Broken Trunk Latch. Any suggestions on a fix?

Post by rickdf »



Hi All,

Not sure how it happened but just noticed the latch to my trunk is broken.
The other latch is still good but one of the "teeth" in the slot it goes into is broken, doh! So it won't lock now.
Any thoughts if this can be fixed? Thanks!

Fortunately, it's ABS, so it's easily fixed.

Clean up both the broken piece, and the area it fits with some rubbing alcohol. Then make up some ABS slurry (ABS shavings and ABS cement) and slather it around the inside of the trunk lid where that piece will fit.

Liberally coat the broken piece with slurry, then put a decent coat of ABS cement along all the broken edges. Fit the piece back to where it came from, and hold it in place until it solidifies enough to hold itself - it shouldn't take long.

Once done and cured (overnight, to be safe), I'd probably mix up another small batch of slurry and smear it over top of the area that cracked, to add reinforcement. Let that cure as well.

Great idea. I thought about gluing with like epoxy but didn't think it would be strong enough. Your method definitely sounds much better. When you talk about making ABS shavings, what exactly are you talking about? Just like a sheet of ABS that I can buy at like Home Depot and grate it up using a rasp or cheese grater? Thanks!

You got it! I find the quickest/easiest way to get the shavings is to take a large drill bit and drill holes in the ABS. The drill shavings are quite thin, and "melt" in the solvent very quickly to form the slurry.

You'll see a fairly good discussion on this procedure with lots of pictures here: viewtopic.php?t=35675

Don't know how your's got busted …
... but I've seen folks just drop or slam the trunk down.

I ease it down to where the latches just start to engage, then just reach forward to pass seat back rest top and pull, it clicks shut.

Slurry idea above is the way to a fix short of replacement.

You can still buy ABS cement on Amazon. GP cleaner can be used before using the glue. It holds very well on properly cleaned pieces.

Yeah, I'm sure I either dropped it or slammed it too hard at some point. I'll definately have to be more careful in the future. Thanks!

I see it's available at my local Lowes. I'll probably pick some up tomorrow after work. Regarding the GP cleaner. I don't see that available local so do you think denatured or isopropyl alcohol will work as well? Thanks!

Not to hijack the thread, but the OP also mentioned the latch that engages the hooks on the lid was broken on the other side so with broken hook on one side and broken latch on the other could not lock.

I too have broken latch on one side, the hooks on the lid are both OK.

I haven't opened up the latching mechanism yet to see what broke, are those parts even available? Are they ABS too? I wouldn't mind having both sides of the trunk lid able to latch, and I'm sure the OP would like that too....

Yes, I've put that on the back burner for now, but at some point, I'll have to address that. The catch assembly (#42) is the part that I think needs to be replaced. It's not too bad cost-wise and still available via Partszilla (below) so that's good news. I'm going take it apart at some point to see if it's actually broken or if something is just stuck.

Here is some info that might be a fix for both of you on the trunk latches. One is an email address of a guy who used to, and possibly still does, make some metal ones to replace the plastic ones that Honda put there.

Here is a link to how Mr Magic Fingers fixed his broken latches.

Forum member Moto_Man makes the metal latches, he wrote about them here: viewtopic.php?t=21279#p118415

I bought a set from him and installed them in my GL1500, they work perfectly, and will never break again.

Here's what they look like:

Doesn't look like he's signed on since 2014, wonder if he's still around.....

Lowe's will have general purpose plumbing cleaner. Oatey Clear Cleaner is one. It has a high acetone content and not only cleans well but etches (and slightly softens) in preparation for the glue. Don't get it on paint! Our big box stores around here stopped carrying ABS glue because ABS is frowned on by area plumbers I guess. I think it meets code, but here they just use PVC.

Just got it done following your method and it's looking pretty good. A little messy maybe but even after just a few hours it's feeling strong. I'm going to let it cure for another day before re-attaching the latch. Thanks much for the great instructions. Oh and for anyone wondering. I used an ABS toilet flange (Lowes didn't have any ABS sheets) for the source of ABS. I drilled two 1/2" holes and it gave me more than enough material for making the slurry. Cheers.

Once a plastic part is broke it is never as strong as original. Beef up around that repair with at least 2 more slurry layers.
