Accumulator and clicking/banging noise 1988 XJ40

Hi Everyone
I have just purchased a 46k mile 1988 XJ40 - 545449
It still has its self levellers and the ride is amazing.

I think my accumulator is low on pressure, nitrogen side, and i am looking to replace it. Is the accumulator the same for the early and later models - i ordered an AC Delco 25528382 type. Mine looks to have a nipple from the valve black that screws into the accumulator itself - but most accumulators ive seen seem to have a male nipple/thread and not female fitting. Any help appreciated

Also I have noticed when the car is loaded there is a banging/heavy clicking sound coming from the passenger side bulkhead area.
I am wondering if its the solenoid valve the feeds fluid to the rear shocks - or just hammer because the accumulator is providing such little cushioning to the system (CBC9702 JAGUAR 98-99 XJ6 UP SOLENOID)

Does anyone know of a replacement self leveller if mine do fail (touch would no leaks and rides amazing)

Thanks
Ian

Hi Ian, I‘ve moved you to the appropriate category, good luck with the car!

Ian,
I see that you are new to Jag-Lovers. Welcome!
Since you have an XJ40, you are on the wrong list. This is the list for the Series I, II, and III XJ6s and XJ12s. The XJ40 was a completely new design and your car has very little in common with ours. Try over on the XJ40 list.

Thanks David. Sorry i thought id clicked the right option.

No worries, happens a lot. You’re definitely in the right place now. And Welcome.

Hopefully it is just that the upper shock bushes that have perished, common fault, cheap and simple job to replace on a non-sls car, not sure about cars with self levelling …

Hi Larry,
Its a hydraulic banging - no noise at the self levellers themselves thankfully. The noise isnt coming from the valve that lets the high pressure into the accumulator nor the accumulator itself. I think its probably the solenoid valve block but i couldnt get to this when i was looking yesterday.
