Not sure if this will help, but my Freelander 1 suffered a similar problem a couple of years ago. I found that it was down to having put cheap tyres on. I am now back with michelin tyres And the wobble has never returned.

I had to take my prop off to have the VCU sorted. I ran around for 3 weeks like that. Couldn't wait to get it back on! The old girl didn't feel right.
