PurePontiacKid Posted November 14, 2011 Share Posted November 14, 2011 Hey, so as you may know, my car had a VLSD and CV axles. Well, one of the axles broke, so now I'm back to a regular welded R200 (same case, just different carrier) with the U-joint halfshafts. Now, my car has this super gnarly vibration/rumbling noise from the rear-end when I'm coasting out of gear (above 35mph). It doesn't make the noise when the car is in gear coasting, or accelerating, only coasting out of gear. I had a similar issue with my stock R180 diff and U-joint axles. Could it be the U-joints are bad? Everything under the car is tight, no play in anything. I also disassembled the axles and re-greased them. Could I have put them back together wrong and now they're out of balance? Quote Link to comment Share on other sites More sharing options...
GLENN280ZX Posted November 15, 2011 Share Posted November 15, 2011 I did the grease and clean on my '80 280zx with ujoints. I timed the ujoints to be in line..and had a bad vibration. Reclocked the joints to be 90deg. dif. and the vibration was gone..so I would say YES to maybe having done something on the half-shafts.

I was just about to say to check whether the u-joints were in line or not Quote Link to comment Share on other sites More sharing options...
palladin Posted December 4, 2011 Share Posted December 4, 2011 What do you mean "to be in line?" They only go on one way, don't they? Quote Link to comment Share on other sites More sharing options...
PurePontiacKid Posted December 14, 2011 Author Share Posted December 14, 2011 nope, they can go in at all sorts of different positions. I lined them all up and it sorted most of it out, then I pulled more camber (had like -4.5*, now I'm at about -3*) out of the rear and helped even more lol Quote Link to comment Share on other sites More sharing options...
