Size of rear axle nut?

[VMAX NV]

Does anyone know the socket size of the rear axle nut? It's the one without the cotter pin if that makes a difference. Thanks.

On my 03 the axle nut is 27 mm. - not sure if earlier models use a different size.

yep, 27mm just checked

There should be a wrench that fits it in your under seat toolkit....

 

[VMAX NV]

Awesome, thanks guys!

+ 1 @ 27 mm ....... What lb. torque are you going to tighten it to ? ?

 

[VMAX NV]

I think the book says 150 NM which is 110. So probably that.

While the manual says to torque it to 110 many find that this is too tight causing the diff to run hot. I have heard some run it at 50 ft/lbs without any issues.

+ 1 , manual is wrong . 40 - 50 should be good to go .

Thanks ,Rollie & Redbone for clearing this issue up, I noticed on my first rear tire change 25 years ago while reinstalling the back wheel that this seemed way too tight and backed off on the tightening specs and saw no ill effects.

Thanks guys, I'll tighten it less.
Who do I call when my wheel falls off at 120mph?:biglaugh:

Quick clarification , if you live in or near the Seattle area , tighten per spec.

I found that my 1 1/16" prop wrench fit it well also.... it was super tight when I removed it, and my diff would be nearly too hot to touch after a while on the highway, especially if it was at extra-legal speeds.

I only did about 50 ft/lbs this time and the diff is much cooler now and no other ill effects.

+1 on the 1-1/16" wrench or socket. Works great on the diff nut ant the nut on top of the triple
