Thread: 91 Hi lux wof issue

A modification affects the vehicle structure – including an object or fitting affixed after manufacture that is welded to the chassis, sub-frame, cross-member or body of a monocoque structure (Note 7), and

a) is not excluded from the requirements for LVV specialist certification (Table 3-1-1), and

b) is missing proof of LVV specialist or accepted overseas certification, ie:

i. the vehicle is not fitted with a valid LVV vehicle certification plate, or

ii. the operator is not able to produce a valid modification declaration or authority card

iii. the vehicle has not been certified to an accepted overseas system as described in Technical bulletin 13 .

Body on a Toyota Hilux is not monocoque it's body on ladder chassis. The question then is, what are the steps welded too, body or chassis?

Includes, but not limited to, is my reading of that. Eg: Weld a towbar to something and see how you get on

Heating, drilling, welding or cutting the vehicle structure, modifying a roof bow, or modifying any part of the structure would be considered to weaken it

Yep correct, but if you welded the steps to the tub or deck on a ute WOF man won't bat an eyelid. I don't think the original post specifies what/where they are welded (if they did I missed it). If the WOF guy is concerned that they are welded to the underside of the body - he might run into an issue over interpretation of the 'structural modification' bit, but if they are welded to the chassis or even a factory production bracket then under the new rules it needs to be approved. There are probably a few ways to attack that, but as people have said probably the easiest is avoid it by cutting the steps off and welding a bracket to the step. Then boost some new holes through the chassis and bracket and out with the black paint and the 'mud and cowcrap on a brush' trick... After the chassis has been welded to arguably the problem can't be just removed but the rules don't really reflect reality.

I had a discussion recently with a WOF man over a bracket welded onto the lower radiator support bracket of a 4x4 - he was going down the track of requiring a cert on it as a structural mod. Lower radiator support bracket isn't a structural member on that vehicle (might be on some). He reluctantly conceded the point as two 25mm long brackets to mount an electric cooling fan shroud probably won't affect the crash performance one would think. My read on it is that the WOF men are running quite scared as it would seem that any decision they make that results in an identifiable result from a prang or the like can result in them carrying the lot now.
