Can we eliminate the wishbones before we start taking the body off the chassis? :roll:

Hi Phil,
it was said at start the Wishbones have been checked.
But it was mentioned some thing had been done to the Chassis☺. Ref post 11th Jan.
The Body can be lifted in a W/E and the inside has not been done yet. So i take that as Seats not fitted so not too heavy.

John,

Perhaps you can take some photos from various angles of the suspension and frame of the offending corner (wheel removed) and post them here?

It appears from your original photo that you have Spyder or similar tubular lower wishbones, so very unlikely those would be bent, and even incorrect manufacture that would result in your situation seems unlikely, but still worth comparing them with those on the right side.

Was the car transported to you via trailer? Is it possible the frame/pivots were tweaked by a pull strap or tie down?
It would only take a 5 degree or so tweak to put you off an inch at the wheel center.

I can't find that :roll:

With the Wishbones removed you should be able to see if the Spindle(s) are bent. If my memory serves me correctly the spindles on the Spyder chassis can be replaced.

I would have thought it unlikely that the chassis was twisted or buckled to change the wheelbase by 1" one side without any spindle or wishbone damage? Unless of course it was a major impact & the crash loads were applied directly to the chassis, rather than the wheels or suspension.

[quote="Johnincoventry"] The chassis is new, so I thought the previous owner had assembled the wishbones incorrectly, but having dismantled and rebuilt the suspension, the problem remains"
John you said one of the Screws is not lined up at bottom of Dash Board strange.

[quote="Johnincoventry"]
I have another piece of information which is pointing to a damaged/repaired chassis. Of the two body mounting bolts on top of the tunnel, near the dash, the near side bolt does not line up with the bobbin...........
Clearly chassis needs a closer look at. Maybe it was nicely painted to cover a repair!!!!]"

The dimension between the lower inboard pivots could probably be checked pretty easily without removing the body if the front pivots are a different dimension than the rear then it points to a chassis issue. Loosen the arm nuts, hang a couple plumb bobs over the pivots, and compare front to rear dimensions
