Reply With QuoteIt's usually the O/S/R spring that sags first in my experience.
Accelerate away from a stop & the torque/load transfers to that spring.

SupporterAnyone have any tips on how to find out which spring has sagged on my 89 classic rangie .
Its sitting down on the drivers side by about 12 mm at the front and around 15 mm at the rear .
The passengers rear seems to be propped up as a result of the irregularity if that makes sense . Maybe its the front drivers pulling down making the pass rear pop up a little .
Should I swap fronts .
Shes done 250,000 klms and I think theyre original springs .

Supporteroff side rear meaning drivers side rear in Australian builds ?

Unbolt and remove either end of both rear shocks and see if that helps even things up. The last time I had uneven stance on a vehicle ( be it RRC or Disco) it has turned out to be the loss of pressure in a gas shock absorber- usually a decent sign that they are on the way out. I know the front shocks are hard to get to, but before you shell out for a new set of springs, at least have a look at the shocks. It's not recommended to swap springs ( providing a previous owner hasn't fooled around with them???). Original springs have a lick of paint on them to signify which spring is which - search paint codes RRC springs and you'll find it.

Yes, drivers side rear.Originally Posted by theg
The D1 received so many customer complaints that LR actually released a bulletin for the fitment of a taller spring to that spot.

It is usually pretty obvious if you put one spring against the other.
Free lengths are here.

There are a few 'urban myths " about springs. The spring rate of a given spring does not change over its life. They do not go "soft"
The spring rate is dependent on wire diameter, wire length, and recently material the spring is made from.
The only reason to change them is if they sag, and the sag refers to free length.

SupporterIn the last fortnight I would say this sag has doubled in its severity .
Could this possibly be as described earlier by (Langy) a gas shock failure . (I dont know if the shocks are gas or oil though at this stage)

Gas shocks - when they are free, they expand and take some effort to compress. They still operate the same, but have gas in them to stop foaming of the oil during heavy use.
Another reason a Disco/RRC sags can be bent radius arms. Check over the bushes as well.

Jack the front of the vehicle up in the middle and see how it sits. Repeat by jacking the back of the vehicle up in the middle.
I had uneven radius arm mounts on my original front axle casing, they caused the vehicle to list to the right with even length springs installed.

SupporterI was thinking the same . If i center the jack under the front and then rear bar I probably will see if its leaning sideways at the front or rear telling me which spring is faulty .
