Since the day one the rear BC Racing coils have been an issue. Over smooth undulations, driveways, or dimpled roads it doesn't make a sound. But over "quick", high frequency bumps like expansion joints and sunken man holes, it clunks...LOUD. It's as if there's a gnome hiding in my wheel wells just wailing on my shock mounts with a sledgehammer.
Thanks to sac and silent for suggestions. I didn't ignore you guys just been busy with all kinds of stuff, the van included. So far, to troubleshoot this infuriating clunk, i've double checked ALL bolts in the rear to make sure they were torqued to spec, they are. I went ahead and even replaced a few bolts with new i had bought but didn't bother to put in. I've removed the shocks repeatedly, checking the collars and re-tightening the top mounts. At this point i'm driving around without the MS3 sway. I've also removed the SPC camber arm from the passenger side and have re-installed the OEM. Still clunks...
I'm at my wits end. I shot an email out to BC yesterday asking for a warranty replacement of both shock and mounts. I wish i had Googled "BC Racing rear clunk" BEFORE i ordered my set. The hits were SOOOO much that I may have gone in a different direction. Don't get me wrong, when it's not clunking, i love, love, love the setup. But it never fails. I'm driving along happily and CLUNK! DAMMIT@#$@#! I'm putting both the RSB and SPC back on this weekend and awaiting the response from BC. In the meantime, no highway trips for the wife and kids. I let her use it locally for errands but i give her the speed for road trips. This issue has been taxing, to say the least.
On another note, the front end rattle-click i thought was the coil was not. I pulled the coil and the mount was solid as a rock. I hit it with the impact (it moved a smidge) and slapped it back in. I'm going to start with the inner and outer tie rods and work my way up to the control arm. If that doesn't work i'm going to set the van on fire and dance around it naked...
