The big red beast is showing definite "Yank Tank" wallowy ride characteristics. Seems more at rear suspension related than front. I'm pretty sure that it used to be much taunter, by big 4x4 standards anyway, but its hard to evaluate the handling of your own car as one tends to adapt. Doesn't help that the roads round here are terrible for lorry humps and similar vehicle upsetting features running more or less in the direction of travel.
Normally I'd go straight to shock absorbers but new Boge labelled "OEM" units with the correct Land Rover part numbers went on about 15,000 miles ago. Unfortunately I missed putting them in service record spreadsheet so don't know exactly when. When it stops raining I'll verify that there are no leaks but they certainly looked dry on Friday.
Rear Panhard rod got new factory bushes around the same time as the shock absorbers were changed. All the front end bushes, steering assembly bearings et al have been done over the last year except for the front Panhard rod bushes which, according to the MoT man, are in fine fettle but will be done soon anyway as I have new ones. The rear ones were certainly well past their best so the front ones must be showing their age.
I've heard that dying height sensors can give wallow issues. If so what breed to go for. Britcar show genuine Land Rover factory ones at near enough £64 and £67, cheaper than Dunlop or Britpart. Island show Dunlop about £5 cheaper with OEM quality similar prices to what Britcar wants for the factory version. At Britcar prices I'm inclined to go genuine. Obviously if it is likely to be height sensors I'll change the lot. At that age if one is past its best the rest can't be that far behind. if nothing else the arms on the rear ones are looking distinctly manky.
Anything else I should be considering remembering that all the EAS stuff has been done relatively recently. Airbags, compressor rebuild, valve block re-build and so on.
