Those of us looking to improve ride comfort have lots of work to do trawling through the many posts we have available on this website. i have been inspired and guided by the many enthusiastic contributors that we have on-board. Am coming up to 500,00 km this week on my one owner 2001 1HDFTE. In the past two years I have replaced engine and transfer case mountings, Lower and upper rear control arms (takes the hula swing out of cornering). One front control arm to reduce the waltzing Matilda tendencies of the front end. Greased and checked balance on drive shaft components (reduces clunk). Replaced fluid and pressure canisters on AHC & adjusted torsion bars (biggest contribution to ride comfort). All jobs that need to be attended to, in order to keep older rigs like ours comfortable and reliable.
