I have been trying to find a shop to press in my new bushings and a few have mentioned freezing the bushings for a few hours to allow for an easier insertion.Is this something any of you've done before installing them? I found an NTB9National Tire and Battery who has a screw press,t hat's a press with a kind of tall screw and a crank on top they say will do the job without touching the center parts.Should i freeze my bushings overnight before bringing the car to them?
