i have the megan boots on my s14. they are good quality silicone boots and include what seems to be good axle grease, however, the clamps included with them to hold them to the axle seemed kinda weak. i work at a dealer and just used a set of factory BMW axle boot clamps for a better hold.

i have only driven a few thousand miles on them but my car is slammed and i do lots of burnouts/brakestands/drifting/autox with the car and they have held up fine. at least as good as OEM if not better.

Any update with Villains stubs? Buzzing around this thread, read through it all. Might be considering z33/34 I'll research on length. My setup (z34 cdX trans w/ S15 R 48:13 HLSD)

I just picked up a 3.69 q45 5bolt diff for my s13 2j w/370z trans. I was hoping to run the 93 j30 5bolt axles but I cant find them anywhere. No part stores even list them, except Napa who says they are back ordered and not sure if they can even get them. No salvage yards in my area have them either sooooo can I swap to the earlier q45 2x6 bolt output shafts and run 2x6bolt j30 axles or even just my stock 240 axles for now? Or are the j30 2x6 bolt axles not worth it? Ive been reading through all these damn threads and im still confused. Sorry if im just dumb

What you can do is run 6x1 output shafts (30 spline) into your q45 diff and get 350z axles. I do have 6x1 shafts available for sale.

Do the 350z axles fit into the hubs? or would I also need z32tt/q45 hubs?

[KiLLeR2001]

350z use the same spline count as stock 240sx/J30 axles.

[2muchboost]

Ok so after reading all of the threads here I think it is all finally making sense. So if you wanted to use the early Q45 3.54 diff you could use stock S14 hubs with 350z axles that will increase the wheel base a minimal amount?

Cant believe its basically impossible or very expensive to attain a Z32 TT Drivers Side Axle these days. I remember paying $90 shipped for one from Cali to NY and thinking that was expensive haha. The good ol'days.

[R@tch]

I recently did a z32 gearbox swap in my sr20 equiped s13 using a mazworx adapter plate. I completely overhauled the rear suspension and drivetrain as well using a r32 gt-r diff housing with cusco adjustable 1.5/2 way lsd and r32 gt-r axles and hubs.

Doing measurements I found that a stock z32 (2+2) driveshaft has exactly the correct length. Because the driveshaft support bearing position is completely different opted for an off the shelf aftermarket 1 piece z32 driveshaft, fits perfect.

diff/driveshaft connection on the z32 and r32 gt-r is exactly the same and a lot beefier than the s13's, see below for comparison:


r32 Gt-r diff, axles and hubs


s13 rear diff housing fitted


Ready to go into the car

[TheRealSy90]

Wtf upper control arm/traction rod thing do you have going on there?
Unfortunately 32gtr stuff isn't common in the states.

They eliminate the bushings in the knuckle and indeed combine upper control arm and traction rod

I don't ever remember OEM axles being that cheap, sounds unlikely. Unless you are talking about remanufactured. I still have a BNIB OEM Z32TT driver side axle I will probably try to display around the house somewhere as art, haha.

[kkaleher]

Will 97-01 q45 5bolt axles work the same as getting j30 5 bolt axles? They have the same spline count for the hub and look pretty similar.

S13 left - 23" compressed, 25" relaxed
S14 left - 23" compressed, 25" relaxed
J30 left - 23-3/8" compressed, 24-1/2" relaxed (early J30)
350Z left - 23-7/8" compressed, 24-3/4" relaxed
Z32NA left - 24-3/8" compressed, 25-1/2" relaxed
Q45 left - 25-1/8" compressed, 26" relaxed (early Q45)

S13 right - 25" compressed, 26-1/2" relaxed
S14 right - 25" compressed, 26-1/2" relaxed
J30 right - 25-1/4" compressed, 26-1/8" relaxed
350Z right - 25-1/2" compressed, 26-3/8" relaxed
Z32NA right - 26" compressed, 26-7/8" relaxed
Q45 right - 27" compressed, 27-7/8" relaxed

After looking at different parts websites I found the later 97-01 q45 (that has the 5bolt 3.69 diff) has shorter axles than the earlier (6bolt) diff. And they are apparently 29 spline, with rzeppa joints.

97 Q45 right- 24-3/4" compressed
97 Q45 left- 23-7/8" compressed

These seem close enough to work if you are running a later Q45 diff

[kkaleher]

Picked up some 97-01 q45 axles, I'm going to try to install them tomorrow with the 97-01 q45 diff I got.

[JimmBooost]

Sooooo... where are you guys sourcing your s14 OE axles from?? I'm building another subframe, looking for OE axles for now.

Thanks

[kkaleher]

Well NM on the 97-01 q45 axles fitting with a 97-01 q45 diff. The pass side axle is too long

[epik1]

Guys who are using the Villains stubs, are you using OEM axles? or OE aftermarket axles ok?

[LANcer06]

Anyone try a Q45 diff with R33 GTR axles and hubs on a S14?

[2muchboost]

Adding another inquiry here, anyone try the DSS Q45 Driver Side Axle mod services? If this is a viable option it would be a sigh of relief over trying to find a Z32TT Drive Side Axle.

http://www.driveshaftshop.com/import...r-upgrade-2193

@Killer....I used to find Z32TT Axles for under $150 shipped all day but I am talking about years ago. Been in the game for a long time. When Underground Racing put out that article with instructions on how to perform the 3.54 swap they were still available at a reasonable price. But I understand supply and demand.

4.3 plated+welded with villains stub shafts and z33 axles. feels AMAZING. nice not worrying about the rear end. fit perfeeectt

So what do these stub shafts and z33 axles differ from factory components in terms of performance?

[jaysgottaredtop]

S13/S14 axles have tripod CV joints. Prone to break at higher power levels, and don't last as long at extreme angles seen when lowering the car.

Z33 axles have Rzeppa (inventor's last name, pronounced CHEP-uh) CV joints. Can hold power reliably and are more capable of handling extreme angles compared to tripods.

S13/S14 and Z33 have different bolt patterns, so the stub shaft has a Z33 pattern flange welded on.

No additional performance, power wise. Just more reliable.

[da_crew10]

Thank you so much^, this plus a one piece drive shaft and a 2 way differential will be my next big investment.

So the z33 axles have the same spline count?

For the axle to the wheel hub yes. You only to to change/modify the output shaft from the diff for this to work.

[spooled240]

Bumping this up. Does anyone have any recommendations for QUALITY 240sx axles? The cheap reman's at the local parts stores are garbage and most used OEM axles are very worn by now. I'm not super low or putting down high horsepower.

[KiLLeR2001]

Best bet is some OEM Infiniti J30 3x2 axles. Those cars don't see the abuse your typical 240sx would, so usually the axles are still in good shape.

-OR-

Convert to a 6x1 diff setup and run OEM Z33 350Z axles.

[spooled240]

I dunno man, the J30 axles are still 20+ years old lol I'm kinda done with original Nissan axles. I can never seem to find a good pair without any play.

Has anyone had any experience with reman'd rzeppa axles? I would imagine those holding up to more power and funky operating angles a lot better than the reman'd tripods. Thinking about running an S15 HLSD with R34 GTT output shafts(5-bolt HLSD) and reman'd 5-bolt J30 axles(rzeppa).

Thats what I run. Problem is finding the output shafts and the axles, not nearly as easy as it once was. Plus, NISSAN has discontinued some of the axle boots. You can still get aftermarket, but for us OEM sticklers - that really sucks, its a big kick in the nuts from NISSAN.

I was a afraid of hearing that. Looks like converting to 6x1 to use z33 axles really is the best scenario if you want the availability of bulletproof oem axles..
