hey ya'll im a newb in the yota world but recently bought an 87 4runner with a straight axle out of an 84 the hubs have always been stiff when being engaged but yesterday my front end started making an awful noise almost like the ''train track'' sound of a bad wheel bearing and the face of the passenger side hub will rotate 360 degrees continuosly instead of the usual 90 from locked to free and theres metal shavings/chunks in my hub grease the previous owner supposedly just did the wheel bearings and it still locks into 4 no matter what way i turn the passenger hub any ideas what i should start with money is tight and id rather not go throwing money at it any help is greatly appreciated.
