How come nobody makes polyurethane bushings for g37 power steering rack?

 

Does anybody know where I can get a list of nissans and infinitis with awd 3.33 in the rear end possibly lsd too

 

You'll have to measure yours however I'm sure the whatever works for the Z will work on the G. Possible that the G35/350z cylindrical bushings might fit

Your best bet is to narrow your search to models that came AWD only and start documenting.

 

I found a few on eBay from sedans that have the right pinion flange

 

I heard that the internals from an Xterra front diff work to gear down the front
