    do you have self levelling suspension? Sometimes (well I experienced it) the valve can get blocked and you have a lop sided effect. Usually accompanied by an alarm also.....

    thanks michael;.
    Sop it apppears that according to the tables, D/s == Drivers side and P/S = passenger side. And the springs are different lengths.
    So they must have a built in lean.
    Maybe its got something to do with road camber. I thought I read something yonks back about LR and road camber??????

    I had a noticeable 25/30mm lean on Dvr side.
    It was worse after LPG conv when a 30l sil tank was added. I reckon this added 50kg to the right side. I fitted 50 mm lift springs that are not two stage and now it is barely noticeable only 5-10 mm on a bad day.
    Regards

    Have a RR Classic fitted with 2” spring lift (tough dog). From day one right hand rear was lower and rear always visually sat lower. Some measurements on flat ground and relatively loaded showed a difference of around 7mm. I made up some coil spacers, LHR 35mm and RHR 42mm and it now sits a treat.

    Saggy Bum

    I have a 130 crewcab and have a similar problem although I know what caused mine.
    Just after I purchased the vehicle about 5 yrs ago I tore the guts out of one of the rear shockies and had to travel some 300k's back home and wait 3 days for them to get a new set of shockies in. Ever since, that side of the truck sits slightly higher making me believe that the springs have extended slightly (dual rear springs).

    Strange one this. I have a 78 RR and found a 10mm coil spacer in the RH rear, also have an 82 RR with no spacer but a mate of mine has an 84 RR with a 10mm coil spacer in the RH rear.

    lean

    Mine had a lean when i bought it, 97 D1 85,000km's, replaced front springs (pedders), then it sat up at the front so put new back springs as well (ride pro). Now 155,000Km's and 2 years later and slowly starting to drop on the drivers side again.

    betcha it's been like that from the factory
    If you check out the link that HSV Rangie posted, you'll see that the off side springs are 1/2" taller than the near side.

    FWIW, the only time a shock absorber can affect ride height is when it is gas pressurised. The amount of lift is a function of the shaft diameter and the gas pressure. The area of the shaft, multiplied by the gas pressure will give you the amount of 'lifting force'.
