Guest Drewz Posted September 11, 2003 Share Posted September 11, 2003 I have found a set of 4.38's in a front 85 nissan 4x4 and was wondering if the gears from that R180 would fit in mine or just swap the whole thing in? YES, I DID THE SEARCH>>>>>func. Are they reversed pattern??? Looks to be the same from the veiws I have had of it. I can get it for cheap and need the gearing for the AUTOMAGIC trans. I am running. I am running, for those interested, a stock non turbo 240z with a L28 with factory automatic trans. No bottom end and too long a legs in the top end for the crappy roads here. I have a 3.54 in it now and need a good sized jump as well as I am running a taller than stock tire.....Any info men?????? Quote Link to comment Share on other sites More sharing options...
johnc Posted September 11, 2003 Share Posted September 11, 2003 You should be able to just bolt in the entire unit. They 4x4 front R180s spin the same direction as the rear R180s. Quote Link to comment Share on other sites More sharing options...
johnc Posted September 11, 2003 Share Posted September 11, 2003 I've bought and installed 3 of the 4x4 R180s into a 1970, 1971, and 1972 240Z and never had a problem with the diff stub axles mating up to the 240Z halfshafts. Maybe I was just lucky. Quote Link to comment Share on other sites More sharing options...
Guest Drewz Posted September 11, 2003 Share Posted September 11, 2003 AWESOME !!!!!!!!!!!!!!!!!! 100.00 bucks is a good price for a diff and gears that needs minimal fooloing with than ??? Looking good ...........THANKS!!!!!!!!!!! Quote Link to comment Share on other sites More sharing options...
JMortensen Posted September 13, 2003 Share Posted September 13, 2003 There is another way to retain the axles, I've never seen it done in a Z, but I've seen it in Ford TTB front axles when installing aftermarket LSD's that don't have circlip grooves. You pull apart the slip yoke and put a spring in there, so that it is always pushing the 2 halves of the axles apart. There is still some room for compression, but the stub axles won't work themselves out. Works for F150's that are rockcrawling, should work for Z's. The trick would be finding a spring that is the right diameter. Jon Quote Link to comment Share on other sites More sharing options...
johnc Posted September 13, 2003 Share Posted September 13, 2003 Well... all the housings I have are K code (including the truck ones) but I always install either a Quaife or Nissan Motorsports LSD so that probably solves my bolt in problem.
