Drivetrain Whine with Rear Diff Busings
I just installed some Torque Solutions Rear Diff Busings and now i am getting a loud whine from the drivetrain, assuming the rear diff. The fast i drive, the louder the whine gets. Has anyone else ran into this with rear diff busings? The bushings didn't fix the clunking noise at all during shifting so i was starting to think of putting stock busings back in to get rid of this whine. Does this happen with all diff bushings? Im not sure why this would cause driveline whine now. Any suggestions would be appriciated

What your hearing is drive train noise ,not a whine . Is does not fix the "clunking" bit it does however stop the diff from flexing up and down to help save the axles and drive shaft from breaking under hard lounches and clutch droping .

i guess ill have to put the stock bushings back in then, as i can't stand that whine which is exactly what it sounds like. The only reason i bought them in the first place was cause they advertised them as getting rid of the clunking while shifting. What out there does get rid of the clunking. Does the moustache bar elimination help eliminate the clunking?

well seeing the urethane bushings did absolutely nothing for the clunking noise, which the original reason i put them in, i guess ill just go back to stock bushings. Anyway want to trade you stock mounts for mounts with urethane bushings installed + cash?

Last summer I installed the ES rear diff bushings (mustache bar included). No clunk and a not-so-overwhelming whine from 75-85mph. Thats about it.
A few friends used the same ES bushings and all had the same results. Seems Energy Suspension found a sweet spot with bushing stiffness. You could try upgrading your driveshaft carrier bushings. I didn't notice a huge difference but might help *shrugs*

I had white line rear bushings fitted on my evo 8 MR (JDM Evo, I don't know if they have the same diff as the USDM spec), and it fixed the clunking without any noise from the drive train.
