It's basically fusible links, don't jump it get a new box. Good to see you found the issue. Have you upgraded your subframe bushings yet? Those make huge difference.

[@TheFuelChannel]

Thanks man, going to order a new box since they are only $60. Still on stock subframe bushings and thinking about getting aluminum ones.

[@in54ne82]

@@TheFuelChannel You will love the car even more. I have bimmerworld solid aluminum ones and they have no noticable nvh.

Hey Bro, im having this same exact issue/noise with this driveshaft. Do you have a link to the bushings and did you just hammer the metal up further?

[@revo.d]

Yooo how did you do the LSD conversion? Any custom fab?

[@MrKpodczaski]

Hey did you have to do any programming after for the diff?

[@TheFuelChannel]

You don’t have to, but it’s recommended to turn off e-diff.

Link for these bushings?
