Fact is, the new Land Cruiser LC79 Pick-up has a front track 4” wider than the rear track (or axle). This was apparently done to accommodate the larger V8 Turbo Diesel engine, which absurdly may not even become available in Southern Africa.
Common sense dictates, and some seem to have experienced this already, that the narrower track in the back may present a problem, especially in sand. In our specific case we have added worries, because Wohni definitely has a higher centre of gravity than a non-converted Pick-up would have – plus – we will more often than not travel on the limit of gross weight, thus exaggerating any phenomenon and/or occurrence.
The obvious thing to do would be adding wheel spacers at the back. However, a 2” extension of leverage on each side is no minor alteration and may or may not cause havoc in difficult terrain. Doing a quick thumb suck I guesstimate the increase in forces applied to be approximately 3-4% each side, yes?
On a positive note, we are ‘only’ concerned about the rear and hence don’t have to deal with reinforcing ball joints, etc. Also, as far as roll stability goes we would definitely have an added bonus. Still, forces on the diff, bearings and the axle itself are reason enough to be concerned.
I feel somewhat between a rock and a hard place about this, but tend towards going for the added benefit of the spacers versus the minor risk of breakage, hoping that Murphy is not around when push comes to shove.
I would greatly appreciate any thoughts and/or input.
All the best
