Just for fun I lubricated the rear springs with something a little different this time.

This cheapo stuff from Scewfix is really thin.


I lifted the car on the frame to open the springs as best I could and shot it in between the leaves. The clear pressurized lube easily blasts straight through the spring and out the other side. For the first few seconds the excess ran out deep red, presumably flushing out iron oxide dust. These 2 year old springs have only done 3.5k and were kept lubricated so an eye opener to see what washed out.

Still weeping after the first run out and the black spring stained red.


I noticed something else too. For a while now I have not been able to slip my original 32mm setting block between the assists and top spring surfaces without forcing it, both gaps had closed by a few mm. However after the run the block slipped in again with ease so something had an effect on the static height. Was it just the benefit of the lubrication? Or could the accumulation of this red debris ‘clog up’ the spring, gradually zapping its strength over time if not removed?

Something I will be watching with interest but for now the old cart springs feel really tip-top and the car a delight to drive.
