I'm getting a lot of vibration in the steering wheel between about 50-70mph. Its when i'm already at that speed and am maintaining the speed on a motorway for example. Not when accelerating or decelerating specifically. I initially thought what you are thinking... balancing issue or tyres... spent £500 on 4 new tyres & balancing, vibration is still there. Am i missing something obvious?? Is my tracking likely to be the culprit or... something worse?... dun dun dun! Any help appreciated, this is my first 4x4 so i'm new to this!!

Look at propshaft universal joints and splines or driveshafts my PC is slightly to the right of Genghis

I had something similar which turned out to be a worn front CV joint. Jack up wheels and see if you can detect play at either end of each half shaft. 3 x FL1 2 manual + 1 auto

Good ideas, thanks folks. I have all weekend to try and find the problem so please keep firing suggestions that i can look at!!

I had exactly this after a new set of tyres. Took them off and rebalance them a total of 5 times but no change. Took it to a garage with a Hunter Road Force balancer and that cured it. These were Yokohama Bluearth all weather tyres. It was remarkable the difference. Expect to pay £10 per tyre but cheaper than a lot of hunting about ... good luck.

Weekend checks didn't help much, i couldn't see any play in the joints as suggested, tried a few things to no prevail. Interestingly, another problem has arisen, loud rattling noise from underneath the car, sounds like the exhaust/heat shield maybe?. I have run it into a garage and they are about get the car in the air and inspect. Could a heat shield underneath have been the problem?? Doubt it, but wouldn't it be lovely to kill 2 birds with one stone! Will update in about an hour as in the garage now!
