I think 0.025" of waggle is lots! After more than 2 decades of use, maybe it deserves a make-over.
There is not a lot else that can move anywhere sideways except the middle of bearings relative to their outside races.
Take it apart. Go after the bearings.
Then also start getting picky about the chuck condition. If the chuck is spinning without any bad run-out, but the drill rod it is holding does have run-out, the chuck jaws may need some help - or just replace it with a nice keyless type.
At this point I've pretty much decided that a bearing replacement is in it's future. As far as the chuck goes, I've already replaced it with a good
one. The chuck that came with this DP wasn't worth the steel it was made from.
This one is a Jacobs Precision Chuck: sort of their version of an Albrecht I think. Chinese made, but with a guaranteed TIR of .0016
or better. I believe it since every time I've put an indicator on it it's barely twitched the needle. It has been an excellent chuck.
