Those tyres also look underinflated, that maybe aggravating the alignment issues.

Thanks heaps guys
I did a quick (rough) measure with a tape and found the passenger side to be around 30mm longer between the axles than the drivers side. Looks like I’ve got some work to do.

Weird tyre wear is typically a caster problem, will need specialist gear to diagnose properly.
Worn shackle pins or broken centre bolt can cause front to rear axle dimensions to differ so you’ll have to check all suspension components before you call on a mobile wheel alignment bloke.
Worn kingpins or loose wheel bearings can also cause strange wear but you would have checked those at annual machinery inspections.
Caster on leaf spring/axle setups is corrected by fitting tapered wedges between axle and spring.
Very common job.

If its an airbg Denning,Id have a good look at the front suspension ,as its trailing arms fabricated from light wall tube.........cracks in the chassis mounting of the trailing arms were pretty common.......generally a crack joining the two pivot points.............the moun ting of the fabrication to the Rockwell axle may also be loose.

FWIW
akso look @ where the spring sits on the saddle @ the axle
Look for movement ... as in a fine line and not sealed with dirt or rust etc
Check all chassis bolts th@ hold the suspension

Should open a pdf but who knows ?
Even though it isnt quite right it ahould give you some really good indications of what is or isnt wrong and hopefully take a lot of the guess work out

AshmenzO - His business involves correcting power steering faults, which give rise to
many tracking problems, including abnormal steer tyre wear.
Operators spend heaps on other corrective measures, often without result.
Worth viewing some of their U-Tubes if only for information. Paul.
