On my DT 18–135 mm F3.5–5.6 SAM I have to squeeze the ring tightly to operate the zoom. If not, the outside ring just spins freely around barrel. Is this failed adhesive or just loosening of the material? Any suggestions to fix? Thanks.

Over time the rubber material stretches or loses elasticity. I've heard of people using their own adhesive (rubber cement, super glue, other adhesives) to get some "grippiness" back.

This service manual for the SAL18135 lens says the rubber zoom ring part # is 4-294-835-01. There also appears to be a rubber focus ring (part # 4-294-796-01).

If you're in the USA, Sony's official parts supplier is Encompass. Encompass says "This item is currently out of stock. 10/26/2021 or 6 days" for both parts (example). This doesn't sound good.

You can also try searching eBay for the part numbers. I did a brief search and didn't have much luck.
