Refreshing front suspension in a 00 LX470. Was planning on doing Freedom OR UCAs and replacing lower ball joints with 555 sankeis. I was under the impression the you couldn’t replace ball joints in OEM UCAs but see a 555 sankei kit for them on cruiser teq. Anyone installed these in the uppers? Worked well? How difficult was it? Also advice on steering rack? Have a small leak and wondering if best to replace or try and flush and add AT205 or something similar, heard AT205 can turn it into a solid steering axle lol
