Hey everyone got a really strange problem with my disco, it's a 300tdi manual, a few weeks ago whilst I was driving along something weird kept happening, the steering went really funny and felt like something was holding the front end back ( really hard to explain) I thought it was the brakes locking on or something rubbing on the wheel at first but the other day I decided to try the difflock out so drove it in hi difflock round the block and it drove exactly like it was when I was having the problems, so basically my transfer box is locking itself while I'm driving even tho the lever is out of lock and only locks for a couple of seconds or so, just want to ask has anyone else experienced this strange problem? And is it an easy fix or is a new transfer box job?
