- 2001 GMC Sierra - Banging feeling in steering wheel
  
  By Christopher Miller · Posted 13 minutes ago
  
  Good Morning Gents..hope everyone is enjoying a beautiful saturday morning. I have a 2001 GMC Sierra that I bought used in 2018. I am the 2nd owner and its a beautiful truck. Ive put about 60,000 miles on it and recently the front end has felt funny. Kind of loose when hitting bumps adn sometimes I actually feel a "bang" in the steering wheel. I took it to a local guy who said that everything was tight and he tightened the steering box. It didnt feel much better, so I had him replace the front shocks, which had noto been done since I bought it. It had the check enging light on so I took it into a local garage to fix that and check out the suspension. Everything is original and the rubber bushings that I can see look bad. They said everything was tight and there wasnt any play in the front end. Im concerned about the banging feeling in the wheel. Ive been driving this truck for 8 years, so I know how it usually feels and this is something new. Its a second vehicle, so I dont drive it all the time, but Im trying to use it more often. I live out in the country and some of the roads are kind of rough and I alive on gravel roads. Anyone deal with anything like this before?

  Yes of course. There’s no experience in the Trump organization in hiring contractors. it’s not like they’re experienced in that field.😆

  Well, 2 no-bid contracts to donors didn't seem to result in a good job...

  I have a 2020 Sierra with the electronic latch. Can I switch that out and put a regular latch in.

  Yes it’s damn shame what vandalism can do. With defacing, putting chemicals on the grass and possibly including algae in the pool. I’ve taken care of a few pools in my life algae can be a problem. They’re ways to eliminate the problem. I’m sure the problem will be solved. Some people just don’t like nice things. Or is it TDS?
