Lower ball joints

[MASTERBrian]

Had my 2012 Yukon xl Denali awd in the shop for an oil change.

They mentioned the lower ball joints on both sides are a little loose and recommended to keep eye on then. This was at the dealership I purchased it from last year. On ther way home I stopped at another shop I use on occasion and asked what he charges to do the work. He said these newer trucks are horrible when the joints start to go bad and why soo many have wheels fall off. He also mentioned to replace they aren't typically press out any liner you have to replace the control arm as well.

When I got home I crawled under and took a look. Hard to see if pressed or not, but removing the arm doesn't look too bad. Does it really need replaced in the awd Denali? How bad of a job is it for the average shade tree guy? Ie any special tools, etc.? It appears 2 bolts to frame, the strut, remove from spindle and possibly pull the axle to gain room.

They also mentioned a wheel bearing on passenger side as well, so guessing that's the time to do the job.

I've looked and most kits do include the spindle with the ball joint. Im assuming alignment is needed after, so should I replace the uppers ar same time?
