Are you using their Polygrafite bushing kit or their OEM rubber kit? If you (I hope) are using the Polygrafite kit....take the grease they give you and smear it on the bushing...then push the bushing into the control arm shell.....then take the bolt sleeve and smack it in through the center opening of the bushing with a soft face mallet/hammer. If it's the rubber kit, I can't help ya'. I don't use rubber's. Pardon the pun.
Sarge Hope this helps!
