johnc Posted December 6, 2002 Share Posted December 6, 2002 The spacer goes with the hub. If you get a strut/hub assembly without a spacer then you have to get examples of each (they are stamped "A", "B", or "C") and try each one. The most common spacer is the "B" one, in fact, I've never seen an "A" or "C" after disassembling a number of stub axles. You can also shave down the spacer if its too tight at 200 ft. lbs. Shave a couple thousandths off and retorque. Keep doing this until the stub axle turn easily (but doesn't spin.) Not sure if everything is OK at 175 ft. lbs. but if the dealer puts all that in writing, its their ass if it fails prematurely. Quote Link to comment Share on other sites More sharing options...
John Greenslade Posted December 6, 2002 Author Share Posted December 6, 2002 I assumed the axle would not spin freely if the sleeve was too short, not to long. Doubt the dealer will put anything in writing. Quote Link to comment Share on other sites More sharing options...
johnc Posted December 6, 2002 Share Posted December 6, 2002 Well... now I'm confused. Maybe your assumption is correct. I'll have to look at some pictures and think about this. Quote Link to comment Share on other sites More sharing options...

The most common spacer is the "B" one, in fact, I've never seen an "A" or "C" after disassembling a number of stub axles. As John says, they're matched sets. And if it's not righ it'll be your ass before the dealers. Any binding in rotating parts in that area can easily lead to a potentially dramatic failure. Even the extremly stout Viper halfshafts fail...when?..when they get bound up on either end and aren't free to move a slight amount. Do you have the distance spacers from the 'new' struts? I think all of my sets are 'B's except for one and I don't recall if it was a A or C. The odd one out did come from a 280ZX FWIW. Quote Link to comment Share on other sites More sharing options...
John Greenslade Posted December 7, 2002 Author Share Posted December 7, 2002 Am rebuilding 70 240z. Have substantially refurbished rear suspension. I had new bearings installed in the stub axle and strut tower by Nissan dealer, but they did not have new axle nuts so returned without final assembly. When I got new nuts and torqued to the recommended +200 foot pounds the passenger side axle rotated "freely" but the drivers side was frozen. i assumed since I had changed strut towers to a later model in better condition that the sleeve from my existing stub axle was the wrong length. I took back to Nissan to disassemble and measure strut dimension so I could order appropriate sleeve (the only place that seems to have these is Victoria British). Anyway the Dealer reassembled at 175 foot pounds and say it is OK (at the recommended +200 it freezes). My question is will the lower torque make any difference. I'd rather deal with this now then have a problem 6 months from now when I have hopefully finished the rebuilt. Quote Link to comment Share on other sites More sharing options...
