Would this be the u joints? Squeaky to. Man I hate buying vehicles no one takes care of their ride

 

Also if so how hard is this to fix? Was told the ball joint is bad to.

 

there are u-joints in the front drive shaft that only turns in 4wd. its a double cardan thing.

if the big axle nut comes off easy then its not bad. if the big axle nut won't come off then it sucks.

ball joints are a job.
