The bearings can come complete with the hub but unless you get a knuckle they arent bolt in.The old ones like he has are press.My nephew had an old caravan and both were bad.It would shake like a bad tire.They were real bad.He got 2 knuckles at the bone yard for like 40 bucks.It was a beater that he took hunting and didnt want to spend the $$$ for new ones.Rocky
