>How big a pain in the *** is installing new Ball Joints?
That depends on the size of the *** you are using as a benchmark !
>Whats all involved?
If you are just doing the upper's it's not all that bad. After the spindle is free of the upper ball joint, an angle grinder on the rivits will get you close. Then a NEW drill bit will make short work of the rest of the removal.
If you are doing the lowers'. The old ball joints will need to be pressed out, and the new ones pressed in. You can check out your local tool rentals to see if they have a ball joint press that could allow you to replace them yourself, and maybe without the a-arms being removed.
Usually it requires removal of the lower a-arm and handing it over to a machine shop.
>And when I do that (since everything else except tie rods is >original) should I go ahead and replace anything else?
Check the a-arm for excessive movement of the cross shaft and bushing for cracking and general dryness. It's a good time to do the idler arm too.
If you do ball joints and bushings you will not believe the difference. It will be like a brand new truck.
ALSO; Make sure you have the front end aligned when done.
