The rear suspension on my 1981 early Spirit self levels when loaded, but does not lower when unloaded, and sits high at the rear after carrying 3 passengers and also sits slightly onesided . The suspension will take an overnight stop to lower completely. Any suggestions please. Mark |

Hello Mark, I had the exact same problem on my Bentley 8. It turned out it was a sticky/ rusty cantilever system. The rod that goes up from the suspension spring pod goes into some kind of cantilever system. There is a lever-spring in there that transmits the movement (or better: part of it) to the leveling valve itself, normally there is some protective foam around the spring, alas not in my case. This spring is there to protect the valve from very harsh movements as well as limiting the maximum travel. The rod in the valve itself moves only a few millimeters. If the friction in the cantilever system is higher than the force the spring can transmit, you have the problem you described. In my case the rear left suspension ram extended to the maximum after a few kilometers. I loosened the bolt that goes thru the cantilever block, the rod at the spring pod, sprayed WD40 on everything and worked the linkage with a little help of vise-grip pliers. No everthing works perfect an I could finally adjust the suspension and it stays as it should. |

Mark, I suspect Daniel has hit the nail on the head there. An often missed service item - spray grease into the spring mechanism. |

After a good soaking in WD40 and a thorough coat of spray chain lube both valves are working properly Thanks Mark |
