Nissan Dual Cab

used to work with a front end specialist. I did LHD conversions. From what I saw while working with him a lot of wheel alignment guts only ever measure caster, camber and toe. and a lot of 4Wd only have a toe adjustment only. See some one who has been recommended as a real specialist and not a bulls--t specialist and they will more than likely measure the full geometry of the vehicle, who knows it wouldn't be the first time a manufacturer has made a vehicle thats not straight I,ve seen it before and if it turns out that it's not straight or the rear diff is not mounted correctly the it,s Nissans problem. Hope this helps. In mean time measure frome wheel centre to wheel centre on each side and see if there is a difference, that will give you a rough idea.

most so called wheel alignment specialist do what we call a toe and go thats where they just adjust the toe and dont worry about the camber /caster adjustment.
navara have full camber/caster adjustment but there an absalute pain in the butt
to adjust.
7 wheel alignments hope it wasnt the same place.
take it to a place that will give you print out of then alignment.
the navara should have half to three quarter positive camber both sides.
and caster should read half a degrees more foward caster on the left hand side.
factory settings are usually even caster or more caster on the right because overseas there roads dont have nearly as much camber on them(leaning in to the gutter) so they usually dont pull to the left. where in ausrtalia most of our roads do have camber.
if you have swaped tyres side to side and front to back it sounds to me like alignment.
have a word with the alignment guy and ask about caster/camber and if there any good and with a little more caster on the left you shouldnt have any more trouble.
good luck and hope i havnt confused you more.

excellent tv prgrammme by the way,but i digress many of the vehicles sold in australia are designed for european roads which do not have any camber to the hence when these cars are driven on ozy roads they tend to pull to the left especialy under brakes larger tyres tend to make this problem more noticable the above comments can provide a solution to this problem but if you use this vehicle off road the bumps & bangs can ruin any adjustment that are made i seem to remember acompany going around a few years back offering a fix to this problem at a cost o around $300 but with no gaurentee that the problem would not return if the vehicle was used off road so iguess what iam saying is that you can spend big $$$ fixing this problem only to totally ruin the fix first time you go off road so just watch what the experts try & sell you as a fix & ifthey say it is a perminant fix get it in writing
