Land Rover Repair: TD5 Discovery Wheel alignment, discovery wheel, wheel alignment

Question
Hi John
I had a wheel alignment done on my wifes TD5.  The data I have for it states.
Front camber (deg) 0 +/- 0
Front Caster (deg 3.70 +/- 0.10
Front toe in (mm) 2 +/- 1
SAI (deg)  13
included angle (deg) 13 +/- 0.5
TOOT inside (deg)  N/A
TOOT outside (deg) N/A
Rear camber (deg)  -0.17 +/- 0.5
Rear toe in (mm)  0 +/- 0.15
Thrust Angle (deg) 0 +/- 0.15

The front caster angle on the front left wheel was 3.6 degrees which is in tolerance but the front right was 3.2 degrees which is half a degree out or 0.4 of a degree outside tolerance.   The wheel alignment place told me that this cannot be adjusted.  I guess anything can be adjusted but is this something a wheel alignmnet place should be able to adjust?  
regards
Sheridan

Answer
Caster is not adjustable.  If you wanted to change it you'd need to bend a frotn radius arm or install a caster correction radius arm bushing kit.

For half a degree error there is no need to do that.  Many Land Rovers are like yours.

Caster decreases when taller springs are fitted, and as it decreases the truck feels less stabel on the highway.  But you are nowhere close to that, looking at your readings.

Good luck,
