[TR] TR4 door check strap repair

[Jay Holekamp]

The problem I've encountered is the 'anchor' portion of the check strap on the
door 
itself. It is distorted and almost torn free from the door.

 
Greetings
Jeffrey,
 
This is a fairly common problem caused by wear - this area on my
TR4 driver's side door was repaired last winter, as well as the associated
often-seen vertical crease caused by over-opening the door when the check
strap becomes completely nonfunctional (seperated). Here's what was done:
Remove door from the car and disassemble the interior handles and panel.  Now
you can see the inside of the check strap lugs (on the inside leading edge of
the door)  You'll see a rib with 2 tabs which are spot-welded to the inside of
the leading edge of the door.  The 2 lugs that extend beyond the leading edge
of the door and receive the pin and check strap are extensions of the rib.  We
tried to drill out the spot-welds with no success. We ended up cutting 2 slots
in the leading edge of the door and fitting a new strip of steel, in a u shape
around the rib and extending out thorough the 2 slots. The ends of the new
piece were shaped into lugs w/ holes to take the pin and check strap.  The
area was MIG welded up, ground / filed, cleaned up, primed and painted. The
door skin crimp was flattened, skimmed, flatted, primed and painted to remove
the vertical crease. I think the new door check strap lugs will last at least
another 40 years.
 
This procedure should be relevant to the same area on
TR4A, TR250, TR5, TR6, at least.  Let me know if this is unclear - likely I
fear - and I'll try to clarify.

brgds, Jay
