Pentax 17-70mm F4 focus problems

Hello and thanks to anyone who will give an advice on how to fix the following problem.
My lens was working very well until it one day(with a hood on it) it was jammed between my back and a bench. Now when I zoom in, at a certain point it is unable to focus. It tries but cannot. If I zoom out a little - it focuses. I start to zoom in in small steps, while half pressing the shutter release button and it may(not always) focus till the end. I know it is a mechanical problem because when another lens is attached it focuses at any zoom position. Does anyone know if I could disassemble the lens and repair it by myself? It is too expensive to send to another city with the body.

I had a problem with mine early on. It just suddenly changed and wouldn't zoom less than 28mm. Then I heard something rattelling around inside it. As it was under warranty it went to Pentax for repair. Been great ever since now more than 1.5 years later.

I have no idea if this could be self repaired, but I wouldn't mess with it if it was still under warranty. If not then there is the SDM system to consider. I think it's off to the shop.
