Rear Beam Question + Video

[GTI6BOY 29]

A couple of questions please about my rallye

 

I am back to square 1 with handling problems now i have changed to a rallye

 

The front is fine, its just the rear beam making the car very unstable.

 

its a fully recon beam with all new parts about 6 months?

 

I would like to know if there is a problem as seen in my vid ?

One more question

 

What is the plug i have found hanging by the fan motor?

 

[welshpug 1,621]

errr, looks like a knackered damper there if it moves that easily, who rebuilt it?

 

what torsion bars are in there?

[GTI6BOY 29]

its a 1.9 beam built by Taylorspug on here

 

The dampers are konis about 6 months old?

[welshpug 1,621]

very odd, no loose bolts? dampers look a bit grotty to be only 6 months old!

[GTI6BOY 29]

hummmm?

 

How can i stop the back skipping around then?

[welshpug 1,621]

how low is it sat? might be hitting the bump stops.

[GTI6BOY 29]

Its not that low at all.

 

 

It feels like the torsion bars dont have much torsion in them so maybe the back of the car is jumping but the beam is staying on the road...?

[welshpug 1,621]

not unknown for the splines to strip in extreeme cases, or where uprated items haven't been hardened properly.

[Miles 331 1 Cars]

That wiring does nothing in our car's so no need to worry about that

 

The damper does look shot or the top bolt/Bolt hole has gone oval, how old are they?

[Alastairh 47]

Konis are generally rather hard even on the lightest of settings.

 

I would be tempted to remove both shocks and see how good they are, and then test the beam. Should soon become clear.

I will drop the shocks off tomorrow and post back my findings

 

cheers

i just replaced the shocks on the rear of my goodwood. the wheel shouldn't move that easy. with shocks on you should struggle to move the wheel up and down with your hands!!

[Jrod 7]

Yep, shocks looked shagged and konis are s*ite anyways so time to get something decent.

[taylorspug 7]

Hello mate, if you dont get anywhere finding the problem and want me to pop over and take a look il be only too happy, seeing as i built the beam and all. It looks like the shocks but it could also be a torsion bar that has stripped/worn. If this turns out to be the case il gladly replace it FOC.

I´m currently rebuilding my beam.

 

Your (worst) problem is not the damper. It looks like at TB wich is destroyed. The missing TB has probably taken the damper shorlty after seesing.

 

Cheers

With the shocks off there is the same movement in the trailing arms.

 

I have adjusted the shocks to the hardest setting and it has got better so im putting my new bilis on the car on sat

 

Thanks very much Taylorspug will let you know how it goes at the weekend

No worries.

With no shocks on there will still be as much movement, that looks like a duff shock to me also. When I had Koni on mine you could barely move the radius arm when it was all built up, compressing the shock was a b*tch to get it fitted.

 

When the car is jacked up, does that arm bounce or just drop right to the floor with no shock on? If it only drops a few mm further than with the shock on then imo the torsion bar is fine & still working.

[GTI6BOY 29]

Yeah drops a couple of mm then bounces when you pull it up

[GTI6BOY 29]

I have put brand new Bilstein shocks on the rear and the problem is the same?

 

Taylorspug is kindly looking at it on sat but in the meantime i took a vid of mine and my mate 205. He has a new refurbed beam set to the same height with new bilsteins also

 

[welshpug 1,621]

odd, its either a torsion bar spline problem or skinny torsion bars.

[pug_ham 240 3 Cars]

Which new billies are fitted & what spec is the rebuilt beam?

 

The UK spec 205 rallye has effectively got an XS beam but it still shouldn't be that soft unless you have bilstein black replacement shocks on imo.

[GTI6BOY 29]

1.9 beam with the b4 kit?

[welshpug 1,621]

What colour are the dampers? B4 is the Streetline Kit.

[taylorspug 7]

The beam was just a std rebuilt item that i did a few months back. The car is being brought over to mine saturday with the intention of getting the problem sorted, so we will find out then, im sure it wont take long to locate the problem once i have the arm stripped out.

 

It seems like it could be a torsion bar issue. I measure up the tbs when i rebuild them so i dont know if its small bars, im certain i havent ever had a complete base model beam in to end up with any of the smaller bars to begin with! Strange one but if it is a problem with the beam il certainly get it fixed as its still well within the 1 year warranty period i give them.
