Bicycles Asked by Žilvinas Rudžionis on July 21, 2021
After the crash I straightened back wheel, and cleaned and lubricated the chain, but now spinning the wheel causes sound as if there is something wrong with bearings.
Here is the video: https://streamable.com/fhb81d.
My bicycle model is Trek Domane AL2. What might be wrong with the bicycle? Should I try to disassemble the bearings and regrease them?

Went to bicycle shop. Confirmed that degreaser got into the bearings.
If the wheel was impacted enough to require truing it’s plausible the hub was damaged. The axle might have been bent, bearings damaged or the freehub mechanism.
You can easily check for bearing problems. Take the wheel out, turn the axle manually. Feel for play or roughness in the bearings as the axle turns.
Hold the axle ends and spin the wheel, check for clicking or grinding noises. Hold the cassette and spin the wheel backwards, check for clicking coming from the freehub mechanism.
The nuts on the axle indicate you may have a cup and cone style hub which can be disassembled. I’d hesitate to disassemble a rear hub though as the bearing arrangements can be complicated.
