nazar Posted August 3, 2006 Share Posted August 3, 2006 Well a few months back i was on a freeway on ramp and all of a sudden lost connection to my tires, i had no drivetrain I coasted to a stop, and tried driving off again and all i heard were aweful grinding noises but the car wasnt really moving. Got it towed home If i baby it barely i can pull it in and out of the garage sometimes, sometimes not, but thats about it I jack the rear in the air and put it in gear and i can go through the gears and spin the wheels no problem, but when i gunned the throttle the tires spun up but also seemed like the wheels were moving in and out every time i stabbed the throttle, and it seems like whenever there is enough friction to the tire, it loses connection to the drivetrain Is this my wheel bearings? Stub axles? These are still stock 240z stubbies, i have a 71 240z with an lt1, t56 and q45 rear diff with mosler half shafts and billet adapter I have 280zx stubbies waitinng to go in Also, my 280stub axles didnt come with the big nut on the innside, can i just reuse my 240z nut? Since i cant find those anywhere for sale Also, is there supposed to be a metal cylindrical sleve over each 280z stub axle center? 1 has it 1 doesnt, can i reuse my stock ones if they are supposed to have them?? I just bought 280zx stubies from a junkyard Quote Link to comment Share on other sites More sharing options...
fastzcars Posted August 3, 2006 Share Posted August 3, 2006 I hate to tell you this Nazar, but I don't think the 280 "ZX" stubs are the same size as the 240/280z stubs. I seem to recall the distance between the inner and the outer bearings are different. The good news is that the large rear nut CAN be used. Maybe you can remove your stubs and compare the 2 and give us the info and pix about the 2 stub axles. Maybe someone can chime in to confirm this?

oinojo Posted August 3, 2006 Share Posted August 3, 2006 sounds like maybe your clutch flipped up the ghost:sad: Quote Link to comment Share on other sites More sharing options...
nazar Posted August 3, 2006 Author Share Posted August 3, 2006 i really hope its not the clutch, it sounds like its coming from the rear, plus it still turns the wheels when there isnt much friction on the tire, like it being in the air, plus the whole wheel pulling in and out when stepping on the gas on jackstands makes me think its something to do with the stub axles I know the 280z stub axles are stronger, thats why i got them a long time ago, just never put them in I'd be pissed if it was the clutch, it was a used clutchmaster dual friction but i put in a new disk, standard organic both sides Quote Link to comment Share on other sites More sharing options...
jbk240z Posted August 3, 2006 Share Posted August 3, 2006 a smoked clutch. Try putting the rear of the Z up on some car ramps. Then unbolt the driveshaft, and then apply torque to the pinion with a pipe wrench or something. If it "gives" then you have rear diff, problems. If not, the clutch is toast. Good luck and post what you find out. Oh, don't forget to properly chock the front wheels wo you don't run yourself over! Quote Link to comment Share on other sites More sharing options...
nazar Posted August 3, 2006 Author Share Posted August 3, 2006 do you guys think its still the clutch? If it blew up, wouldnt the car not even move? I think im gonna pull the stub axles to see if thats the problem, the wheels moving in and out under throttle makes me speculate the stubs...hopefully. I will find out this weekend I guess Quote Link to comment Share on other sites More sharing options...

I will find out this weekend I guess[/quote'] well if its almost completely worn down, the amount of friction material that is left would turn the wheels when its off the ground. That is because it take less amounts of torque to rotate the wheel when its not on the ground as to when it is. Catch my drift? Quote Link to comment Share on other sites More sharing options...
2126 Posted August 3, 2006 Share Posted August 3, 2006 Sounds like its time for some wrenching!!!! Sometimes the only way to know for sure is to open her up and do an inspection. Be safe and use some decent jackstands. Quote Link to comment Share on other sites More sharing options...
nazar Posted August 4, 2006 Author Share Posted August 4, 2006 no way is that disk worn down that far it probably had less then 100 miles on the new disk, if its bad its gotta be torn up or shattered completely, you simply cant wear off htat much material in 100 miles I will put the car on the lift and pull the Ebrake, and try to put it in gear, if the driveshaft still spins then its the clutch, if not, its gotta be a spline somewhere, axles or something, i hope its not the diff, its a freaking q45 for gods sake. And i really hope its not the trany Quote Link to comment Share on other sites More sharing options...
srgunz Posted August 4, 2006 Share Posted August 4, 2006 My guess is clutch is OK too. It sounds to me like an axel or halfshaft. Let us know. Quote Link to comment Share on other sites More sharing options...
nazar Posted August 4, 2006 Author Share Posted August 4, 2006 it better not be a halfshaft, i got those moser units that cost me a grip, so if its those, im going to be pissed and demand a replacement, but i dont think its them, they seem intact, i just really hope its the stubbies, since i got the 280z in the trunk lol Quote Link to comment Share on other sites More sharing options...

jbk240z Posted August 9, 2006 Share Posted August 9, 2006 Any updates on the problem? Just curious. Quote Link to comment Share on other sites More sharing options...
nazar Posted August 15, 2006 Author Share Posted August 15, 2006 driver side halfshaft punched right through the cv end into the stub axle...must have been that cage i installed backwards into the cv housing on the outside part so...1 new cv housing and cage and i am ready to go i hope Im gonna assemble it correctly this time, the cage on the inside on 1 side has the teeth stepped in, does that side point towards the inside of the halfshaft?? Along with this im goin to swap in the new 280z stubs, new bearings and seals, new control arm bushings, tokiko illuminas, coilovers, etc.... same for the fronts, gotta finaly get the suspension in order Quote Link to comment Share on other sites More sharing options...
jbk240z Posted August 16, 2006 Share Posted August 16, 2006 good luck on getting it back together. Quote Link to comment Share on other sites More sharing options...
nazar Posted August 16, 2006 Author Share Posted August 16, 2006 just gotta get my hands on a new cv housing and insides. The halfshaft looks to be ok, hell it better be, it cost a few bucks, lol I'm gonna put it back together this weekend and start doin all the suspension install at the same time along with the 280z stubs Whats this spindle pin everyone keeps talkin about? Like you need a puller? I just took the bolt off and pushed it out and slid the rod out and seperated the spindle from the control arm, is this what you guys are talkin about???

DavyZ Posted August 20, 2006 Share Posted August 20, 2006 I just took the bolt off and pushed it out and slid the rod out and seperated the spindle from the control arm, is this what you guys are talkin about??? You're the first one I have ever heard having been able to manually push it out that easily, but I do believe you. It's possible, especially if the previous owner had removed it before and then lubed it. Nice. Davy Quote Link to comment Share on other sites More sharing options...
