so i just replaced my idler pulley bearings with nice skf bearings i got locally..when tight there is some slop in them.. i dont remember if they are all like that or if my spindles are slightly worn to make this happen.. also how tight is the nut on the back supposd to be? i put blue locktight on it and also used a new nut etc.... maybe i will put the brackets in a vise and give another little crank to them to see if they snug up? i dont really feel like spending almost 50 bucks for the spindles...Dave...
