I've been reading about the NVH about these bushings but I'm so tiree of breaking these bolts... ill tolerate a little noise vs wheel hop and breaking bolts. Wish me luck. Anyone else have these bushings? How have they held up?

I run the BK049 kit (poly version) and the NVH is quite loud. I can hear the entire driveline working and there is a hum/whine starting at 40mph and only gets louder from there at higher speeds.

I wouldn't recommend the BK049 for a daily driver much less the BK050.

If you are breaking bolts (and not bushings), then it seems like it may be more beneficial to look into a through bolt setup.

I have about 4 years on the solid aluminum diff bushings. It's been trouble free since.

I keeping going back and forth... should I put the through bolt setup or install the BK050 bushings. Mine broke when the car wheel hopped from 1st to 2nd. I hope the aluminum bushings will prevent the wheel hop from happening. I hope the rear isn't going to be so stiff to were it breaks a diff ear smh. I'm leaning more towards installing the aluminum bushings to prevent the wheel hop. If the car didn't wheel hop, im sure I wouldn't have broken a diff bolt

I don't have any videos handy. In 6th gear when I'm cruising along at around 60mph it sounds like a small vacuum cleaner, but I've gotten used to it.

I'm not sure if you also have headers, but cruising in 6th gear is when the car is most quiet so the whine from bushings becomes noticeable.

Skip the bushings and do the lethal through bolt setup.
