Rattling Sound Coming from Front - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

antonio88x · 08-14-2020, 12:18 PM

Hey guys, does anyone know what could be causing this noise? It happens whenever I go over something bumpy, such as reflectors on the road, uneven surfaces in parking lots, crossing over train tracks. Anything that would jolt the car. At first I thought it was the hood catch, but I’ve adjusted that and it didn’t make a difference. In the video I’m driving over road reflectors. Thanks in advance.

Could you tell us the modifications to the car

First things to check:

- Sway bar endlinks
- Strut top nut

Pretty much stick a wrench on all the nuts/bolts under the wheelwell and make sure they are tight.

I checked the nuts on the diagonal strut bar and the 3 nuts that protrude through the body on the top of the struts and those were tight. Is there one particular nut at the top of the strut?

Lug nuts all tight?

The one under this cap. You'll probably need a pass-through wrench or an impact though, or a way to keep the strut shaft from turning underneath.

Okay, I have an impact wrench. I’ll check it and see if it’s loose.

Last night I took of the cap on both side and tightened the nut with my impact wrench. It didn't make a difference to the rattling noise. Any other suggestions? Normally I'm good at diagnosing issues, but this one is escaping me.

Then my money is on the sway bar end links. The nuts could be loose or one of the ball joints themselves could be bad and knocking.

Steering column. Mine had to be replaced around 60k. Somewhere here there's a thread and it was actually a clamp or bearing or something like that, it might even have been the thread I started a few years ago. I'm a few beers in now so work up your search fu and make it happen.
