Its usally pretty cheap to have the rods resized and straighten at the machine shop maybe best to take them in and see if that was the problem.
Also do the bearings have an .010 or .020 on the back of them. They may also say std. If they are stock rod bearings and the rods are larger than stock the bearings will fit loose. They should have no gaps in between the beraing with the cap on and on the pin. If there is any space they are the wrong size.
They also can get weak when they wear oit and not fit as well. Best to get everything mearsured out.
