Nikon 17-35mm f2.8d Stuck Zoom Repair

Like many of you watching this, I have a Nikon 17-35mm f2.8d with a sticky/stuck zoom. It was moderately sticky when I bought it for a song $360 ($1.951 as of the filming date on Amazon). I knew the risks - and within a week or so it stuck hard on 17mm. I've never been one to be scared to take something like this apart. With a full service at Nikon running around $300, I knew all I had to do was get it back together if I couldn't figure it out and send it in for a full rebuild. I was able to 80% disassemble it (no need to get into the focus motor mechanism) and reassemble successfully. The video is long, nothing I can do about that. And I did not have a camera operator to watch the focus so I apologize for the out of focus segments. It was the best I could do and hope this helps you if you decide to take this on yourself. Although I was able to free up the zoom I did not discover the cause of the remaining stickiness at 20mm. So at some point in the near future, I will likely send it to KEH or Camera Works in Durham for a full service. I bought this specifically to use 77mm filters on astro shots alongside the Rokinon 14mmf2.8. I hope to give that a go before I need to ship it off so that I can decide whether or not I will keep it. ** - UPDATE: I wound up sanding this to Peachtree Camera Repair in Marietta, GA for repair. Turns out the helicoid was bent. I can only suppose the previous owner dropped it? Does help me sleep at night knowing it was highly unlikely I would have found that issue. Side note - I was extremely satisfied with Peachtree and highly recommend them. https://www.peachtreecamerarepair.com/ As always, thanks for watching, and don't forget to subscribe - Vinny Follow my social media at:   / vincentsmith-114750010441530   https://parler.com/profile/GWHQAppari... https://mewe.com/i/vincentsmith22 If you have a sec check out my photography at   / vincentsmithphoto
