Suspension Rattle

kyriian · 05-12-2021, 06:53 AM

See if anyone may know what it is, it is also accompanied with vibrations at highway speeds.
I had the front end up last week, and i didn't see or feel anything's loose.

Check your bolts on the sub-frame brace. My suspension was driving me crazy for weeks making strange noises and I found two loose bolts, fixed the problem.
