Or can i just literally swap out the diff with not to much hassle? Dont diffs have to be set up?

I am happy to swap over a complete axle its not the hardest job to do.
As for which final drive i need i am not to sure at the moment as ive not looked but apparently its a 5 speed box if that helps.
Am i limited to one diff ratio or will a few different ratios be compatible and does that change things price wise a lot?

For the RWD's there are 9 ratios avalable...obviously the more power you have the lower the ratio you can get away with.
5 or 6 speed gearbox makes no difference to the rear axle.
Best to find out what you have first I guess.

I have 2 6sp 140s, a MWB with 4.27 that will happily take off in 2nd - 1st is next to redundant, and a Jumbo with 3.73, 2nd requires a bit of gentle clutch slip, 1st still a bit short. Previous van was a Mk6 5sp Jumbo with 4.63, with a full load it wanted a bit of care with the clutch engagement, the 4.27 Mk7 axle swap meant a full load wanted deft slipping on the flat, let alone hill starts.

Thats gone a tad over my head though…
What does this mean for my van..
Am i going to have a problem finding an adequate axle for my needs ?
The van will never carry huge loads just a small simple camper conversion front end of rear and then maybe the odd motorbike or two squeezed in the rear of the van at a push..
When it comes to performance ideally i just want something that will be more economical and easy pulling power and speed im not fussed about.
I do like the idea of a 6 speed box but that is expensive along with an axle and bits to match sadly

What Jim said...
If you can get a 4.27...it makes a good "all-rounder". Not too bad for pulling/towing and not silly rpms at motorway speeds.

Day van is going to be lighter than bed&toilet type, but still surprisingly heavy, pop round to your local weighbridge before you start, a welfare kit out is going to be somewhere close.
My Jumbo is just a basic insulated and ply lining job, as depending on how many bikes are in there, there's usually room for a double air mattress etc. Dirtbikes are in the 100-110Kg mark, so by the time there's 6 in there, plus riding kit and luggage for a weeks French/Spainish/Romanian trailriding and 3 up in the cab, it's not too bad. 4 fat 4 stroke road bikes, and it's getting near the limit.
I'll have a 4.27 Mk7 single wheel axle spare in a few weeks, just need to get round to putting the Jumbos 3.73 under the MWB as that drives around empty most of the time, and it's like driving a micro hot hatch
