Default 2000 OBS Rear Latch Rattle

Just picked up a 2000 OBS. I've been reading through the forum and learning a lot. Everything has been great with the car except for a loud rattle from the rear hatch latch whenever I hit any bump in the road.

I found an old thread in the tech archive that had some good ideas: "I had a similar rattle. It was caused by the rear hatch not shutting snugly, and it was easily fixed by adjusting the rear hatch latch. Repair time - ~15 minutes. Remove the plastic covering on the bottom of the back hatch opening (on the frame of the door, not the door itself) by removing the four plastic screw covers on either side of the bottom of the hatchway, then remove the screws holding the plastic cover. This exposes the adjusting bolt for the rear hatch latch. Loosen the bolt, and move the latch so that the door closes tightly, then retighten the latch. Reinstall the plastic covering. Done."

Sounded good. Taking everything apart I found that the latch had already been adjusted (moved in towards the car) as far at it could moved, so no help there. Tightened everything up but still have the rattle. I tried reversing the latch (won't shut), took apart the plastic cover on the door itself to see if anything was loose (all is tight). I had a dealer look at it last week during a 60Kservice and they said the problem was in the latching mechanism in the door itself. Supposedly, three plastic peices and one was broken--$250 to replace since the car has keyless entry. When I had everything apart today it all looked fine but I wasn't exactly sure which was supposed to be the broken piece.

Any suggestions/insights beyond turning up the stereo and reaching for the duct tape?

Thanks!

Find a latch assembly at the nearest junkyard. Latch from any pre-2002 impreza wagon (OBS, L, Brighton) should work. Older Legacy wagons may even have the same mechanism, I don't know. Maybe it's the lock that's loose, not the latch? Good luck.

Thanks for the reply. Lock/latch...I've been trying to figure out the correct terminology in looking through old posts but there's not much consistency.

Anyway, the actual hoop that attached to the car is solid, and the lock/latch in the door looks solid as well. The problem is that something is not as tight as it should be when the door is shut, and I get the rattling sound. I can crawl in the back and push on the closed door and get the same metallic sound. It looks like the hoop is what you adjust as noted in my earlier post but this appears to be adjusted as much as it can be adjusted.

The dealer may be correct that the problem is in the actual lock itself (which closes and locks fine), but $250 of correct to get them to fix it is not my ideal choice.

put some soft electrical tape on the hoop. it may or may not work but if it does, it's a hella lot cheaper than $250.

there are also the rubber bumpers on the sides... i beleive you can adjust those. i had to put some shims under mine but it worked. like Mapplex said, hella cheaper than 250 bills.

I had the same thing on my 00 OBS. To fault find, I put some foam in between the hatch and the frame, and it stopped. I tried adjusting the latch - no luck. I took the panel off and zipped tied/taped any wires/washer tubing that looked like it might smack against something if bumped - no joy. Basically, I sold the car and bought my RS before I got around to solving the problem. When I discussed the problem with the buddy I sold the car to, he said "What rattle?" Maybe I was just too fussy...

Good luck. I'm curious to see what'll fix it...

Thanks for the ideas! Cheap is the plan.

What made me also think of electrical tape is that I noticed that on the front doors the hoops where the door would latch are covered with what looks like shrink wrapped rubber/plastic = no metal on metal contact. Maybe this would be a good idea for the hatch as well.

k2blt, just to make sure I understand your suggestion for the rubber bumpers did you shim the hard rubber pieces on the hatch door (look like wedges) or under the larger rubber pieces on frame? What did you use for a shim? Any water leakage?

I'll admit that I'm also getting used to the noise. Even so, I had a full load of bags of leaves in the back today for a run to a recycling center. The pressure on the hatch made for a really quiet ride. Once I emptied the car the rattle was back.

Finally got the chance to play with the hatch today. Decided to start simple and went for the duct tape (couldn't find the electrical tape!). A little bit on the hoop, and took it for a drive. No more rattle. The latch is a bit more snug but I expect the main thing is no more metal on metal contact. Shims were the next step in case this didn't work

Thanks for the feedback!

the tape thing is a good temporary fix... but if you use the rear hatch door often the chances are you'll have to find a more permanant fix. the bumpers that i'm talking about are about half way up on the body frame. they have a screw in the middle i beleive so i just loosened and shimed them up slightly. i've had it like that for more than a year now and the rattle hasn't come back and haven't expereienced any leaking. good luck!

k2blt, point taken on the temporary fix.

I know the bumpers you're talking about. With the hatch closed and looking through the seam between the hatch and the body I can see about 1/16" - 1/8" space between the bumpers and the hard plastic wedges that attach to the hatch. I expect that shims would tighten the fit.

One question, do you remember what you used for shims?

Thanks!

anything can work if you do it right. i used some thin pieces of semi-hard foam and some double sided tape to prevent it from moving. be creative... at first i used some cloth to see if it would work, and it did, but the cloth holds moisture and the thought of that bothered me.

Dunno about the pre-02's, but on the 02+'s, there are rubber bump stop so the hatch doesn't bang metal on metal. You can screw them out: there is no real screw, the rubber is a coil that threads into the hole. Twist the coil, it will go in or out. Screw it out a bit, shut, repeat, until there is no more rattle. Do both, there is one on each side.

That fixed it for me...
