Basic checks for a vcu-
1, it's there! Many people take them off if they are starting to get tight
2, it's not too tight in full lock. It will be a little tight but shouldn't hear the rear wheel scrubbing
3, get it on some wet grass or gravel and make sure you can't spin the front wheels.
Also check that the fish tank is dry, no clicking noises on full lock from the rear and it's got plenty of poke. When I was test driving different freelanders for my last purchase some were a lot faster than others. Blocked egr I should think
Also handy to know if the fuel pump has been done
