We have had the CV spacers machined like you already to reduce driveshaft angle.
Off gear in boot? Sorry what do you mean? Burrs off the gear inside the boot?
Yes! Not necessarily uphill though. I had steering wheel wobble on the motorway, between 60 and 65 mph. Anything above or below these figures no wobble at all.
What did you find this was related to? Squatting off the rear? Why?
Appologies, it should read - ' A lot of travel/camping gear in the boot'
simply more weight in the back then normal.
Oil shocks loose they performance as you drive therefore Gas/oil are much better as the 'foaming' effect does not take place.
In my case rear end was sogging/ squating to much, front end was lifting so front wheels were 'dragged' inbord by the lower arm.
Is your lower arm OE size or already extended?
Your wobble looks like wheel releated so fine.
