I’ve got a vibaration from upfront which if I “bounce” the front wheel appears to be the wheel end of my fork – Reba 29 120mm.

I’ve checked the headset etc but can locate another source and it makes the front feel “loose” when riding.

Is this common/happening to others?

How old are they, what you describe is worn bushings.

I had something on mine and I was being a muppet and my QR wasn’t quite tight enough…. 😳

Assume you’ve checked rotor, brake calliper and the other obvious tighten-able bits?

They are 2016’s 4 rides old. They are 15mm bolt through done up tight with a screw in Mt Zoom bolt. Same effect with a RS Maxle.

Wheel bearings shot?

Nope, fine on the other bike, 100mm Reba on that one.

Fork Bushing have play, otherwise they wouldnt slide. You need to take it to a shop to get someone who knows whats right to tell you if its acceptable or faulty.
