My $0.02, if you've got the original Timkens I would just clean, inspect, repack, reseal. If there are no obvious signs of damage (pitting, blue metal, flat rollers, surface roughness) you are better off repacking with high temp synthetic grease than you are taking a risk getting Chinese garbage bearings. Last set of wheel bearings I got for the '85 truck were nice and expensive and came in the signature black and orange Timken box. Under the part number on the back flap of the box it said "Country of Origin: China"
These were bought at a high quality parts store. I went back and demanded something else, got SKF bearings but they didn't fit, wrong part number. Went back again, got National bearings which had "Made in Mexico" on the box... better than nothing I guessed so I put them in. Got me down the road until I sold the truck.
Again, take this for what it's worth. Two cents...
