325_driver 422 Report post Posted October 7, 2017 Hey all, bolted up the bumper mounts seems to be firm But i can tug on it and wiggle it back forward / up down- there's maybe 5mm play in it, seems loose Or is this normal play for rear bumpers (like they have shocks in them) Have no idea - hoping for some insight Thanks !

allan 295 Report post Posted October 7, 2017 Which part are you referring to front, rear bumper, bumper carrier or the plastic bumper cover see parts photos below http://bmwfans.info/parts-catalog/E46-Coupe/Europe/330Ci-M54/feb2003/browse/vehicle_trim/carrier_rear/ http://bmwfans.info/parts-catalog/E46-Coupe/Europe/330Ci-M54/feb2003/browse/vehicle_trim/trim_cover_rear/ Quote Share this post Link to post Share on other sites
325_driver 422 Report post Posted October 7, 2017 (edited) Rear bumper - seems to be like the carrier can wiggle around a bit but unsure if this is normal. Do you know whether the shock absorber in the rear bumper carrier has any play typically? or should it be super firm All bolts tight, all mounts in order - have checked- and rechecked Edited October 7, 2017 by 325_driver Quote Share this post Link to post Share on other sites

That diagram helped heaps - thanks Allan ... Jonathan Quote Share this post Link to post Share on other sites
allan 295 Report post Posted October 8, 2017 A big problem with large plastic bumpers they receive a knock and look ok but the clips behind get broken. and after some time the whole thing starts falling apart and the owner wonders what on earth is going on. Out of interest did you check how snug a fit the bumper was on the side retaining brackets as the bumper only slides onto them,not sure if they have a lock in place. A miss fitting or loose connect could course some increased play. The plastic bumper from memory is connected to the metal carrier bar by a number of plastic expandable rivets.

325_driver 422 Report post Posted October 8, 2017 (edited) yeah ... its as you say, It's definitely had some big bumps over it's history - and during the respray i really started opening the can of worms. Left hand side - sits really snug right hand side - sort of hangs off the mount - you can't notice from a distance - but on inspection it's quite loose, and i'm always concerned that i might connect with something and cause some big damage because it's not 100% So wondering whether i do some DIY to the mount to make it more snug - or find out if there are some broken rivets connecting to the carrier.

allan 295 Report post Posted October 8, 2017 Ok to do this unfortunately you may have to remove the rear bumper assemble. Or can get under neath and see if any of the connection points have been damaged or simply missed fitting to. Below a photo of a rear bumper bracket the red arrows show were the bumper slides onto these locators. It appears that the sedan and coupe use the same bracket 51128195321 /322 .But if a m sport they use a different one. it would take a lot of broken expandable rivets to allow any play between the carrier and the plastic bumper best of luck Quote Share this post Link to post Share on other sites
