dewalt dc759 drill chuck wobbles its drill bits

[davidraz]

I need some advice on my dewalt dc759 drill. Originally my bits in the chuck have had a bad wobble to them. I purchased a new transmission/clutch assembly and new chuck. I still have a wobble off the chuck when I put in a drill bit. Is there anything else that can cause this.
Thanks

You can check the screw inside the chuck,maybe that had move out a bit and is causing the bits to wobble.

just a thought

It has the wobble coming from the gear box. I have the drill opened up and running it without the chuck on and see the wobble when I screw the chuck screw in with out the chuck. Help
