HOW HARD IS IT TO REPLACE BALL JOINTS ,

 

2WD is not too bad on most vehicles...4WD can be a HUGE job on some...major grunt work and you may need access to a torch and an air chisel.

BTW...posting in all caps is like yelling at someone

 

it all depends. some cars have ball joints pressed into control arms, some have them bolted in. obviously, the 2nd one is easier to replace.

on 4wd, you'll have to remove halfshaft to get to lower ball joints(at least, from the hub). control arm usually needs to be removed.

you have 2 choices:

oversized deep socket and sledge hammer to hammer them out and press new one in(done it, but takes some finess and know how to do it right, or you may end up with ball joint sitting crooked in the seat);
or, remove control arm and bring it to any local tire shop that will press old ones out and put new ones in, as they have press for that. how much - don't know, but you definitely want to call around. if they do it ALL for you, you may end up with $400 per side. and if you really look at it, the part is anywhere between 16 and 30 bucks, and it is not that much mechanically complexed to do, unless your manufacturer did its best to make it DIY impossible.

PS go to local library, pull chilton off the shelf, and read how to. that should give you some insight.

if not your exact model, surf the site and you'll find it.

 

if you do it your self get an alignment afterword as it will probably (definatly) need it.
