They are interchangeable, when I replaced the ones on the 19TZI i fitted normal ones as I wanted a floaty ride! When I fit new ones to the 19TRS I will do the same as theres no point having a non wafty BX!

Would fitting spheres from a GS, CX or DS make much difference to the ride if possible ?

No idea, but it is true that softer BX spheres do the job. The Green Tiger was softer than the TXD, and it wasn't like handling seemed to suffer. Might go for 'comfort' spheres on the TZD at some point, but it's a long way down the To Do list!

The spheres on Stripey are almost as comfortable as those on the Princess... almost. The big difference is that it feels much more nimble and less wallowy, particularly at speed, so I imagine other sportier BXs are a very satisfying combination of comfort and precision.

The TZD is a hooligan*. Every time I go for a more-than-local drive, I sternly tell myself that I'm going to Be Good and drive sedately to save diesel. About five minutes after getting onto the motorway, unless there's speed cameras I'm tearing along at 80-85 :oops: (75-um-very-ish once speedo wobble has been deducted). It's just rude not to :D

*Yes, it's the car's fault. It just shouldn't be so much damn fun to drive.

Same here, i seem to hammer the TZD a lot harder than the n/a diesel Estate but then i seem to hammer all my diesels quite hard.

Mmm...i took my tzd turbo for a run today after putting it all back together, after driving a n/a 1.9 for a few months i can quite agree with the grin factor of a t/d and it drives and feels a lot "tighter" than the n/a. Whilst i prefer the fuel economy and softer ride of the n/a the t/d will be my preference, even tho still not a fast car by any standards i still enjoy the rush of the turbo motor and the cloud of soot it leaves behind. What my tgd needs is a t/d motor id be happy with that.

I drive the TZD and the TGD exactly the same. Under those conditions here are the comprehensive test results;

TZD = goes fast

TGD = doesn't go fast

Although the fitting of illuminated front window switches to the TGD does seem to have improved general all round performance and fuel consumption. This might be subjective though? :shock:

I usually take it steady in the TXD, saves on wearing ear defenders as the noise remains at an acceptable level & fuel economy at 3000 revs in top is nearly 60mpg. But an italian tune up now & again clears the exhaust nicely :)

I wouldn't say the difference with tyres is whether they're budget or not. But yes, some do ride badly and some do ride well.

I agree Kitch, my GT ride is streets ahead of my other 3, although it runs newish Firestone Tyres.
Tim that is a great little shopping list, thanks. Spheres are supposedly fresh, one by the previous owner in Oct/Nov last year IIRC. Goodness knows about the rest of the items though.

Tyres are not amazing; the front two don't match :oops: and are of unknown age but appear in good condition.

I've been reading a bit about strut rebuilding and think my fronts, although not awful, are a little sticky. When dropping from normal to low height, she mostly drops smoothly but there are a couple of sticking points.

i got Pleiades to recon some front struts (from some of their stock) and it was the most marked difference i've ever experienced in improving the ride of a BX, it really gets that dynamic floaty / rolly old citroen ride you imagine you should have. This is on 16 saloon spheres, so some of the softest. Anyway i think with even moderate wear the BX struts can be sticky at normal ride height and can interfere with the suppleness of the whole system. I've experienced that on other BXs.
Signs on mine after strut replacement were the whole car sinking evenly after 24 hours instead of just the back, and the whole car rising evenly into the air when getting out after driving - the way you see the DS do in old French movies!

To achieve this with worn struts i recommend the sucking up of fresh LHM up the strut return pipes trick - a few cycles - to clear out the old dirty sediment filled LHM which can collect that side of the struts.

What you want is the struts moving very freely even with light-medium hand pressure on your bonnet / small imperfections in the road surface. Then tightness of the rest of the setup enables road undulations to be transmitted most efficiently to the sphere as well, meaning less crashy noises. New tight ball joints make a difference.

Another factor i've heard about and suspected with my old TZD estate but never confirmed as we couldn't get at it to replace was a sticky front height corrector - the idea being that there are very small 'damper' holes in the construction of the LHM flow channels in there which can become clogged with sediment, and when i got my 1st BX the LHM was black!
Be wary with Hydraflush as alot of garages warn this can actually dislodge this stuff from the rest of the system, clogging up narrow points like this in the system causing more trouble than before you started! i'd work with fresh LHM before going there.

The BX dash construction can also detract alot from perceived decent ride quality if bits are loose.

I would recommend before recon struts:
1. flush out the struts with new LHM through the return pipes - details somewhere on this site
2. if LHM in tank is murky or dirty, replace with fresh
3. a little 3 in 1 oil onto the front strut chrome shaft through the hole there just under the front spheres (ideally after cleaning the shaft with WD40 and clean rags by putting car into 'high' and lifting up the plastic gaitor over the strut under the front wheel arches)

this should make your struts floaty for a while so you can get to feel a difference in the system - how long will depend on how worn they are/how clean your LHM is. If there is still a problem, check rear arm bearings - sticky ones (on their way out) really interfere with the front ride quality.

this is the joy of getting to know how BXs should drive/ride! :)

Tend to drive the GTi alot more sedately than I did the TZD. Can't afford to drive it any other way. Fun driving is for special occasions :D
