In 6 months time many HTC Touch Pro/ Fuze owners are going to start having loose keyboards, and some intrepid owners will be looking at tightening the rails up themselves.
For these adventurous types the HTC Raphael Service manual may be of great use, as it describes in great detail how to disassemble the Touch Pro safely (and believe me, it looks pretty tricky).
The manual is presently available to download from HTCwinmobile here. Get it quick, because who knows how long it will last.
