. Noticed a noise coming from the front left side when driving home from work the next day. A 50 mile round trip. Suspect the spindal may be damaged now because a new bearing will not slide on but the old bearing does. Can anyone tell me how to remove the spindal or if I should try something else before going this far?

 

try taking a peice of emery cloth and sanding the spindle a little bit to see if you can get the new bering on ive see this work before.

 

would engine temp. sensor increase mpg on 240??

 

Probably if the old one is bad. Same is true for the O2 sensor. Those things have to work for the computer to know how much fuel to inject. Emissions reading would tell the tale.
