GRRRR!!! suspension mounts all wrong
andrews_45 - 16/8/06 at 07:06 PM

I just come to mount my wishbones and the mounting points are in the wrong place. I bought the chassis from a manufacturer so have not checked this before now.

The top ones are not that bad and can fit in (allbe it at a squeeze) but the bottom ones wont fit at all






I will have to cut the bottom ones off and re-weld I know... But will I be ok with the top ones like that?

PS sorry if the pics a bit confusing my chassis is inverted at the min :-)

Are you sure it's not the wishbones pulled in when they were welded? Manufacturers usually put the brackets on using a jig.
Looks like a Luego (in a former life) chassis, is it?
Wishbones may spring a bit if you put your foot on one side and pull the other.

Or have I misinterpreted the pictures?

You'll only have to do one each side won't you ? The top one looks alright, can you put a threaded bar through both brackets to check the alignment. It has a support web welded to help with it hanging off the tube.

I checked the dimensions and the wishbones are to the correct sizes, the bones are from Luego but a different chassis manufacturer, I'll just have to remove the brackets from one side.

Before you do anything I would check the chassis carefully across the diagonals from front to rear suspension pick up points also check length both sides between front and rear points. Dimensions should all be within 4 mm otherwise you have a bent or twisted chassis or more problems with bracket positions. Make sure the chassis is flat i.e. not higher one end or the other and not twisted, if you have a poured concrete garage floor this should be accurate within a few milimeters if still not sure go but a laser level, any cheap one will do and check with that.

Ultimately the suspension points need to be as correct as possible in plan and elevation even if they sit in slightly different positions on the chassis tubes to compensate for bending or twisting of the main frame.

Best of luck! If it is of any compensation I am doing that on my self built chassis right now!
