Does anyone know if the metal case inside the diff bushing on the rear subframe is interchangeable between na and tt?
I can get a diameter measurement for you from a NA subframe if someone can get one for a TT. Video of pressing mine out below : [yt]VVdZJPnF8C8[/yt]
I have a stripped TT frame I could measure when I finish work. Not sure what you mean by metal case though.
I'm not sure if I still have the bushing that I pressed out in that vid... but Its a tight fit. Maybe one of the mechanical engineering speople out there might know what tolerances constitutes a 'tight fit' and my resulting ID of the subframe bushing 'hole' can be modified accordingly. OR sevenhelpfulpenguins can measure the ID of the subframe and we can compare vlaues. :zlove:
My bushes are gone as well so can only give subframe diameter. I cut mine out, didn't take long for the diff bushes.
