I just finished swaping out the open carrier for a NISMO LSD unit in my R200. I have been running 280ZXT axles with the open carrier with no problems. The installation of the LSD unit went perfect. Everything went back into the car with out a problem. The axles snaped into the diff. no problem. On the test drive I could hear a slight rubbing/grinding. It turns out that the axle on the passenger side of the car is making contact with the diff housing right next to the axle seal. The axle is going to far into the diff. The axle snaps into the splines with the snap ring and everything looks good. The axles are in right as far as the overall length, side to side. Any help would be great.
