In reply to mypyrex:
It's amazing how much difference it makes, smoother and better acceleration.
Some recommend a blanking plate for the IRD unit when you dispense with the proposhaft, but I've never encountered any problems. There are a couple of caveats though.........
Firstly, I've only run a Freelander without a prop for a short while. Otherwise you need to change your V5 and tell your insurance provider that you've modified your vehicle to 2WD.
Secondly, recon units are around 200 quid and easy to fit which is why the prop was only off for a short while.
If you do fit a recon unit, make sure that all your tyres have approx the same tread depth otherwise you'll start wearing out the new unit. Freelanders are pretty sensitive to this.
Hope this helps
