well, its all about having the right tools, i did all 4 ball joints in about 4 hours, without a torch it would have been much longer. and i had prevoisly had the spindles out of the knuckles, so they didnt come out as bad as they did the first time, the first time i had the spindles out, it was alot of hammering with a dead-blow hammer to get them free of the knuckles. when you hand pack wheel bearings, you know your there when you get grease out the other side. there is a neat tool that you put the bearing in and hook up a grease gun to do it with, i dont have one, so it takes about 5 min per bearing to pack. you might as well do the upper ball joints as well while youre there. a press helps get things back together. be sure to get replacement joints with grease fittings. then with proper maintenence, you should never have to change them again. you will probly need a alignment afterwards, mine need one before i even replaced my ball joints, so i didnt wait long before getting one after i repaced the ball joints. was about $100 locally, money well spent considering how it affects handleing and tire wear.
