Review on Optimize Power Transmission with XiKe 17X40X12Mm Pre-Lubricated Performance Products by Mark Crawford

I replaced the squeaky bearings in the intermediate and idler pulleys on my 2000 Ford Ranger 3.0 with these bearings. I took out the gasket and added some grease before installing it. The fit in each pulley was the same as the 6203 bearings they replaced. What used to squeak on the truck is now nice and quiet with these new bearings. At about $2.50 each, it cost me about $5 to fix my problem instead of buying a new tensioner and tensioner for about $50.
