If you have all the parts, it doesn't matter if you do the lift or radiator first, but you'll replace the LBJs while you are installing the lift.
Remove old LBJ, install new suspension, install new LBJ. :beer:
2000 4runner, getting ready to put new LBJs, radiator, and OME 881/906 with Bilstein 5100s.
Is there any specific order that i should be removing/replacing parts to make things easier?
With LBJs being the weak spot on these rigs, if you don't know when they were replaced I would do the lift first. Unless your radiator is currently failing and you need to still drive it.
While you have the front disassembled might as well do tie rod ends, unless they've been done prior. you have to take them off the LBJ anyways.
