sorry just back from my garage, could not find this old crap. I DEF needed to cut it on one side..was very bad..
It is one piece. Spray liberally with silicone and press it out in a vise. Put the new ones in the same way.
I just did this and I tried the vise however not wanting do damage the new bushing used my sons Harbor Freight press which worked great.
Thanks for the tips!
