In doing research on AJs 4x4 (after having work done and having it go wrong, really wrong) I finally found this old thread. Sadly, we have had an eerily similar experience with our ambulance, and a 4x4 conversion at AJs 4x4. Took it in Oct 2022, AJ took a vacation, when we picked it up, it didn't steer correctly, AJ kept it a week to fix that. It was evident that AJ had not done the work, had not even test driven it before we picked it up. Other things came up. After 500 miles driving on the 4x4 conversion, the engine blew up (most likely unrelated, just a catastrophic failure, but they did put a crimp in the fuel line when they moved things around, and fuel starvation could have been a factor. Unprovable, so we'll leave it there). Decided to put a new engine in it because we had done so much, and it was a really awesome rig (before the 4x4 conversion).
The mechanic doing the new engine discovers several issues with the weldings from AJs 4x4. He found that the fuel line was crimped and the structural connections were, in the words of two separate welders consulted, not just ugly but potentially dangerous. We get this repair covered by AJs via threat of lawsuit. Engine is in, mechanic is test driving it, and is so concerned about the handling and suspension, he takes it to a suspension person who says it is not right, but he won't touch it because of the work that has been done. He can't guarantee he can make it right. We found this out yesterday. (Took a LONG time to get the engine due to supply, so it's been 9 months since it has been driven)). We now have a very very expensive paperweight. Devastating.
I think the saddest part of this is we did our initial research, and found nothing but glowing reviews and video testimonies. But as I did deeper searches, I found three similar stories. I'm not sure if every company that does these conversions has some poor outcomes? Or is there a certain percentage that are going to be lemons?
We do not know what we'll do yet. An astronomical amount of money which will never be recovered, and we certainly don't want to throw even more money at it.
