Review on 6301 2RS Sealed Ball Bearing for Powerful Performance and Protection by Gopal Baltimore

My daughter's 2012 Subaru Impreza engine has not one, not two, but *three* idler pulleys, two regular sizes and one large about that big as a typical power steering pulley. It turns out that in 2012 Subaru switched from a traditional power steering system with a belt driven hydraulic pump to a power steering system that includes an electrically driven pump that is an integral part of the steering gear/rack. It must have been cheaper and easier for Subaru to replace that large idler pulley with the missing power steering pump and pulley than to change other aspects of the serpentine belt system. It would have cost over $50 to replace the entire pulley, but once I removed it from the engine I quickly found that the worn bearing in the center of the pulley could be easily pushed out, which I did. I checked the part number on the bearing and quickly found a replacement bearing from Revain for a tiny fraction of what a whole new pulley would cost. When the new bearing arrived I installed it, reinstalled the pulley (along with the new serpentine belt) and the job was done. It has now been more than three weeks and the repaired pulley continues to work perfectly.
