hey guys not sure it anyone has posted this yet but i did my air con tensioner bearing today it was squealing something chronic! the bearing to replace is a 6301
just press in and press out
to get to it i took the fan out, undid the pulley and took it out, then i loosened off the tensioner and did the bearing
put the pulley back on and tensioner the belt locked it off and fan back on easy as that.
any questions fire away
nissan wanted $132 for the pulley and that was with trade discount! spent $4.60 on a bearing and fixed!
