I have previously referred to the fact that at least two or three 6.9s suffer from a lower suspension setting on the right hand front. No one came up with any suggestions, let alone remedies - if there is one. It just so happens that I have in my possession two front struts that were fitted brand new just on ten years ago. I cannot remember where they came from - in fact, a repair shop now no longer in business procured the units but, as I said, from an unknown source.
Examination of both units revealed that both top mounts had slightly squashed rubber components, but more importantly, the right hand unit displayed evidence of external leakage. Now, both struts came from a car with the 'lower' height issue on the right hand (driver's side) side. Further testing seemed to indicate that there was not a lot of 'drag' when pushing and pulling the unit, and this would indicate that the various seals have lost their stickyness. Now, it's been said that these struts are virtually a 'lifetime' job without any maintenance being required, as long as the dust seals are in good condition, and that there should be no external leakage, whilst some internal leakage was acceptable - as long as it'd pass the leak test carried out by disconnecting the thin plastic bleeder line. Surely, the strut cannot last forever, and surely also there must be some deterioration in action and performance which may well lead to slight dropping of the suspension. Anyone any thoughts on my theory, or better still, provide us with a definite answer. Regards Styria
