One spring in 57 years of motoring isn’t too bad a record. The Disco was all covered by warranty, so inconvenient but not costly to me. It’s springs were okay just the ancillary air kit was very iffy. That’s when I sold it and bought God”s Gift to Caravanners.We have the air suspension on our Jeep. Seems you are not having much luck with rear suspensions?
I’ve had a Pedders coil over kit arrive today and when I get back home at the weekend I will arrange fitting. Like you it wasn’t sensible to fit just one spring as that would restore ride height on one side and the nearside spring would undoubtedly have some “sag” so there would be asymmetric positioning as well as dynamic response. And since I did not know the condition of the dampers it was an easy decision to include their replacement. The car spent it’s first years in Croydon/Wimbledon where there’s lots of mini islands and speed humps far tougher than off roading.I`ve changed enough springs to have paid for my spring compressors several times over. The last one to go, on my 5-series BMW. actually snapped one morning when I opened the drivers door.
Springs should ALWAYS be replaced in pairs (as per dampers), apart from the fact that if ones goes the other will have had similar punishment a new spring will behave differently to one which has been compressed millions of times.
Strange though that the mid life upgrade dispensed with them. Probably cost measures.1999 I had a Renault Laguna Estate with SLS. The on board computer repeatedly told me I had SLS failure. After changing the hydraulic pump and shocks it turned out to be a 50p piece of wire from the sensor to the ECU. Not good!
The Sachs SLS shocks on the Mk1 Sorento were bullet proof . Very clever design , not complicated and worked perfectly.👏
Strange. I have always been told to replace springs and shocks in pairs.On more than one occasion I have been told that there is no longer any need to charge dampers or shocks in pairs. The Jeep dealer and also our local mechanic told us the same.
Maybe not if you have air suspension?Strange. I have always been told to replace springs and shocks in pairs.

Ours is a Jeep and may use the Mercedes system as Jeep is manufactured by Fiat and they may have bought rights to use the system? TBH I don't really know as I am not a mechanic but have to take their word for it.Agreed. Mind you the LR air systems were often replaced because of premature failure rather than wear.
