Username Post: 93 C1500 door rattle question        (Topic#356649)

I have a 93 C1500 suburban.
The passenger side front door rattles like crazy and is driving me crazy. The hinges are ok on that door.
The drivers side front door hinges are shot and but doesn’t rattle. The rubber bumpers look same on both doors.

I assume it has to be lock mechanism but I can’t see what’s wrong with it. The closing latch, when closed, seems to have the same amount of play as the quiet doors.

Just looking for confirmation and/or explanation that it’s the lock before buying one. Or where else to look?

Thanks

If the whole door is rattling up and down, the hinge bushings are likely beginning to wear. The door may look straight when it's closed but the striker causes it to ride up when it's shut. They generally only look sagged in the closed position when the wear is heavy.

Try opening the door just a few inches and grab it from the rear pillar, window open, bottom of the window opening. Try moving it up/down. Move the door a little bit open/closed as you do this and see if you get movement up/down, as the hinge design may keep it in check until it's in the right position.

Your driver door probably isn't rattling because it's sagging enough to keep tension against the striker. Check the striker for wear marks and the latch as well.

The strikers are adjustable to a degree but if the door is shut flush then adjusting the striker isn't the fix.

Wild guesses without being able to see it in person, but you can inspect both sides and let us know.

Thanks for suggestions.
I can't find any play in the passenger side door hinges - up/down or attempting to twist it. Door closes with a slight feel of hinge onto the door lock post. I can see a pretty small wear mark on the larger diameter part which I assume is the guide and the smaller diameter part of post is where the latch closes. net - it seems pretty good from alignment and hinge play POV. It seems the play is in/out & not up down but that's hard to be sure by manually trying to force the door around by closed. I measured the OD of where latch catches and it's not much different than where latch doesn't hit so it doesn't seem excessively worn.

The driver's side door is really loose on hinges and there is a big wear mark on top of the door post where it's sliding when closing. So, like you said - maybe it's just dragging/sitting down so hard it's not something to compare.

Two 2nd seat doors are similar to passengers side - but maybe a little less in/out play when closed. Both are quiet when driving.

All 4 latches seem to have same amount of play in locked position.

So now I'm wondering about loosening up the latch and attempting to move it a bit towards outside of passenger door. Not sure how it would have moved or shifted over time. I don't remember when the noise started. My kids drove it thru high school and then it sat for years until I started resurrecting it as camping/lumber yard truck. So no help on an specific event causing the noise. Of course - no telling what the kids did with it..

Update: found its not possible to move the latch in door

Yep, the latch doesn't move. The striker is adjustable, but it's tricky to get it right. Loosen it only slightly, as the nut plate behind it in the pillar is not attached to the body and will fall off if you remove the striker, requiring interior panel disassembly to get it back in place. Not fun.

You can loosen the striker just a little, tighten it back down just barely snug so it can move under force, close the door carefully, then open it as gently as you can to not disturb the striker's new position - then tighten it down. Trial and error, and patience, win the day here.

Thanks for advice.
I looked at the post and it doesn’t appear to have shifted - or the latch so it’s confusing that something would need to be moved to fix the noise.
I think I’ll wait until my girlfriend can drive while I sit in passenger seat and try to determine how it’s moving before I try another adjustment.
It may be a while but I’ll let you know what I eventually find.

May simply be that the weatherstrip has compressed enough that it can't keep the door from rattling. It's old...

This was the problem with my '93. I'd replaced hinge pins and bushings, then adjusted catch posts. That didn't help, then a heavy rain showed me the problem. Not a lot of leakage but just enough to see.

Thanks for suggestions and experiences. I think I’ll try the weatherstripping. It is 25 years old and has been in Arizona heat for all of that so can’t hurt to replace it. Will let you know

Bang on the door with it open and see if it rattles. If someone replaced the motor or regulator they may not have put the bolts back in.

Well, I replaced the weather stripping and that fixed the noise.

I also spent a bit more time looking to see if there were any differences in door lock mech between drivers and passengers (the side that rattled). I measured the latch as it would be when in latched position carefully with respect to the door frame. It turns out that the passenger side latch, moves about 1/8" further toward inside of door (ie - the door can move about 1/8" more "open"). So I guess that latch is worn a bit more and along with the 25 year old weather strip it had too much play and caused the rattle.
Regardless, it's quiet now! I'll replace the others when after I recover from the pita of replacing the passenger door.

Thanks all for the help and suggestions.
