Some feedback on the billies:
They've had a good testing, as we did a 4 month stint on the road from Sept last year, covering over 20000k.
There's more on the suspension work I did in my dmax thread since posting on the billies last year
Long story short, the rears are great and made a huge difference to the setup, controlling any ass-kicking from the camper. The unladen ride is good also, and not too harsh
The fronts, well, they were really good, valving maybe a tadd on the hard side, but really good handling characteristics.
About 3/4 wat into trip, I noticed the front was not reacting well to rougher surfaces or broken bits of road, whether dirt or bitumen, it seemed to shudder a lot more. Inspection led me to believe the right front shock was shot - Got 20k out of it. I thought back to the roads & conditions I travelled, and there was nothing untoward going on there - on the tracks, I dropped tyre pressures, and slowed down below 80 to preserve the whole rig - some places I had to 'walk' corrugations seeing as I had a jayco in tow..
Anyway, left the shock in place, and pulled both fronts out when I got home. Sure enough, the RF was buggered, but only from the top 3-4 inches of travel from full extension. With the LF one, I'm flat out pushing it in so that one is Ok, the the RF I could push in fairly easily only for the 3-4 inches, then it took up and the more i did it, the easier it got..
The shock is definitely the correct part number for the vehicle. What i noticed is that the shock tops out before the suspension does, and this combined with the front being wound up 30mm (not much, just over an inch) I think the shock was working at the top end & 'topping out' on bad surfaces, causes the valving at full shock extension to fail. The Billie is the same length as the std shock, so logic would say they maybe the shock needs to be a bit longer. The thing is, with these IFS front ends, you can't just bang in a long travel shock in , as this then puts too much angle on the CV's....
So, there you go, the much accalimed bilstein has failed, and the tracks were not that bad - The Jayco did not rattle loose anywhere, so there's proof of that
I'll have a chat to Zordo about it, and get a pair of replacement fronts from him, based on his advice as I'm running the stds up front at present and they are rubbish
