Relative noob here, looking for some advice by those who been in my situation. I read a bunch of posts about AHC mods and OME upgrades.
07 LX470, 180k, been driving the truck for about a year and AHC has been fine until now. I have done only solo trips and no issues. I figure I have 850# over curb weight including my extras, gear, fuel and water, sliders, roof rack, drawer and fridge slide. I read here that factory AHC should be able to raise into H with 4 adults and 350# and I’m in that range until I take my family. But last week on first family trip with wife and child, truck would not move into H, and dropped noticeably (although the L light was not on, I believe it dropped to low mode). When unloaded, it went back into H and stayed there for about 25 mi of rough road. Back home, unloaded it will go into H but I am reluctant to test it far out, especially with wife and 3 year old. The main reason for this vehicle is getting well off the beaten path to remote camp spots with my small family. I’ve spoke to a couple mechanics and received a variety of options.
so, having read here a bunch about AHC tuning and fixes, including LC or king springs...... who here has been able to improve reliability of their AHC with a bleed, new rear springs and tb adjustment?
or, bite the bullet and delete then go with aftermarket lift?
Thanks in advance for your input.
