Chevy Bilstein shock issue
I noticed on our 07 C190P that the front upper rubber shock mount bushings were squeezing out and distorting a couple of weeks ago. They are Bilstein shocks I put in last fall that have about 1000 miles on them. After a bunch of checking, phone calls, and sent pics of the original mounts (OEM), Bilstein has determined they sent the wrong upper mounts with the shocks, and they sent me the proper replacements. I wouldn't consider the situation dangerous, it wouldn't affect the handling, but eventually it could wear the mounting stud, and gouge out the mounting hole in the van. It would get noisy, however.
If you have had Bilsteins put on your 03-10 Chevy, front part #BE5-G611-H0, send me an e-mail and I will let you know how to identify if they are wrong and who to contact to get the right mounts if yours are wrong.
