Hi Dulcie. Sorry, can't help you with your specific problem but you would do well to avoid describing it as a Jeep as it will get the experts backs up! Only a minor point I know but...  Robin

Had similar with mine even after a full refurb of the compressor. In the end got new Dunlop (hitachi copy) from MM4x4 for about £330 all in and fitted that.

Touch wood (probably jinxed it now) no further suspension faults, up and down like a good 'un. Didn't bother changing to AMK as after all the Hitachi original had done 13yrs and 1400000+ miles before failing so didn't feel the extra expense in swapping it out for the AMK would be worth it. 2006 RRS HSE 2.7 TDV6 (The Baby one as I keep being told)
1999 Discovery 4.0 V8 (Gone but not forgotten)
1997 Range Rover 3.5 V8 (Long gone now)
1966 Series II SWB with RR 3.5 V8 (Never finished, now sold)

thanks matey will be ,getting a new compressor when I check the exhaust wiring and the air tubes just to make sure it is the compressor .I agree that a Dunlop or hitachie might be a sound reliable quality product as the amk I have has only been replaced forty two thousand miles previously and from what I gather in this forum theres two to re calibrate after fitting a different cpmpressor from the original rr one, two meaning amk models and I will match model numbers before buying just to not go through re programming it once fitted it looks as the compressor has been working overtime because there was a load of powder round the pipe in the valve block connection and the pipe was loose.nothing is as simple as just replacing a part on these range rovers but them is absolutely brilliant motors once raite
