New torsion bars

[Jimarilo 0]

Hi I am looking for new torsion bars for a 309

 

Apparently they had a different number of splines on the torsion bars (28/30 iic where the later ones have 30/32)

 

Mine is a Mk1 309 .......anyone know where to get them ???

 

If I have more than two people in the car the back goes down and the handbrake gets tight and comes on ........so am guessing the bars are well passed their sell by date and have lost their strength

309 only had one crosstube throughout the range. Apart from gti16 which has different crosstube altogether.

 

What size bars you have currently? Gti are 20mm x 3. 

 

Uprated bars readily available in various sizes. I stock a few different sizes

The splines number problem is only on the 205, all 309 should have the later type bars. Stock diameters are 18.5, 18.7, 19.3 and 20mm.

You can also find cheap Peugeot Partner/405 bars that are often stiffer, look for 1030mm torsion bars with 32/30 splines.

The 309 bars are 1028.5mm so you may need to grind them a bit on the 30 spline side.

If the handbrake is coming on with supension travel you need  new cables , had that with a 205 years ago , on a bump with someone in the back it would try to lock the wheels up , new cable sorted it .

Hi Leslie, thanks for your reply

 

I first thought the rear axles might be seized, but jacked the car up and there is lots of travel on the arms so they are nice and free

 

New hand brake cable sounds the ticket ........many thanks again !!

Thanks for this info, this is very helpful

 

The original bars don't take weight very well so will change them this info will make life much easier

 

Cheers !!

Hey thank you for the heads up ........a good price as well 

 

Just ordered new handbrake cables, all coming together now

 

I run 205 1.6gti wheels which transforms the car and have just put the standard steel wheels back on the front which have snow tyres on. The non turbo diesel is great in the snow. I say I run, but it is the other half's car. My daily is a volvo 940 estate with the 2.4 straight six tdic

 

Thanks again !!
