How do these come off. One person said they are bolt in style just got to get the rivets out, another person says they are just press in. What about the lower ones? If I am doing the uppers maybe I should do the lowers also.

Thanks

 

I don't know about a '99 but my 2001 2wd has both upper and lower ball joints riveted in. My understanding is that you grind or cut the rivet heads off and the new ball joints get bolted on. I THINK that only the 4wd are pressed in. My boots are broken on mine and soon I will replacing my joints. So - I will soon find out.

 

on my 99 sport they were press in press out you definatly need a press my uppers went in fine but my lowers were a pain in the **** they were 45,000 of an inch to big i had to drum sand my lower c.arm so that it was about 10-15k of an inch to small then press them in i would suggest doin em all if ur doin the uppers u might as well that way they are all done....j
