TP5554

I have a 2022 2500hd LTZ gasser and had the same dreaded low speed (under 35mph) power steering whine since brand new. Sounded like the noisy 1990s Ford power steering units. First, took it back to the dealer with still under 1000 miles on it and they replaced the power steering pump. They claimed it helped but did not entirely fix the problem. Picked it up and did not notice any improvement with the issue. Took it back again and they worked with GM tech support and agreed to replace all the hoses. They claimed the issue is poor and over crimped hoses causing restriction. Fixed the problem and 100% better.
