all the usual fixs done.
Set up.
Donut bushes changed. Both carlton briefly and now genuine vx.
New shocks fitted, both sl and mv6.
New springs fitted.

Where to look next? does Mark dtm have any further ideas? Im thinking suspension arm bushes, after a check everythings done up i guess.
Anyone?

Oh and new tires sports contact 3s fitted, car generally now much better. But still wondering. Old falkens where so bad couldnt tell what was going on.

sounds like rear camber is out forcing the car to tram
i had same problem on mine untill wim adjusted it slightly

[feeutfo]

thanks for reply Andy. I have had that thought also, and could well be the case. One of the rears had worn more on the inside edge very slightly, possibly from changing the bushes?

But on the other hand. The car has been set up 3 times in all, and along with all the other changes, nothing has made any odds to the rear end wondering. Although the car as a whole is a million times better on the new tyres, the only, and now more clear, issue that remains with the handeling is this rear end problem afaict.

Anyway, lets assume a set up is needed. Standard operating procedure is the check everything is ok first.

But what else to check that could be related before
I spend 80 odd quid at wim?
Anything further Ladies and Gents?

As i see it their aint much else that could cause this.....is there?

[Andyb]

what about diff movement

[KillerWatt]

One of the rears had worn more on the inside edge very slightly,

Rear camber for sure if it's wearing odd.

You may have had the car set up 3 times already, but that setup wasn't worth two bob if it was done prior to all the bushes you mention being changed.
If you are happy there is no excess movement anywhere on the car, take it to WIM and get it set up properly.

Make it clear from the start though (as they do tend to "steam in").....tell them to check everything underneath before they even start bolting the sensors on the wheels (because as you say, no point in setting it up if a bush is f**ked somewhere)..

got this on mine under heavy acceleration,(its tweaked quite a bit ) and i think i have narrowed it down to the two mounts that hold the diff, they appear to be very soft/worn, not surprising really(given what it been put through) allowing the whole thing to twist!! just another idea for ya mate!!

[feeutfo]

diff moves all over the place within those diamond(ish)shaped blocks, noticed it when doing the diff bolts back up after changing the springs. BUT at that point it was unloaded, the chassis was on stands so the dif and wheels where hanging from the car rather than the car sitting on them, so assumed that movement would be taken up when the wheels where back on the ground and suspension loaded? Must admit i havent checked any further since and i am a little unclear on my memory of how the rear suspension, diff, and sub frame are bolted on . I get the sub frame arms to donut bushes, and i guess there must be another point the sub frame arms are bolted to
How do i check this? I will refit self level shocks in the morning to make access easier with the wheels on the ground.
Will post a pic in a mo of the dif area.

[feeutfo]

oh ok i think i see it clearer now the sub frame does nt bolt on as such near the diff, it plugs in by the diamond shaped blocks(bushes?)and its those that are bolted on. What do you think?

pic taken when changing atf, so all work done after this was taken, as you can tell by the state of the exhaust/sieve...

[Omegatoy]

thats the kiddies the diff tries to twist side to side on mine, which pulls the rear track arms all over the place i think!!!!
at least they are the worst forwear on mine!! hence leading me to think tey are the culprits!!

Chris: your spring dont seem tobe matched.

Well spotted, your right they didnt, and one was broken, new ones now fitted thanks to SP.32

[Andy Cas]

Guys, I think you need to see the extremes of what your automotive ailment can become. Have a look at this. a rear wheel steer yugo

shameless bump knowing Marks dtm is on line.

[Marks DTM Calib]

Well the rear diff bushes do secure the tail of the subframe. I have wondered about getting some polyurethane and filling some spare ones with it to stiffen them up.

Thanks for reply Mark.

I have the round ones to side of dif, but not the ones rearward of those with the u shared brackets that you have to undo to change the springs(previously refered to as diamond shaped, just been under there to refit self level shocks and they are nothing like a diamond, my memory is def going) maybe you could have a look for me? This is driving me nuts. Esp knowing how well Kevins car drives. His is bog stock mv6 and drives straights as a die.
