Wheel hop and drivetrain shock will bust axels quicker than simply the tq you are making.
My car makes 450tq and would breaks axels on radials. When on a bias ply tire and preloading the drivetrain before launching it has broke zero axels.

there is no "magic" to axles. if you keep them greased up and sealed you will be fine. You can rebuild your own axles... odds are if it isn't dry and clunking the tripod is still fine. GET NEW BOOTS, get GOOD grease, clean everything in a parts cleaner or with brake clean, grease the tripods but DO NOT pack them. Re-install the new boots, clamp them down good, and you are good to go... chase the threads on the outside while you are at it and hit the inner with some sanding agent and rustoleum black paint, done.
Most racecars take A LOT worse abuse than drift cars due to jumping curbs and grip, and the axles last a lot longer than people would think, however they are greased after every weekend. The grease will push itself out of ripped boots and will ruin the axle... take care of your stuff and it will take care of you. |

Are you sure they are GT-R axles? GT-R axles are 5 bolts and the hub spline is bigger. so those wouldnt fit S-Chassis Hubs

GTR axles are 6 bolt like a q45 or 300zx twin turbo, no large spline axles are 5 bolt. Yes I have the larger hubs installed in the car, the axles came out of a r32 gtr rear subframe i ordered.

Hey guys, wanted to chime in as I just recently did a Autozone-Axle swap on my S13. If you're familiar with our red car it's running 18x12 with 305/30/18 Nitto NT01 on the rear and then we swap down to a 18x10.5 with a 255/45/18 (or whatever is around this size and cheaper) Kenda/Nankang/Federal for the majority of our drift-day session. We're running a 350whp SR on a Z33 Transmission (Maverick Motorsport kit).
I blew the stock axles after finally changing to z33 after blowing a couple SR transmissions. Went to autozone for the convenience/price as time doesn't really permit junkyard-hunting. Everything looked good and nice, I also noticed the i different boots as noted above. Swapped them on and ran one event, the car rarely drives on the street, and they held up fine no problem or noises. Parked the car and decided to drive it down the street and after a few clutch kicks I started getting this LOUD knocking noise (sounds just like a horrible motor knock) from the pass. rear. It is throttle and speed based, only making noise under a load (not coasting, clutch in, etc). I have since driven the car on the street for a couple 'cruises' with some buddies and the knocking noise stays the same. We have adjusted all the rear suspension and eliminated that as the cause to pin-point the axles as the issue. Note that I haven't tried adding grease to the autozone axles, I do believe this could be done to eliminate the noise and last longer as a buddy did recommend adding grease before originally installing. Now, it's the most annoying sound to cruise with, horrible. Axles are working fine but I would assume at my next event after a few heavy clutch dumps they will go again just like the oem ones. SO I have purchased a set of oem used Z33 axles and the new Maverick Motorsport axle-conversion plates to give these a whirl. I know the guys at Get Nuts Lab have been running converted z33 axles for quite some time with much praise, so hopefully this is the right way to go for anyone upgrading power. I am yet to finish the install and most likely won't remember to update this response, but hopefully it works out well and if someone is curious please PM me so I remember to let you know. Thanks! Just wanted to share, good luck with your experiments/cars guys! -Scott |

I dont understand why anyone would try and abuse a stock axle or even worse a shitty china one over and over. Just upgrade to Q45 style ones, its not that much money and its much much stronger.

I just tried to install the maverick z33 axle adapters and used/good z33 axles last weekend, and was left with a bad taste in my mouth. I have pbm subframe risers, very low ride height with 0 camber, and the differential is raised up higher in the subframe about 1 inch. The driver side z33 axle was too long as after installing it and driving the car, the inner cv pushed through the inside and came apart leaving me stranded. Also, the passenger axle seems too short because after installing and setting the car down, the stub shaft pulled out of the differential about 1/2". And yes the "long" axle was installed on the passenger side, and short on the driver side. With Oem axles the driver side has never had a problem, but the passenger side has always been an Autozone unit, and the inner cv cup breaks apart when shifting from first to second gear driving hard. This is with a custom made 20mm axle spacer. |

Hmm, that's crazy dude. Sorry to hear you were stranded. I finished my install and noticed the driver side was a bit tighter, I had to adjust out my rlca to allow more but once I did that no problems. I also am running the PBM risers and oem rear spindles, oem rear diff with kaaz. I'm running about -2* camber in the rear though.

So you're okay with running a different track width on one side of the car than the other side? That just really doesn't seem like a good thing to do. I've got pbm risers, oem spindles, osgiken 2-way and 0 camber. If i adjusted the driver side rlca out wider, matching the width on the passenger side would make that axle too short :/

I don't understand why people overcomplicate the axle thing so much. Any axle, no matter what, even an R35 GTR axle will clunk and break if the boot gets torn. Its exactly like running a wheel bearing with no grease and sheering off the spindle...
If your boot rips, replace that shit immediately and be done. The boots are $15 and its easy as hell to do. There is no "spider" assembly crap like someone above mentioned... its just a tripod, dip the damn thing in grease, new boot, tighten the clamps, done. THE ONLY correct boots for our cars are the Beck & Arnley (O'reilly can get them), Megan, or OEM boots. NONE of the dorman ones work. Both the inner and outer boot is identical. An OEM or Autozone reman is essentially equal for all of our needs, end of story. They are simply rebuilt using oem parts with beck&arnley boots. No magic there. IF you don't have wheel hop or drive like an idiot these axles will take a beating and a half. I ran them with 585whp and 390ftlbs for a long time without any issues. This was a drag car with good bushings and didn't have wheel hop. Z32 TT/Q45 axle is cheap and easy. Way easier than most realize. If anyone needs Left side 300zx TT axles (the hard one to find) let me know as I have a ton of them oem and brand new in the nissan box. |
