Front Hub Bolts

[peejay76]

Anybody know if the hub bolts (showing different part numbers) are actually different? Or which one is correct?

 

Additionally, a better/cheaper place to source 'em? 

 

Thanks!

They are just M8 inhex bolts aren't they? 

Surely you can find a bolt supply with the same length in Hi tensile?

Seems the ones at the local hardware stores usually have a slightly larger shoulder on the head that has trouble clearing the hub cover cutouts. I'll try to be careful removing and installing the current ones, or see if there are any Xterras/Frontiers in the junkyard that have 'em.

I suspect that 40254-32G00 is correct for manual hubs (as it's the only PN listed from the lookup # for manual hubs), and 40266-50W00 is correct for auto hubs, and someone balls'd up the data entry and listed it for both of them.

 

But this suspicion was based partially on the listed year ranges and my assumption that the W/D22 did not come with auto hubs, which it turns out they did. The diagram for an '01 X shows auto and manual hub options, and lists 40254-32G00 for both.

 

I would then assume that the two bolts are the same... except that this post says they're not. 

 

 

 

I removed auto hubs from my '93 and my '95, and I don't tend to throw bolts away. If you break one, and strike out locally, let me know and I'll see if they're still hanging out in my bonus bolts drawer.

 

FWIW, I was able to get all the bolts out of mine without breaking them, though it did take some heat-and-beat on the '95.

im using stainless hex bolts that are way too long compared to original. my OG hardware was actually studs and nuts on the R50. They're the same through all 80-00 Nissan 4x4s from what I can see. my friends Xterra, brothers wd21 and my r50 all share same hub hardware

Thanks Slart for the kind offer! I'm going to CAREFULLY remove these (I think my main concern was the hexes getting ever more rounded), worst case if I hafta purchase 1 or 2 new ones, that won't be so bad. But I also need an "excuse" to see what's new at the junkyard!

 

Strato, did you run into any galling issues or anything with the stainless bolts? And I didn't know that about the studs and nuts, are you the original owner?

The manual locking hubs require longer bolts than the auto locking.

Moms og owner and was bone stock when I got it. and I've hit them with the impact and have had no issues. I meant to get them same length as the studs but they were like 1/4" longer but still worked. Hardware is hardware along as it fits properly, is as strong as or stronger, and can be removed as easier  than before.

 

Some other guy was worried about the rear trailing arm bolt and I just said get some metric high sheer bolts and you'll have no issues. just try and get the same size as before or what ever is common in your tool kit lol
