waynekarnes Posted November 30, 2003 Share Posted November 30, 2003 72 240z, V8. 4 speed, scarab modified hurst shifter, swap doen around 1976 ( scarab kit ??? ). sat for 10 yrs. i bought it, to bring back to life. a few test rides during the summer, normal z clunks and rattles. has 200r and 280 axles ( stubs, half shafts, what ever they are called ). prev owner replaced most everything with new parts ( ten years ago ), most parts still have nissan parts stickers on em. recently, took it around the block, have a loud ringing noise, as if one were running a wet finger around the rim of a fine crystal goblet. or a skill saw, cutting wood, coming from the right rear. wasn't there when temps were warm, now that it's colder, it's there. no idea if it goes away. on going mechanical issues, prevent any long adventures, and speeds over 35 mph. this z thinks it's a fiat, i fix one thing, something else breaks. almost makes me want to toss the towel in. any way, that ringing, comes from the right rear ... man i hope it's not a bearing ... thoughts ???? experience the same thing ? thanks, wayne Quote Link to comment Share on other sites More sharing options...
zero Posted November 30, 2003 Share Posted November 30, 2003 I have a 72 with a modded l24 and i get a ring, though mine seems to be only above 3000rpms in 5th, and is not very all that intrusive. I have yet to diagnose my problem, but I just thought I would let ya know I've got it too. Quote Link to comment Share on other sites More sharing options...
Guest Nic-Rebel450CA Posted November 30, 2003 Share Posted November 30, 2003 Have you tried checking/changing the differential oil? Quote Link to comment Share on other sites More sharing options...
waynekarnes Posted November 30, 2003 Author Share Posted November 30, 2003 the ringing in mine, is as soon as i get up around 12 mph. really loud. i have aluminum drums and replaced the shoes ( new wheel cylinders, new shoes, both rears and, 84 toyota calipers on the front ) with the semi metallic green shoes from nismo. i was thinking, if was the shoes , would be on both sides. no idea if noise was there before, as cylinders were bad, engine wasn't running. i haven't changed the fluids, though i'm sure it is a good idea . have only driven it maybe 10 miles since i bought it. in my z, the ringing is only on the right rear. no question about it transferring from the differential to the wheel, way too loud for that. thanks, wayne no idea why my messages are posting twice ...
