2023 knocking suspension from new. Ordered front struts, strut mounts, strut bearings, related replacement bolts/nuts, front stabilizer links and nuts. This is step one to avoid dealership debacle trying to troubleshoot knocking sound. This way I can proceed installing these new items with new H&R springs. If the thing still knocks after the spring installation I will use the chassis ears to track down any remaining knocking. I figure if the knock remains after replacing all these known trouble making items then the original struts, etc. (with 2200 miles) will still be good to reinstall down the road after racking up 30 to 40k miles on these new parts.
FYI these struts appear to be on a nationwide backorder. I called one dealer and they had to make one call and they secured me the hard to get strut. Sounds like some of the parts are being hoarded during backorders for some reason.
