Front spring shackle sleeve

[texas69truck]

I hope the title makes sense. The PO somehow removed the two front sleeves on the frame rail. I cannot get the new sleeve back in. The d/s one went in great after sticking the sleeve in the freezer. The p/s isnt so lucky. I have tried freezing it, pressing it, hitting it, lubing it...nothing has worked! It will go in about 3 quarters of the way and then will not budge. I tried installing it the other way (inside to outside of frame rail) and it will not even get started. My line of thought is the PO heated the frame to get it out and it is now tweaked. Really dont want to heat everything up but it looks like this may be my only option. anyone else run into this problem or have any tricks/tips I havent tried?!
