I have a left hand drive Land Rover Defender 90. We have recently changed the Terra Firma 2" lift coils springs sett back to the original as the prop shaft was noisy.
Since then the car slopes to the right (about 2 inches).

We used the following standard coil springs codes:

Blue-Green - Driver side front
Blue-Yellow - Passenger side front
9448 - Driver side rear
9449 - Passenger side rear

Any idea what's the reason for this? Thanks.

 

That could be a number of things , post a before and after pic of your 90 , if your 90 was already lifted , ( before you 2' lift ) the prop shaft angle would be to sharp, for the universal joints , or could be just a universal joint gone bad ... but you should consider a prop shaft spacer if you are going to lift back ..when i see the pics i can further advise ...

what i forgot to mention is Terrafirma has Light Medium & Heavy Applications , the heights will vary depending on the load , if you have a winch ,or winch bumper , its a technical adjustment you have to get right , example for my 90 i need a TF023 Medium Duty Rear , TF018 Medium Duty Front ...

 

land rover always put a bigger spring on the driver side, driver weight i assume.
but it seem some aftermarket company have exaggerated it, a lot of supply house will tell you to just go with the one size.
but ive been wrong before
