Hey everybody, this is my first H1 Hummer. I知 looking forward to getting into it and doing some maintenance as well as working out some of the quirks. Right now I知 dealing with tires that are deflating when they池e hooked up to the CTIS. I have one of the large brush guards on the front and it does wiggle a lot side to side making an incredible squeaking noise. I知 guessing the frame is flexing? But I found that hard to believe based on how beefy these trucks are. As well as my airlift hooks I can see moving as I drive down the road. I do get some hood movement and I do want to put in some insulation and sound editing. I replaced the hood bumpers next up is the dog bones. But the tire inflation system has me perplexed.

thx

 

Check the valves at each wheel. I have had leaks there, at the switch, at the CTIS module under the hood and if the hub seals are leaking you can lose pressure. Is it at all 4 wheels, front or rear wheels?

 

Nice ride! those h1s are beasts. Good luck sorting out the issues.
