Series 3 Lazy diagnosis

I know that I should nip up to my lovely new workshop and jack the car up, but I've got a streaming cold and just don't feel like it.

The new toy behaved perfectly on the 90 mile trip home, but today it's revealed a problem on turning some tighter corners on a hard surface than I faced on Wednesday. Feels like a front wheel puncture and that the rim is climbing over the folded flat tyre. Much to my surprise, no puncture

First thought that 4wd was engaged, so back and forwards on the lever. Neutral, push the knob down, doesn't really stay down. Lever back and try the knob again and it sort of stays down, and sort of pops up when you go forwards again with the lever. Tried holding the knob up and selecting high then low. Try driving again and 'think' that it may be better. But I avoided tight corners and went to a garage and blew the tyres up to 50psi to help them slip if it is indeed locked. back into the same car prk and it's still doing it. Needs more power to drive it round parts of the bend, less in between.
Wouldn't there be some squealing and odd tyre noise if it were wind-up?

My other thought is that one of the hub UJs is packing up and binding on extreme lock. Never heard of that one before.

Actually I'm thinking back to driving along a farm track on Wednesday, the turning circle seemed huge. Which it might on a gravelly track in 4wd?

So, yes, jack it up and find out, but as I lay dying on the settee I thought I'd ask if it's happened to you and yours.

If it drags you round corners like its being rammed by a rhino while the steering wheel feels like its stiring a bath of starter motors then its working perfectly in four wheel drive.

Quite normal.

Getting it out of 4WD might be the problem.

Excellent @Bobsticle. I did check the mirror for rhinos.

Tunnel off and have a look. It's lived on a farm for 21 years, so I wonder if it's been left in 4wd for long enough to clag up the external linkages. Hope so. Easy fix. I've read of some having a broken pivot bolt, so mebbe that.

Still chuckling at how accurate your description is. Ta.

Clag around levers removed. 2wd now installed. Just need to remember to drop the tyre pressures before it rains...

My gut feeling (sitting in this lazy chair) would be differential - that's what should be working on a tight driving circle...

...failing that the front end is so worn out / badly adjusted the wheels are rubbing on the springs, or the UJ next to the swivel is being bent too far (or it is so worn there that it is jumping about)

Just needs more sawdust in the front axle. Not sure what colour Land Rover originally used though.

No, it's fine. It was just clag around the levers and pivots etc.. stopping the knob rod from coming fully up. Rhinos returned to the wild and an appreciably smaller turning circle. Oddly enough it's a little quieter....

Hopefully, 90 mainly motorway miles won't have put too much stress into anything. I mentioned raising the tyre pressures to 50psi help them slip if it was locked into 4wd, but they were already up at about 40psi when I started to add more, so that will have helped a bit too.
