Flatliner;

Not sure what temp they are supposed to run at,but mine has been almost to hot to keep your hand on the outside rear center section after a drive of 30 to 40 miles. Talked to a line mechanic at the local Ford dealership and he said that was normal,then went to my dad's house one day after he came home from town and had only driven his F-150 about ten miles and his completely stock 9" was about the same temp as mine,so I guess that is normal.

Have heard from others that they may get as hot as 300 degrees depending on how you drive....
