Title: Suspension Nightmare
Post by: David Wilson on 03 May 2011, 21:41:18
Some months ago I had the rear self leveling shocks replaced because they were knackered.  Since then I have had problems getting the rear ride height right, although after some weeks it did seem to settle down.  During this time it wanted to step out on corners even at low speeds but this disappeared.  Having been told to try the ride height level sensor I found it seems to work but the car is still high up.

I measured the distances from the floor through the center of the wheel to the edge of the wheel arches and they are as follows:

n/s/r 68cm, o/s/r 70cm, o/s/f 67cm and n/s/f 65.6cm (although this tyre is pretty worn compared to the others which are about 8 months old.)

To look at it, it looks cockled at the back lol.  Had a word with the mechanic who changed the rear shocks and all I get is excuses about vac pipes - leaks and maybe the sensor being at fault and I have had enough,  >:(
I just want it to be right. 

Also whether or not this is connected the display on the dash has been saying for two weeks something about a low beam fld vision?  I take it this is something to do with the headlights or a sensor?  Can anyone help with either problem because I don't know what to do next?

Thanks.

Dave

Rear N/S trailing arm one sensor, other on front N/S wishbone. Check front first see if the "toggle" arm has popped out of the balljoint

If you have been playing with the ride height sensor ... I hope its the right one ....  the one on the OFFSIDE rear suspension.

If you have been playing with the one on the NEARSIDE rear suspension .. thats the one that does the lights !!!

Check that one (nearside rear) and the one on the front nearside wishbone, if the little arms have "popped off" that gives the described "fld vision" error

HTH  :)

Looking at those ride hights I'd expect some broken springs somewhere...?

I am aware of the sensor on the nearside rear suspension arm because the mechanic who changed the shocks thought that it controlled the ride height.  I have looked at the one of the offside and I am definately looking at the right one.

Broken springs? I will have a look and get back to you.

We checked the springs and there is nothing obvious, the rear pair are fairly new.  Bought a replacement ride level sensor and it hasn't made any difference.  Someone suggested the pump could be faulty? 

Remeasured the heights again and it is 20mm higher at the o/s/r corner compared to the n/s/r where as the front are the same height (I measured it wrong lol).  When I got the car it was that corner which had a knackered shocker.

Completely stumped.   :(

Are both springs for self-levelling :question any ID marks visible :question have you counted the coils

check your front springs as well,a bit missing from the nearside front spring would have the effect of lifting the offside rear of the car slightly.Also when you measure your heights go from wheel centre to arch as that will negate any tyre discrepancies

Right I'll check and get back to you.
