They make a special tool to help remove the inner TRE. It comes with a set of crow'* feet and a long hollow tube with a couple slots for the crows feet and a hole for a 1/2" ratchet/breaker bar on the other end. The tool looks like this
Steps to remove inner TRE:
- Remove outer TRE from spindle and unthread it off of inner tie rod. When you unthread the outer TRE, take note of how many turns it takes to remove it. You'll want to know this when you reinstall outer TRE to maintain aproximate alignment.
- Cut both the clamps for the inner TRE boot (probably the hardest part of the whole job)
- Remove inner boot
- Take special tool mentioned above and find the correct crows foot for the inner end of the rod, then slide the tube over the rod and secure the crows foot into the tube.
- Use your 1/2 bar or ratchet to loosen the tie rod
- Remove inner tie rod.
Reverse to install. If the inner boot is torn, replace it. If the new inner tie rod end didn't come with any clamps, using radiator clamps is okay. The boot IS required, don't leave it off because it'll make the job easier.
