Based on everything I've found online I think your right, just wanted some confirmation before attempting to open it up. Is it a difficult repair to do myself? Do i need special tools like a press? What's the repair cost on something like this if i have to take the cylinder in for a rebuild? Also how much bend can a cylinder rod have and still work properly? It's about 99% straight but putting a straight edge on it does show maybe between 1/32 and 1/16 of a difference across the length of it but i can't imagine that small of a difference would cause the sticking. I guess I'll start researching cylinder rebuilds. Thank you.
