You're absolutely right—it shouldnt be a hammer fest to get the front axle in and out on your bike. The axle should slide in smoothly with minimal resistance, typically requiring only gentle persuasion.
Possible Causes of Your Issue:
- Slightly Bent Axle – Even a small bend can cause significant resistance. Roll it on a flat surface (like glass or a granite countertop) to check for wobbling.
- Misaligned Forks – If the forks are not perfectly aligned, they can create binding. Try loosening the fork pinch bolts and the lower triple clamp, then realign before tightening.
- New Bearings Not Seated Properly – If the new bearings are slightly misaligned or not fully seated, they can alter the spacing.
- Axle or Fork Tube Corrosion/Debris – Even minor dirt, corrosion, or burrs on the axle or inside the wheel hub can cause interference. Clean everything thoroughly and lightly grease the axle.
- Spacer Issue – If the internal wheel spacer shifted during the bearing replacement, it might not be lining up properly.
What to Do:
- Check Axle Straightness: Roll it on a flat surface to see if it's bent.
- Inspect Fork Alignment: Loosen the fork pinch bolts, insert the axle (without forcing it), and see if it slides in easier before tightening everything back up.
- Ensure Bearings Are Fully Seated: Double-check that they’re pressed in correctly and flush.
- Clean & Lubricate: Clean the axle and apply a thin coat of grease to help smooth insertion.
- Check the Wheel Spacer: Make sure it’s properly in place and hasn’t shifted.
If you confirm the axle is bent, replacing it is the safest option. Let me know if you need help troubleshooting further!
