Quietest differential bushings (not oem)
Hi all,
I currently have a set of differential bushings installed in my car and I’m getting a bit of noise. We suspect they are the cause. Haven’t removed yet but they’re red so I’m assuming they may be bmr pros. Either way, I am reading I can’t install oem bushings back in? Is that true even for a professional shop? If so, is the bmr street the closest to stock or is there a bushing that would be even quieter? Thanks! |

Thank you! I’ll check out the thread!
Sounds like Lingenfelter bushings may be quietest? Whiteline up there as well? Any more thoughts? Last edited by DMan918; 09-18-2020 at 09:54 PM. |

Does it clunk when you go into gear? Loose bolt... The differential will twist under load and the clunk is the bolt hitting the top of the slotted hole.

Thanks,
No I have a really bad howl from 40mph on up. This is while cruising (very light pedal engagement to keep speed). |

To mention, I know some people would want to come in and say install issue but I feel very confident in this shop and the work done so I really don’t think it’s related to gear setup. I’ll try to get a video today. Thanks for all your help! On edit: Here was something I did question though. Note the movement of the right axel. Is that acceptable or is it not fully seated with the lock ring? No leaks. https://youtu.be/Pb2iHglDQUM . Last edited by DMan918; 09-20-2020 at 08:03 AM. |

Mentioning the 4.11's to begin with would've been kinda important. You will always get whine with aftermarket stuff. As you mentioned before...gears plus aftermarket bushings....its gonna be noisy. My stock set whines with the BMR diff bushes.

Here’s a link trying to show the whine: https://youtu.be/T2fJZraTkOc We’re pretty certain it’s because we installed 4.11s and now the poly bushings are causing all kinds of noise. What may be a minor whine is just escalated into aloud one because of the bushings. The lingenfelter bushings are in order so hopefully that will resolve the issue.

Yep exactly. The bushings are doing what they are supposed to. I just prefer quiet at the expense of some diff movement.
