Jimny steering issue (not death wobble etc)

Hi all, my names Tom... I’m new to this forum so apologies if my etiquette is lacking at all.
So I’ve owned my Jimny (52plate) for a while now, I’ve been using it as my daily driver and a weekend play toy for the local lanes here in wales!
Touch wood it’s been a great little truck and has so far has eaten everything that’s been thrown at it with no issues or breakages etc...
Unfortunately the other night during a green lane run it seems to have developed an issue with the steering, at first due to being in a pretty much straight lane I didn’t notice anything other than the odd mysterious clunk while adjusting steering and the occasional rattle sound, it wasn’t until I got back onto tarmac that I realised the turning pitch is restricted severely on one side... I can turn the wheel (from center) almost 2 full turns to the left until full lock.... but when I turn to the right I’m getting literally 2/3 of a turn if that and the steering locks as if it’s reached it’s maximum point and I mean it’s solid! Had a look underneath and can’t see any obvious obstructions... the panhard rods appear to be solid and in tact, I can’t see anything obvious that’s broken/cracked/dislodged etc so I’m a little bit stumped! Unfortunately as much as I have common sense and the willingness to get involved, my mechanical knowledge is very basic/minimal so I thought perhaps one of you fine fellows could make a suggestion or even an educated guess? Many thanks in advance.

I will second Lambert on broken CV. You wont see it as its inside the swivel, but that would cause the issue, especially if everything else looks ok.

Thanks very much for the quick reply, I will most definitely get onto Martin and change the kingpin bearings and oil seals at the same time as the cv joint.. I’ve read many an article stating that the kingpin bearings are almost always perished so I was planning on doing them at some point anyway... I guess this was my kick up the backside to get them done hehe.
Again, many thanks for your help!
