Toe in 9.4 mm

[Janneman]

Whe put a whole lot of shims at the diff side off the driveshafts off my daughters tasmin.
But o horror the toe in is now 9.4 mm and still a camber off -2,15.
Please, is there anyone who knows how we can get those things right?
The local garage and the tyre place do not have a clue.
{They have never seen a TVR before}

Have you check all UJs and rubber bushes are in good condition?

If you have a trailing arm, pre A frame rear end it could be a problem where the trailing arm bolts to the chassis

[Janneman]

All bushes and UJ are new.
Indeed it has a trailing arm, but the trailing arm and pin mount looks good.

Camber is set by shims between the driveshaft and the inboard brake disc. Jaguar XJ6 part. The toe in is set by adjustments on the suspension arm (not the trailing one the other smaller one). Should be an adjuster near the chassis mounting point.

[Janneman]

Thank you very mutch for your reply, I think one day we have a solution,but I am puzzling about the following thing...

A adjuster near the chassis mounting point?
The suspension arm in this car is in one piece, with one fixed hole on the mounting point.
Must I make more holes in the mounting point?
Or must I make the suspension arm adjustable ?
[that is not so hard to do]At least I hope so.
P.S It is a serie 1 tasmin with a separate hub carrier.

Steve, I am not sure I understand your reply either. I thought there were only 2 adjustments on a trailing arm Wedge. Shims on the driveshaft for the Camber and washers on the trailing arm pivot for the toe. I have added adjustable rear suspension arms to mine, but this wasn't standard.

[Janneman]

Hello sevans, that you added adjustable rear suspension arms, is very interesting for me.
Will you please be so kind, to tell me how you managed that.

Bought them from Moore Racing www.moore-racing.co.uk/price.htm They bolt on in place of the originals. These are the arms that go from the differential carrier to the wheel hubs, where the bottom of the shock bolts on.
Not sure you need these to solve your problem though. How many spacers did you put on between the drive shaft and disk? I would remove and check the trailing arm pivots. They get a lot of abuse and are heavily strained. Check the pivots are not bent. If all looks OK then have you tried adjusting the trailing arm by adding removing washers on the pivot. I think one can affect the other so some trial and error may be needed.

I'm digging from my memory a diagram which had some form of adjustment on that second bar. Could be wrong though...

I think it was done to solve the oh my god I'm going to die suspension problems caused by too much power before they realised that the A frames were the way to go. .

[Janneman]

We put 11 shims on each side ,but there is still to much camber.

That sounds like too many to me. I think mine has a couple on each side.Can't help feeling you have another problem here, but not sure what.

[Janneman]

I have just take a quick look under need the car to see off the pivot pin is bent or something.
It seems to be o.k.the rubber looks quite new and there is no trace off wear, beside all that , the car is one week ago mot tested and they find nothing wrong
However , in the wedge bible is a photo of a trailing arm assembly and there is a lot off space between the arm and the mountingplate.
But in our car there is just a very small gap between the two, there are just two small rings in between.
Six washers are on the outside, under the nut on the outside of the car.
I hope that the cure is simple and just a misplace of the washers

[sevans]

Mine has 4 washers each 2mm thick ie 8mm between the chassis and the trailing arm. On the other side of the trailing arm there are two large washers and two small washers and then the nut. This has just been rebuilt and I set it up as per the old set up but this may need adjustment.
Do you have exactly the same problem on both sides of the car?

[Janneman]

We do have the same problem on both side of the car.
And even the measurement are fairly the same.

Jan.

[sevans]

Jan, it's difficult to suggest what may be wrong. I am no suspension expert but if you need that many shimms and it still is not right then I think there must be something else wrong. Is the chassis standard? Is the diff standard? do you have standard disks and drive shafts?
Could you clarify what toe you currently have, what the original camber was, what it is now, how many shimms you added and the affect it had.

[jmorgan]

Forgive me if this is barking up the wrong tree but when I had the 350 trailing arm apart there were a truck load of washers either side. They would seem to affect toe in etc. They were between the arm and dounut bolted to the chassis (sp?). Different number either side. Mine were cut off so as to be popped in and out as required. If memory serves me right (over 40 now so might be talking ollbocks) about 6 one side the other escapes me but not the same as the other.

[york33]

The setup on my trailing arm Wedge has 4 shims on the driveshaft attachment and 4 or 5 washers between the trailing arm and mount. Not had her alignment checked since reassembly but that's how she was before.

[Cathelijne]

A picture of the camber the way it was before we placed the shims.


If I remember correctly, the chassis isn't original but is it an A-frame chassis.

So sorry, but it's my mistake that the vehicel has a A frame .
I am affraid I am tolking nonsense , or If you prefer Double Dutch.
It's mine laque off the noble English lanquage.
And some minor changes off the chassis and something I have read over TVR. And not having the wedge bible at that time.MEA CULPA.Silly old me.
But this punishment of my self is yet enough, I hope.
Sevans;First camber was - 6 and yet it's - 2,10.
Tomorrow I will take the car to a tyre company, with the knowledge I have learned from you all.
Many thanks from my daughter and I.

[sevans]

Jan, all the information I gave was only relevant to a trailing arm chassis. I have never worked on an A frame car so don't know how these are adjusted. Do you know if it was originally A frame or has it been converted?
Hope you get it sorted.
