Do the rear bushings with special tool
Rear integral links, ball joints, thrust and control arms.
FCPeuro has the parts
Get the Pelican Parts Ball joint press and the ebay and amazon ones hare very hit or miss and if you have it apart, will take a while to get a press. Can't use a rental press due to flat side of press. Easy with airbladder. I would convert to spring but up to you.
Get a laser four wheel alignment after. Remember to tighten control and thrust arms on the ground. I did mine with 258k miles. Everything was way nicer of a ride after. I did not need swing arm bushings.
