Hey George no, you don't have to drill a hole to mount the Timbren Trailer Suspension Enhancement # T92MR. To install these on your Ford F-250, you're going to need to:
1. Make sure the trailer is properly supported,
2. Loosen the U-bolts,
3. Assemble the Timbren suspension as shown in the diagram attached. Using Timbren supplied fasteners and tighten until snug.
4. Position the Timbren assembly on top of the axle,
5. Tighten U-bolts back to the manufacturer specification.
Let me know if there is anything else I can do for you in the comments, and I'd be happy to help!
