I've just bought a 2001 4.2 diesel Amazon with AHC in Pakistan. The vehicle has 130,000 miles on poorly-maintained Pakistani roads (if the meter hasn't been put back) but seems to have been fairly well cared for. The ride is a bit jarring - a slight shimmy in the steering, and roughness in the ride. The AHC seems to be working fine, as it raises and lowers the vehicle and keeps it level. What can I do to restore it to near-new suspension? Tie-rod ends? Shocks? Steering damper? I'm not yet very familiar with this particular vehicle, nor do I know very much about mechanics generally. Thanks!
