I've started using my Landy a bit more again. Taking it down quite a tough route today I got stuck twice - Once in a cross axle situation with a rear wheel off the ground and a second time when the front and rear diff grounded out in some deep ruts.

Currently the car has decent tyres and I dont want to go any larger because of rubbing problems (265/75/16), 2" lift and extended Pro Comp shocks.

Which mod is going to get me further and if it is the diff which one should I go for and what other parts will have to be changed. e.g. half shafts?

Thanks

I do agree that driver is the most significant part.

Although a little out of touch recently, I have spent qutie some time off road in Land Rovers (learnt to drive on the farm at 10 years old in a series IIa, got a 'project' to work on with my father when I was 15, trialled a bit in a series II, green laning in wales, northampton, leicestershire, wiltshire, peak district, plus 2 days desert driving in UAE).

My Landy hasn't seen much use for the last 8 years or so and 4x4s seem to have become a bit more extreme (dislocating springs etc). 10 years ago my car would be about as far as someone would go in terms of mods unless they were competing and I was wondering if the more recent items that have trickled down in to mainstream use were worthwhile additions, or if I was better off getting stuck when my skill runs out and use the winch or get a tow and saving my money.

First thing I'd do is swap your 265/75s for 235/85s. I've run both on 90s and the 235s are better - slightly taller but more importantly on a lighter vehicle like a 90 or SWB series based motor, they provide better ground pressure compared to the 265s.
My mistake. I'd actually got 235/85s on on the weekend (I also have 265/75s on a set of alloy wheels but don't use them much).
The shocks are nearing the end of their life (only about 20,000 miles, but 10 years old with rusty casings), so I will look into replacing them with somtething that gives me a decent amount of travel.
I'll do a controlled cross axle situation this weekend and see what is limiting the travel.

I've already got a milemarker hydraulic winch linked up to an uprated power steering pump. Pulls really well (as long as the engine is still running...)
Your point about lack of load on the wheel if the spring is fully unloaded makes sense.
I'll keep an eye out for a reasonably priced diff, but need to renew my rear shocks first.
