Hey all,

Just wondering if anyone can tell me whats the highest and lowest diff ratio that

can be purchased for a hilux or hiace diff? or any diff that would bolt into the housing.

I have a 4.1 , 4.5 and 4.8 ratio.

thanks

It really depends on the diff housing. I have an RN46 with G142 diffs (4.875 gears) and apparently nothing will fit it, in terms of changing gears with that centre. I was able to bolt a KUN26 centre into the rear housing (3.58 ratio) with minimal fuss, just the usual pulling of brakes, axles and new bearings while they're out. You can buy similar gears from Mark 4WD but you will need to change the diff centre regardless, any diff centre with gears 4.5 or higher should be OK to do this with.

      Transmission U660e

      Not every Estima is fitted with the 2GR-FE and U660e drivetrain. This is where you have to take care that information on the internet is applicable to your specific vehicle.

      Auto door locking on new 2024 C-HR?

      Hi I was very lucky to receive one of the first new models last month. My Koba is amazing- as have all of my previous Toyotas. However in answer to your question it does not automatically lock the doors when you engage Drive or when you reach a preset speed. I am very disappointed that with all of the electronic devices and safety features and the approximately 20% increase in price over the last model that Toyota Australia has left a very important safety feature out of the vehicle. We see cars being carjacked almost nightly on the news. My knowledge of technology in this sector is limited but surely it is only an update of the operating systems to fix this. The new model is a beautiful car- your wife should still buy one.

      is it possible to import US model Sienna to Australia?

      I rent a 2023 model in US just few days ago it’s beauty and real good on fuel much nicer to drive compare to Honda Odyssey which I own one 2022 model make me wonder why Toyota AUS won’t bring the Sienna hybrid to Australia instead we get bulky ugly looking Granvia with diesel engine 🤔🤔!!

      How to delete bluetooth device?

      I have a Yaris and had a similar issue. I just submitted a similar query to GPT. The response was to go into settings, view paired devices, select the device to remove, and confirm the removal. It helped me; I couldn't find the answer on the internet, but I found it there.

      Transmission U660e

      @campbeam much appreciated, very interesting, it’s got me buggered as on the Toyota Estima groups everyone is quoting 1.6 litres cold for a drain and drop, now, these run the exact same drivetrain as the Aurion 2GR-FE and U660E combo, so in theory all figures should line up, I’m hedging my bets on your maths and techniques though, you seem well versed…. thanks again

      Auto door locking on new 2024 C-HR?

      My wife is looking at purchasing a new 2024 C-HR Hybrid. Does anyone with one of these know whether the doors lock automatically when driving off? Her 2018 C-HR doesn't do this which is annoying as my 11 year old Kia Sportage does.
