Erm, we'll if not that then 15 mm spacers will help in the long run. Get hub centric aluminium spacers.

Thanks for the suggestion but I am not a big fan of aftermarket modifications in my vehicle . I like to keep it stock. I am pushing the ASC to find the root cause of this problem and fix it for me at the earliest.

I am on my way back to Bangalore from Chandigarh and just as I started the journey, a very weird issue has cropped up. Now I am not a newbie to using 4WD but for some reason 4H is getting automatically engaged.
Its not the message on the dashboard but I can also feel the same. As the journey progressed it became less frequent, so the only solution was to stop the car, put it in Neutral, engage 4H, no message on dashboard, wait for some time and then put 4H to 2H. Check for the message of 4H getting disengaged and then move on. Not only 4H but in a few instances 4L was also engaged.

One can only wish.
Look at the scorpio N. The wheel clearance is abysmal. Even on stock 255. Has all sorts of rubbing issues.

Can anyone share the bolt size of on front door Hinge of New Thar?

I got to change them as the ones fitted by Poona Motors(Pune) during installation of foot step are of really low quality and have rusted badly. They took off the old (OE) ones with chisel n hammer and fitted new Hex ones.

It is surprising to see a problem like this. The Thar has a mechanical shift and for that to Automatically come to 4H or for that matter 4L is highly improbable. If you engage 4L while driving, you will hear a definite grinding sound.

Could you elaborate how you can feel it ?

I am sharing the video and am surprised myself. This happened randomly whether I was in Cruise mode or driving manually (without the cruise).

Can you explain what happens when it gets slotted into 4L.

Similar to how it would go in 4H. Its not just on the dashboard but the car drive changes because it is using the 4WD on its own. And you s slotting the 4H and 4L works like a charm. Right now I am at Anant cars Bangalore, waiting to see what they say. My suspension is some sensor or mechanical part is fidgeting.

You mean to stay the car slots itself into 4L on highway speeds? And you suddenly start going slowly in higher RPM's?

Yes, that's what happened. 4L showed on dashboard and I could feel the pull. To my surprise, Mahindra guys weren't shocked and looked normal when I showed them the video. Will get Thar tomorrow and keep his thread posted on the findings.

Update - Got Thar serviced today, completed 30k kms. They checked the 4WD - Mechanically and using the Fuse. More details from here - https://fuse-box.info/mahindra/mahin...021-2023-fuses

They kept the vehicle for a day and found no issues or were not able to replicate it. I have had the vehicle for a day and so far 4WD is not getting auto-engaged. They have not replaced any part related to the 4WD mechanism in the vehicle. I have no clue, how or why it happened and if it is fixed, I would never know why or how.

From the video you posted, the tranfer case lever (the shorter gear stick) is in 2H and the indication alone for 4H is showing in MID. My guess would be wiring connection/ sensor issue, making the vehicle think that it's in 4H electronically, maybe engaging the front driveline (the Thar has electronic driveline disconnect for the front axle to disconnect the wheels from the front axle in 2H).

Please keep an eye out in case this happens again.

BTW, saw that you momentarily shifted to 4H and back to 2H using the tranfer case shifter to get rid of the false 4H alert in the MID - while the vehicle was moving at 40 KMPH or so. This can damage the tranfer case and driveline components, a better way to do the toggle will be to pullover the vehicle, park and do this toggle. I know it could be irritating to pullover from highway speeds, but engaging 4H using the 4WD lever at speeds is a no-no -

I will try your suggestion and know that the best practise is to have on neutral while engaging and disengaging 4H or 4L but its happening at a time when I am driving and with the traffic coming and going, it is not possible during these instances to either pull over/slow-down to put the vehicle in neutral.

As of now, just because of this issue, the driving experience of Thar has gone for Toss. The issue was seen again today even when the vehicle was in neutral. I don't think that the ASC did anything for rectify this issue. I have escalated this and will keep the thread posted.

This was when the vehicle was at a standstill.

IIRC, yours is a 2022 Thar so ideally wiring niggles should have been sorted. Nevertheless, please ask for the CCM aligned to your dealership and show these two videos. Talk to the co-tech of the dealership and ask for a fix.

This definitely seems to be a sensor issue in the tranfer case (or related).
