2019 Nitrous Blue RS - Mountune prepared - Stratified tunned
I also have a kind of "clunk" in certain contidions (low speed mostly) with the yellow bushings.i just want to add to this. Ever since posting this I’ve had a thought in the back of my head. So at the same time as the diff bushing install, I also did sway bars and the fûcking garbage whiteline end links. My
Car has more noise and clicks and squeaks etc but I think I spoke too soon.
with the powerflex street RDU bushings x3 there is no extra vibration or noise, but you do notice engagement of the diff. If you’ve owned rwd cars then it’s more akin to the ‘driveline shunt’ you get when you’re on/off the clutch at low speed. I realize now that the feeling is what made me go and double check the torque of the bushing bolts.
totally still fine and would probably be not noticeable at all in other cars (I have the motor/rmm/trans mounts too)
I was worrying for long time...checking the bolts, removing the bushings to listen, checking the oil for metal particles, filming the diff when driving....
Finally, sound seem to be normal and learned to live with it, and since hard raced a lot with it.
At the end, it just show to use that the bushings are greatly improving the response of the rear axle.
I also have fully upgrade the front axle and engine mounts bushings and here too, suspensions and gearbox additional noises...
