it seems like you tried to torque your way out of it, initially I thought you had experienced a frontal or rear-ended accident that bent the shaft. Now from I can understand, you should check more of you LSD in the rear transfer case rather than the shaft. The shaft is stronger than the gears that make up the LSD in the rear axle.

 

it's a shame we can't use the 350Z's driveshaft.

some suggestions:
call around junkyards. there's gotta be a few G35's with intact driveshafts in the dump (hell, we hear about a totalled coupe every other day here). I believe there are website that try to keep a rough inventory of some junkyards too.

is it possible to modify a 350Z shaft to make it a bit longer? Any old machine shop should be able to fab up an adaptor or something.

finally, the parts that are most likely messed up are the connection pieces, rather than the shaft's themselves. if you can just replace/repair the connectors, it should be ok.


good luck in any case.

 

Maybe take it down for a balance check?

Sounds like it's more of a connection piece then the shaft
itself. For $40- $60 beans you could atleast have it spun
and checked.

If this was an insurance case? I would have it reopened. This
may run some doe if your talking rear/tranny as well. Just a thought

 

350z has a shorter shaft and its not a good idea to put all the power down on an adapter connected shaft. An after market shaft is running around 1000-1400 in CF.

 

me and my boy ( who has a 350z ) are gonna jack up both our cars and get under em and see if we can physically see any major differences.....is it safe to have someone drive the car while on four jackstands or should i be smacked for asking?

 

if done correctly, its not an issue.

I drive my other car on stands during winter season and run her
to 60-70mph + go through all 6 gears

 

That's not the greatest idea. Also you wont visibly notice the difference even if it was bent or out of sync.

hope this helps

 

im on my motorola Q right now....so i wont b able to check out what looks like a service manual picture until i get home...thanks alot for your help tho bro

 

the 350z has a carbon fiber drive shaft lol, look no farther. I read that in the nissan brochure at the dealership when shopping for a z and settles on a g35

 

If the driveshaft is a two piece (I've never actually noticed tbh) it cannot be replaced by a one piece. Two piece driveshafts are used to prevent whip in driveshafts longer than 68". A one piece driveshaft longer than that figure will be like a jump rope under your car. If its a two piece and less than 68", which wouldn't really make sense, as theres no added benefit of two piece vs one piece <68", it would be possible to swap to a 1 piece.

 

I thought that was <65"?

 

So the shaft without center bearing is 59.88. so unless the bearing is 8" thick there is no need for it?

 

I just did some research, the overall diameter is also a determining factor, consider our drive shaft is 3 and 1/4 inch thick, it's maximum length lies between 60" to 65" but this is evaluated on a steel/aluminum application, does this mean a CF shaft with 4 times the torsion strength could sustain the full length without problem?

 

wow cf driveshafts!?

damn, about 1200, is it worth it in all of your opinions?
