start by touching them with a wrench, check for loosening.
Rock the sidecar back and forth, jump up and down on it see if anything moves.
physically inspect components and fasteners for signs of failure. cracked paint or rust lines often indicate a crack in the underlying metal.
try to cause the noise by rolling the bike around, turning the handle bars, rocking, it etc-see if youcan isolate where the sound is coming from.
Shigeo,
Many years ago when I was a bridge painter, an old Railroad inspector showed me how he tested for loose rivets and bolts by rapping them with a silver dollar. If it gave a "ping" they passed. If a "clack" or a dull sound was emitted the connection would fail the inspection.
This same test can be applied to welded or bolted connections using a small end wrench (if you don't have a pre 1965 silver dollar).
A disclaimer here: It won't work on heim joints or rubber bushed connections. He just used it for steel to steel connections.

Finally went out for test drive.
Prior to this, I tightened front end bolts/nuts and re-adjusted the alignment.
The squeak is still there..
Also I experienced wobble @ 20~30 MPH slight right turn.
I held on to the bar but that didn't stop it.
I just didn't feel confortable so aborted the run.
After that, I looked at the mounts, pinged the bolts with small wrench but couldn't tell the difference.
Can be a metal fatigue and dangerous?
Should I replace all the mounts with new ones?
I know at least one of the u-shaped bracket has holes distorted badly. It's elongated so maybe PO overtighten the clamp bolt..
I didn't think of it much when I attached it but..
Or am I worrying too much?
is there shiny metal by or on the bracket with the elongated holes indicating it has been moving? Hard to second guess over the internet. If you are near a sidecar shop such as Doug Bingham, you might have someone else help you check it over...
If the holes in the U-clamp strap are obviously elongated, the Eye bolt has been overtightened and strap is not fit for use. A new U-clamp assembly should be used. At least a new strap is in order and I would also check the condition of the through bolts. On used cars sometimes I've found the 8.8 grade bolts have been replaced with softer 5.5 grade metrics or even ungraded 1/4" NC bolts.

Hi Lonnie,
Where can I get a mounting kit?
From VelorexUSA in NY?
Or from you?
How much would it (complete set) cost?
Shigeo,
I sent you a private message.

Got new mounting brackets from Lonnie.
Installed them today. There was no sign of old bracket moving.
Did the test drive in the parking lot. Squeak is still there but it seems to be from the disk brake itself.. duh..
Well, new brackets give me peace of mind.
Went out to the twisties.
I got wobbles getting out of right hander especially if I try hard.
Front forks twisting/flexing?
I should really look for that fork brace...
