URGENT - D2a HSE, right front wheel stuck up in wheel arch

[winaje]

Michael2 asked me to post for him, as he's under the pump.

He has a 2004 D2a HSE with ACE (obviously). The right front wheel appears to be stuck up in the wheel arch, even when jacking the chassis off the ground. The left rear airbag is fully inflated also, likely to try and keep it on the ground. He's tried to reset the ACE system with a Hawkeye without success, driven it around, LR rebooted etc.

Has anyone seen this before, and if so, any fix available please?

Have you tried pulling the ace fuse but in saying that with motor off key on solenoid should be in nuetral position.

My only suggestion would be to loosen the two fittings to release oil pressure but be bloody careful of sudden movement of vehicle and of course oil under pressure if that is the cause and before any of this is done and might be a stupid question but is the suspension coil spring ok??

[Michael2]

I've undone the connecting rod for the ACE, removed the tyre, jacked the body and axle independently of each other.

It's not an ACE issue, it's as if the spring has broken, but it hasn't. Just suddenly it can't support the weight of the front corner. But couple that with the Rear LH airbag being up, the RH air bad is not leaking, but sitting in standard position.

Have seen the spring perch torn clean off the rhf chassis rail of a d2a before... the whole lot collapsed. Apparently was a manufacturing / welding flaw. Any chance of pics?

ok, just figured out the larger pic.

release the air out of the left rear air bag see if the front evens out, might be an sls problem

Collapsed shock?
Edit
CJC said it better below!

Collapsed shock?

More like a seized shock (damper), ie locked solid and won't let the spring come back down?

Hi Justin,
Have you seen a few of these happen? I recently saw this on a friend's D2a and didn't know what had caused it. I have pics of it as well. Is it a matter of just getting it repaired properly? 112531

Yes just a proper repair from a bodyworks or someone experienced in chassis repairs. The one i saw has since done 250k and even spent a few years in the kimberley on those roads without a reoccurence.

Yes, that's a Bilstein.

Ok, I've removed the spring, the shock, the shock tower and disconnected the ACE.

Everything at the front corner is good, the shock absorber is as good as the day it went in.

I reassembled the front and looked at the rear air bag.

The Hawkeye showed no faults, and it would not release air from the bag, the bag was hyper inflated.

I removed the wheel, jacked the chassis and the axle, but couldn't undo the air line in-situ.

The SLS valves opened and shut properly when activated through the Hawkeye. I was able to charge the compressor and line and release that air, suggesting a air line blockage between the compressor and the air bag.

Then all of a sudden the Hawkeye managed to deflate the rear airbag.

I took it for a drive and the same thing happened. Now I can deflate the airbag with the wheel on and the car on the ground, but the SLS system doesn't seem to be doing it. The connecting rods (height sensors) all look normal.

I'm trying to sort out my sister's funeral, but need this car for running people around. Any hints toward a quick resolution would be welcome.

Thanks in advance, Michael

long distance diagnostics is always difficult but I would suggest the height sensor is at fault, you could try fitting shrader valves as temporary fix, lots of how to do on this forum search. hope this helps.


also by the look of your pics your in muddy environment try giving the sensor a good clean, has been known to work.

[Michael2]

I removed the Ride Height sensor and cleaned the contacts (they were clean anyway).

No movement (engine running, car stationary) with manipulating the arm. The airbag stayed hyper inflated.

A further interweb search at https://www.landyzone.co.uk/land-rover/disco-ii-air-suspension-%C2%96-the-definitive-guide.61211/ seems to confirm a Ride Height Sensor fault.

A new one has been ordered and should be here in about an hour.

Hopefully that will resolve it.

[Michael2]

Looks like it's now fixed.

Thanks everyone.
