GS450H 2012 Differential
Hi,
I am facing a problem of almost dead rear differential on my 4gen GS450H RWD Fsport 2012.
Question is can I swap it for any differential? IS250/350, or GS450H previous gen 3?
To me they all look same and they should mate to XGRFSE driveshafts?
Except Final drive ratio they should fit shouldnt they? I cant remove the diff then dissassemble it refurbish gears/pinion ring and put together would take too much time I want to swap diff for a diff.
Thanks for any reply

Which exact model is this differential going into? IS or GS. Seem to have similar posts started the same time

The other one is about me replacing diff in my GS450H FSPORT 2012 RWD 4th GEN
The hybrid's diff is only used on the hybrid, and even worse, there is a break in part numbers based on production date - 41110-30B10 for 03/2012 to 06/2012 and 41110-30B11 for 07/2012 to 09/2015. So the exactly correct part is elusive to say the least. This said, it might very well be possible to fit a diff with the same 3.266 gear ratio and have it work, but that's not supported by a part number search. FWIW, the gearset is also unique to this model, something I've never seen before. Usually gearsets cover a wide range of differentials, so there's little doubt this is one pricey piece of kit.

I appreciate your hard work no it's UK model. There are diffs for 2012-2015 I will go wild west with this. And just grab one. I was about to go wild wild and grab one from previous gen gs450h but since you were pretty strict with to which it should mate I will go with just little bit of risk. Anyway thank you for the effort. As long as mounting points are same, shaft insert is same and final drive ratio is "same" I think it should be ok. I will report my findings in few weeks time.
