A Healey who done it?

This might sound weird but check the trunions on your brake and clutch
pedals that they are not worn or that the holes in the pedal levers have not

Check that the front wing bolts under the R&L posts are not loose as well as
insure the shroud to wing bolts are all tight.  Some of these are so hard to
get to they sometimes don't get fully tightened even by the best of

If any of these type of fasteners are loose their knocks echo and travel
seemingly "throwing a voice" or "sound traveling".

Both of the above had me inspecting front end components since finding just
where the sound was coming from was impossible.

Have the shock towers ever been replaced?

Did you drop tools down the frames "black holes" that might clink, clunk?

Brake pads and shoes sometimes move and clunk within their beds when
direction or pressure is applied.

Don't give up.  I bet it is a washer or other finger tight fastener that
moves about and echoes down the chassis rails.

hate to admit defeat, but cannot seem to find source of knocking in front
of bj8.  whenever the car is moving and brakes are applied, i hear a knock
from the drivers side and sometimes on pax side also.  since i also hear the
knock when rolling down the driveway at an angle to the curb, with or
motor running and the brake pedal no depressed, i have eliminated brakes and
motor mounts.  i have pulled both steering gear and idler, new bearings and
bushings, seals, etc., and adjusted out all slack.  checked tie rod ends and
cross arms and end joints appear very tight and well greased.  removed sway
bar and no change.  pulled the big nuts off bottom off king pins and they
in excellent condition.  no slack in king pins, laterally or vertically.
shocks are as tight as i can get them without stripping.  no play in wheel
bearings and hubs are super tight.   since it appears to be coming from
part of suspension, as confirmed with another healey owner, does anyone have
any idea what i might be missing in my search.    hjim
