Trying to diagnose crackling sound when I turn. I've tightened every bolt I can think of, replaced half shaft and did a fill to spill transmission oil change. Sound usually occurs when accelerating or decelerating into/out of a turn and occasionally during straight line acceleration or a bump. Can't figure it out. Made a recording of the sound. (yeah the windshield is cracked, it's my rallycross car.)

Probably help if I mentioned where the sound is coming from. It's inline or just to the right of the steering column.

Check your motor mounts and brackets. I had a similar sound when I cracked my rear mount bracket. Of coarse I had a B20V that was driven pretty hard

Thanks! I'm pretty sure it's not associated with rotating items and I didn't focus on the condition of mounts just the bolts.

Follow up.... reinspected rear motor mount, had a crack in the mount at one of the bolts. Heading off to the junkyard, I'll let y'all know if it clears it up.

Short test drives and the rattle seems to have cleared up. I'll know better after this weekend's race. Thanks.
