Is This a Door Latch Problem?

On my '67 driver's door, the inside handle must be raised nearly to the top of its travel before the latch will "pop open". The outside button works just fine and the lock, key and button, also works perfectly. Is this a worn latch problem or could the previous owner have used a rod that's a little too long when he built the car? He did a frame-off on the car, so I don't think it's a dirt and old grease thing. I'm wondering if the part of the latch activated by the inside handle could be worn while the rest is OK. It works well except that the handle has to be lifted so high. Any thoughts? Thank you.

Re: Is This a Door Latch Problem?

I had the same problem on my 70. I took the door panel off and lubed the mechanism and it opens easy now without having to lift the handle to the end of it's travel.

Thanks, Mike. I never would have thought a little lubrication would do it. I'll try that. What's good to use: WD-40, White Lithium spray grease, dry lock spray,...?

I just used WD40. I was surprised it worked to.

A good lubricant is Tri Flow. It has PTFE in it, so it will lubricate better. It is also what a local locksmith recommends for lubricating locks.

Hopefully it will help your issue. My '71 does the same thing - even after installing a different latch assembly. I suspect it has something to do with the rods and their attachment points after 48 years.

Also check to be sure the door alignment is proper. If it is sagging/dragging on the door jamb pin it will be difficult to open from inside yet easy from the outside. All about leverage.

Re: Is This a Door Latch Problem?

I've repaired and restored the latch assemblies for my '64. I enjoy diagnostics. Your assembly is OK. I lean toward a bent rod. However, there is a chance the part that the handle operates is 'not quite right'. Wrong part? Offset mounting? Crud that affects travel? Last resort - reset the handle a little lower. :-)

Re: Is This a Door Latch Problem?

Thanks, Roy. I should have some time tomorrow to pull the door panel and have a look. When you say "reset the handle a little lower", I assume you mean reset it on the shaft to, say, point to 4:00 or 5:00 instead of 3:00?

Re: Is This a Door Latch Problem?

Assuming original parts, this sounds like 'lost motion' due to worn parts. A bent connecting rod would open sooner in the handle's travel, not later; it acts like a shorter rod.

You probably have wear in a few places & that cumulatively is resulting in a lot of travel at the 'end of the road', which is the door handle.
Shortening the rod or bending it is probably the easiest fix.

Didn't get to it yet. I'm hoping today with a little luck.
