Spline count on a 2011 GRX 4.8 Auto rear axle side shafts

Post by biggles » 15 Aug 2017 16:16

Need some help here.

On the above car I need to know the spline count. Mike Swann is reasonably sure that it is a H 233B with 31 splines.

I am very far from my troll at the moment and no way to check in the manual. Anyone know what the side-shaft spline count is in the 2011 4.8GRX Auto with OEM difflock are?

I think the manual got h266 and auto (or some? :think: ) got h233b rear diff..

I got a strong suspicion that the rear H233b diff is 33 spline and not 31... (busy looking for more info on this).

AFAIK the 4.8 Auto has 33spline rear & 31spline front H233b all round. The Manual has the rear H260.

It seems the only way to reliably tell is too look. It seems that it is common for suppliers to guess wrong when fitting lockers on the patrols...
Anyway Cape Transmissions have offered to have a look in the diff for free. :clap:

The 2011 Nissan patrol 4.8GRX auto has a H233B Axle with a 33 spline count. (At Least this particular vehicle).

Cape Transmissions tells me they have had more than one case of incorrect difflocks ordered for patrols. And big up to Cape Transmissions for investigating.

Good job we checked as everyone thought it was a 31!!!
