So, I have a stuck lock nut on one side of my front axle, and I can't seem to get the axle out pushing on the other side. I need some pointers on diagnosing and repairing this.
The bike is a Merida Speeder 300, and the product page lists the hub as "Bearing disc". The bearings are cartridge bearings, which means this answer doesn't help.
Here's a shot of the stuck nut:
I believe the cause of my troubles is that those outward-facing ruffles have been tightening the nut.
The other side looks like this:
There's nothing on the axle where a wrench could find purchase.
The nut and assorted washers that came off are these:
The other side of the nut is flat. Only the nut is threaded, and it's the only one that has flat sides for a wrench to grip.
What I have tried so far is to grip the free end with a pair of pliers, but I didn't get a good enough grip to get the other nut loose. I have tried to push the axle out from the free end, including whacking it with a rubber mallet a few times, and I even tried to put my weight on the hub with the free end resting against the ground. The axle hasn't budged at all, as far as I can tell, and I'd at least like to have a second opinion before I try to hammer the axis harder than I already have.
