So I was getting coilovers on my G37 installed yesterday, and the Rear Knuckle Shock Mount Bushing looks like it needs to be replaced soon. SPL makes a monoball replacement bushing but I'd rather run a poly bushing so I don't have to deal with the added NVH. Does anyone know if the Whiteline W62535 bushing from the G35/350Z would fit? SPL lists the same part number for both the 350Z/370Z so I'm assuming it would be the same? I was unable to find the OEM part number either.

 

Looking at an infiniti parts website shows the same bushing for both a g35 and a g37. Part#56219AL500
Only $10 online.

 

Yup just searched through several diagrams and found it. That's awesome then, I really didn't want to run a solid bushing back there. Poly should hold up fine with the true-type coils. Thanks alot!

 

Hope it works out!

 

Thanks Irish, I think I'm due to have those replaced too!
