Ever since I bought my Subaru Impreza Sport it’s had a weird rattle at around 2,000 RPMs and every time I drove it I thought “As soon as I get home I’m going to find that rattle”. Well I finally did it (after a year and a half).

If something’s rattling it’s either a piece of trim, a heat shield, or some plastic cowling somewhere, right? Right. That’s why I was a little ticked that I waited a year and a half to look.

You don’t have to be a mechanic to fix stuff like this. Get a piece of cardboard or put on your junky shirt and jeans, lay on the ground a look under your car, feel for stuff that’s loose. Open the hood and poke around. It’s good to do that once in a while anyway to check fluids, so do that while you’re in there.

Basically everything on your car should feel “attached”. If there’s something that feels loose, that’s probably what’s rattling. Now find out how it’s attached and tighten it. Yeah, that’s it. I know you want to think it’s something rattling in your engine or transmission, but it’s probably not.

This was what fixed my Subaru rattling problem.

Here’s what’s under the front. Two plastic cowlings that are probably just there to keep rocks flying up into the engine or something. The one on the left jiggled more that the one on the right, bam, that’s gotta be it.

That’s it. Rattle gone. 1.5 years of daily frustration washed away with a few turns of a ratchet. I REALLY wish I had done that on day one.

What’s something you’ve put off for a long time that could’ve been fixed in five minutes?
