Can you fix a stripped crank?
There are many ways that crank threads can become stripped, but by far the most common way is through cross-threading the pedal thread when installing the pedals. Thankfully if you have an aluminium crank, then cross-threaded cranks are easy to fix with a crank thread chaser.
Why is my crank wobbling?
Chainring wobble means the chainring and the chain are moving left and right in correlation to the frame. The chain is catching sprockets at a weird angle, increasing wear on both. The riding force is unevenly transferred from the chain through the spindle to the bottom bracket bearings due to wobble.
