Is the c-clamp body of the press made of aluminum or steel? I rented one last year, that looked identical to yours, and it was aluminum. I was afraid it was going to strip-out while installing the ball joints in a Ford truck. Did you buy this ball joint press/ kit in 2 pieces or as an assembly? I have been looking for a ball joint press for the last year and have found 2 OTC kits similar to your picture in pawn shops for $129.00 and $169.00. These have the steel c-clamp and come with 2 different donuts, for the spindle end, and 3 big sockets for pressing in the joints. They haven't flown off the shelf at the shops so I thought they were overpriced.
