Seems to be getting worse. Its when i go over bumps and appears to be coming from the suspension/shocks at the rear.
How do you get to inspect them (at the top)? I noticed the newer zeros have a round viewing hole in the boot. This would come in handy to inspect the
bushes etc. I would drill them out but would appreciate if someone could show me a picture to get the holes in the right location.
I have had the car up on a lift and still cant feel anything loose, but its a hell of a noise.

Thanks
Andi

Holes are to make it possible to remove the top damper bolt, provided, that is it it put in from the rear.

They were not included in the original infill panels, but were added after the workshop started cutting them before fitting.

Which dampers, Gaz or other , which donor, Ford or Mazda, and height of chassis frame above ground, where rear wing intersects side of car?

Its got Gaz dampers and its Ford based. Sorry, Not quite sure what you mean by the last bit.
So how do I get to inspect the top bolt?

Thanks

Had the same issue with the same shocks and car. Had to lift the ride height a bit and I've not had a problem since.

Cheers

I would not worry about a visual inspection for the moment.

Check the bolts on the suspension for tightness. it is possible to get spanners on the top bolt in question.

The damper eyes have rubber mounts, so it is unlikely that the noise will be coming from them unless they are worn. If that is the case free play can be felt.

Jack the car and place the chassis on stands it MUST be safe, as you will be moving the vehicle.

place a plank or some sort of lever under the tyre so that it can lift the suspension when operated by another party.

Whilst the the suspension is moved holding various components will indicate if there is any free play.

I suspect that you will not find anything.

with the vehicle on the ground again, take the car for a run, if legal, and when on a flat surface measure the gap between the chassis side, not the floor if lowered floor if fitted, to the ground at a point on the side of the car directly below the front edge of the rear wing and post reading. for good measure take the same measurement at the front reference point which is a point on the bottom of the chassis directly under the rear mount of the front lower wishbone, to the ground. make sense?

Hi Simon,
The front under the rear mount of the wishbone is 11.5 cm and the at the front of the rear wing is 13cm. Is that too low?

Regards
Andi

115 is 5 mm low 130 is normal, with vehicle standing without load, or occupants, however, there is always a however Smile , the difficulty with a light vehicle, is that any load, luggage, tools, driver passenger etc is a greater percentage of the overall weight.

A, rotund driver, such as myself, would compress the suspension a greater amount than someone more, ......... svelte.

So my guess is, you are not compressing the suspension enough, and what you are hearing is the damper going to full extension.

Try putting a load into the boot, remember the tank is below the boot floor,so nothing sharp and see if the problem goes or improves. If it does, lower the ride height to 125 mm at the rear, the 115 at the front will be fine, and see if that sorts it.

Let us know
