new owner f250
 

Hi all, I just bought a 2006 F250, 6.0l diesel here in canada but for safety inspection it needs upper ball joints, one outer U-joint, brakes and few other things.... nothing really major... after doing some reading, I should remove the knuckle to get to the upper ball joints, so I might as well replace the lowers... the struts are ok but not great, Im gonna replace them ... if m pulling out the shaft to replace one U-joint, should I just replace the other side as well? and while Im there, is there anything else I should look at and/or replace?
also, one of the rear calipers is leaking and needs to be replaced, I hate to do only one side but I cant seem to find a 'reasonable' price for the pair.. any good source?
