Topic: Chirping and slight lock up on front wheel

[metric-wrench]

Hey friends,
I have a strange thing happening, which I personally have never felt.
When I hit a bump significant enough there is a sharp chirping and a binding (almost locking) on the front wheel.
I checked the front brake pads... seems in order.  Also front brake is working fine (as fine as a stock cb750 brake works).
Is this my wheel bearing?  Can one wear so badly that it could cause this to happen?
Anyone had this happen to them?

Thanks in advance.

If the bearing is wobbly it could conceivably allow the wheel to move enough for the rotor to jam against the brake pads, or possibly a little sideways movement in the wheel possibly caused by a loose axel nut.  Both of these should be noticable in the handling of the bike, to check lift the bike onto the centre stand get someone to push down on the back of the bike or jack the front up to get the front wheel off the ground then give the front wheel a good wriggling and see if there is any unusual movement, the only movement should be the wheel turning on the axel.

Check your triple trees too. make sure nothing is loose or cracked.
