I just put mine on last weekend. The front end was already apart.
*Removing the downpipe helps (but isn't necessary) on the pass. side.
*GearWrench or ratcheting box (18mm) helps on both sides. It's tight on the driver's side with the steering column in the way.
*Have some tape or zip ties ready to secure and label the shims when you remove the old arms.
*You may have already read this elsewhere, but don't turn the bolt heads - just the locknuts. The bolts are serrated to fit into the frame, and once they turn freely, they're pretty much done. You can get around that with the tubular arms, but it's still a pain...
