I got Packard to engineer a GVM upgrade on my Landcruiser, and this involved building a four inch wider rear diff housing, which was fine, but the Dana axles they installed were standard length. This meant that there was only 8mm of spline engaged into the Harrop centre. This was a week before an 8 week trip to the NT. To the credit of both Dana and Harrop, it made it to an isolated spot between Kununurra and Katherine (about 3,500 kays) before it let go.
Anybody would be able to feel the splines engage when assembling a diff. Surely, when it only went in 8 mills they would have picked up that something wasn't right. The wife will never let me forget that "holiday"!
When I contacted Packard they didn't give two craps. I never received an apology from any of them, and they put the blame on the axle supplier. What a cop out.
Nope. Buy a licenced car from interstate, and you have to get it over the pits when you get it home. Engineered in a different state? Too bad. Get it done again.
You can in NSW if the interstate Engineer is accredited for NSW. I looked at buying a stretched and dual cab converted 100 Series before I bought my Ram. It was fully Engineered in Victoria including the Supercharger on the 100 Series V8. But the Engineer wasn't a NSW signatory thus it would ave been a nightmare to register here in NSW.
