How can test to see if there is a problem with my AHC system other than taking it in for service!

Well the truck has been at lexus since yesterday so I guess they found something wrong with the truck

Locate the resevoir for the system. It should read seven graduations on the tank from high to low. If it is less there are alternatives.

I was at lexus talking with the tech there and we test drove another 2006 LX470 and it was a better ride he told me the only difference were the tire brands and that he has seen this problem before with the tires the ones on my truck are Dunlope and the ones on the other truck are michelin which ride smoother and softer which happens to be the same tires on my old 2006 GX470 which had the nice smoothe soft ride!!

The alignment was off on our 2006 so we only got about 33,000 miles out of the OEM Dunlops. We switched to the Michelins. What a huge difference.

The Michelins are quieter, smoother, have better turn in and while I haven't driven them in the wet or snow yet, have much better brake feel, etc.

My 2 cents... the Dunlops Grandtreks are crap tires.

I second that Crap! how can they put those tires on a Lexus! defeats the purchase of even buying a truck like this!!

I goit the michline tires Latitudes HP but the ride is a little better but still very hARSH when you hit pot holes or man hole the whole cabin rattles!!

I dont think it's the tires anymore they are very smooth and quiet I think it's the suspension maybe the shocks or something? I just cant believe a truck of this caliber rattlelike this when you hit a pot hole or a man hole! this is a lexus! there is a guy two block from me who has the same truck I have been meaning to catch him one day and ask him how his truck rides.it's almost like the shocks are set sport.

which dealership did you take the truck to ? try going to lawrenceville lexus. they're great at listening to you and also trying to tackle the problem. bridgewater lexus comes second to them.

I took it to lexus Of Englewood but I will see about trying Lawrenceville they are like 55 miles away from me I"m in Teaneck NJ.I know it's not the tires it's something with the suspension for sure I will Never Buy a used truck again! even if it's certified like this one!
Thanks I will keep researching someone else must have this problem.
