I have not pressed out the bushings on an 2500HD LCA , however IMO a ball joint press (BJP) should still work as from what I can tell the 2500 LCA is nearly the same.
On 2500 LCAs it took less than 5 minutes per bushing to press them out using a BJP. (I had taken the LCAs to a shop for them to do it with their hydraulic press and they could not do it as they could not get the LCA set up within the opening - so I brought them back to my garage and pressed them out with the rental tool I already had for doing the ball joints).
