Hi guys, this is hard to explain but here goes..
If I keep my 2005 Auto sorento under 30mph the issue is not really an issue, however when you get above 30 you get a slipping or binding feeling. When you back of the throttle there is bearing whine sound. The faster you go the violent the slipping or binding becomes. It really has made a lovely smooth driving car into a nightmare. It has been in a competent garage, wheel bearings checked, front offside driveshaft checked. When on a ramp and all 4 wheels turning there is no noise, as soon as it is back on the floor noise and uncomfortable driving. Can anyone shed any light please

In the driver's side kick pane, there's a fuse board, remove fuse number 13 marker TCCS...first things first...this will disable the controller for the transfer case. report back.

Thank you, will do it tomorrow and let you know

Are the tyres more or less equally worn? (Better tyres should be on the rear)

Are the tyre pressures correct?

Thanks tyres a a nearly new matched pair

It will make a difference the TCCS controller is very sensitive, ideally the the 4 tyres should be same size,tread ,and make

And the other two tyres?

extremely important you have a matching set of tyres on these, make, ply, tread, etc, etc, if you have two part worn this will cause your issue, try putting the part worn ones on the front and try it, and as already pointed out try it with the tccs fuse out, if removing the fuse fixes it then get a mod kit for it, it disables the 4x4, it allows you to select 4x4 only if you want it,

Good tread, went through mot without any comments about tyres. Will check pressure on them all tomorrow. Rear tyres are the ones on it when I bought the car 2 years ago, replaced front ones in October as tracking was out and scrubbing tyres

Hi, I have removed the fuse, gone for a drive and that has stopped the issue. What should I do now? Many thanks Robert

What is the mod kit you refer to?

It's a mk1 which is normally rear wheel drive...the tyres with the most tread have to be on the back...you need to get yours moved from front to back....there is no central diff therefore the 4wd cannot be used on tarmac or surfaces where there is no slip...otherwise damage to the transfer case will occur.

There doesn't appear to be a lot of difference between front and rear tyre depth of tread. Would it be better to just get 4 new tyres? Is it ok to carry on driving with the fuse removed?

 

[rcwood08]

Yes,...there are plenty of posts on this forum about the TOD system...there are 2 speed sensors, 1 on the front and rear propshafts in the transfer case, they detect an imballance in the speed of the front and rear wheels..if it is detected that the rear wheels are turning quicker than the front, the magnetijc clutch is activated to engage 4wd...the system works very well and is sensitive unfortunately if the tyre tread depth on the front and rear tyres is even slightly different it will activate....you can either ensure that the rear wheels have more tread depth or fit a modification by inserting a switch to isolate the TCCS controller and only switch it on when you need 4wd.

Thank you for your time. This is my first 4x4 so I am experiencing new technologies

That's ok....anything you need to know about your sorento can be found on this forum.
