Yes. Remove the bottom cap of your toothbrush. (Plenty of videos on YouTube that will show you how) I used the smallest and thinnest flathead screwdriver I could find, slipped it in between the case and the cap and it came off with minimal damge. Then there are two plastic clips inside the case that need to be pushed back in order for the internals to be pulled out. Once the clips are pushed back place the metalic shaft on a hard surface and slowly push down onto the surface and the internals will slide out of the case. Once out you will notice either the screw is lose, or the bolt where the screw secures the shaft to the internals has broken off. If its lose, just tighten the screw and you're good to go. If it's broken off, just go to Amazon.com and type: Metal Shaft for Diamond Sonic Care Toothbrush and you will find a replacement part for under $25.00. It's just that simple. Be careful removing the water proof rubber sealants on the old shaft. You're gonna need to put them on the new shaft. If you break them during the removal process, you can find replacement ones on Ebay for under $5.00. Good Luck!

I’m so annoyed with Philips. This toothbrush cost me a small fortune. The metal shaft came out with the toothbrush head when replacing it. There’s absolutely no way of getting this toothbrush open without damaging it despite what has been written above. Look at the YouTube videos and you will see that they’ve destroyed the metal end cap and/or rubber seal in the process of opening it. I can’t believe a toothbrush that costs this much can just fall apart. The best resolution to this issue is to buy Braun. Never had a Braun fall apart on me and also the toothbrush heads never made that ridiculous loud noise that some of them randomly make, even brand new ones.
Brauns do break! My Oral B Pro 3 3000 was less than 3 months old when the brush head became very loose. The tip of the metal drive shaft had broken off and was lodged inside the brush head. It went back to Braun under the warranty and it was returned repaired more than a month later. I had by then bought another electric toothbrush - a Philips which is more effective and quieter. I sold the Braun on eBay for half what it cost me but I'm much happier with the Philips.
