But i don't understood if you have replaced the autofocus motor or replaced the glass of lens.
I'd like replace the frontal glasses (where is the lens cap) of the two lenses...

Hello... Sorry for my english...
I have 2 lens 17-70mm Pentax F/4 SDM ... One of these have Autofocus broken... "dead autofocus"... and the rest all ok. The other lens works fine BUT have a "scratch" on frontal glass.
How can i dissassembly the two lens for replace the glass scratched with other glass "clean"?
I hope my translation is understandable
TIA

What I did I've changed auto focus motor instead of front element. You need to have some soldering skills as soldering will be required. I think it's gonna be hard to remove front element (front cap) if I would be in that situation I would go for auto focus motor change, not front lens.
Do you have any tutorial step by step to show me? (or photos, or sites..). For example for my phone or Mac i use "ifixit.com" where everything is explained step by step.
Hope that was clear enough if not will send you pm then you can reply to it
