4 wheel drive mode

[Wayne1903]

Hi guys I’m new to the forum I have a question when I put my Navara in 4 wheel dive in full lock it feels like the front wheels lock up any ideas what this could be

Sounds like transmission wind-up when the four wheel drive diff locks up on full lock - would advise not to use 4WD on tarmac too often to avoid damaging the transmission
