here goes. front wheel bearings on the rio are prone to failure.
the OEM bearings fail because of poor lubrication. Aftermarket bearings fail because of improper installation.
you NEED the special service tool to properly preload the front bearings. you will need to buy new preload spacers from the dealer. they should have many many sizes in stock.
you dont need any special tools to remove or install the inner and outer races in the knuckle. a press is handy to remove the outer bearing cone from the hub.
the wheel bearings are two pieces, inner and outer, and they are both the same part number. you should also change the inner and outer seals, they are different part numbers. buy yourself some good synthetic NLGI #2 grease, it will help prolong the life of your bearings if you dont use the special service tool.
any of the aftermarket bearings are good enough, SKF, FAG, Timken, etc.. the OEM bearings are KBC, also fine if lubricated properly.
again, beg, borrow or steal the special service tool from the dealership. otherwise, no matter which grease of bearing manufacturer you use they will fail in short order. guaranteed.
