Piston Slap: Torsion Beam Bump Steer Solutions?

Sam writes:

I have a 2015 Hyundai Elantra SE. It has 25,000 miles and serves its purpose of a street parked commuter car that is comfortable enough for the occasional 600-mile round trip on weekends. The only real issue I have with the car is the cheap-car torsion beam rear suspension. Over large bumps on one side of the car the rear of the car feels like it oscillates extremely in each direction.

In a straight line it is controllable but I worry that in a off ramp taken a little too fast that a unseen bump could actually upset the car enough to lose control (or surprise a fiancé who is used to the handling of a 200S). The 2007 Honda Fit and 2015 Chevy Volt I drove I believe have similar setups but didn’t feel at all like this, and neither did the 2011 Crown Victoria I drove. I’ve read online that some aftermarket replacement shocks would help with this.

Is this really the case? Would a lighter set of wheels also help?

  • Jkross22 When I think about products that I buy that are of the highest quality or are of great value, I have no idea if they are made as a whole or in parts by unionized employees. As a customer, that's really all I care about. When I think about services I receive from unionized and non-unionized employees, it varies from C- to F levels of service. Will unionizing make the cars better or worse?
  • Namesakeone I think it's the age old conundrum: Every company (or industry) wants every other one to pay its workers well; well-paid workers make great customers. But nobody wants to pay their own workers well; that would eat into profits. So instead of what Henry Ford (the first) did over a century ago, we will have a lot of companies copying Nike in the 1980s: third-world employees (with a few highly-paid celebrity athlete endorsers) selling overpriced products to upper-middle-class Americans (with a few urban street youths willing to literally kill for that product), until there are no more upper-middle-class Americans left.
  • ToolGuy I was challenged by Tim's incisive opinion, but thankfully Jeff's multiple vanilla truisms have set me straight. Or something. 😉
  • ChristianWimmer The body kit modifications ruined it for me.
  • ToolGuy "I have my stance -- I won't prejudice the commentariat by sharing it."• Like Tim, I have my opinion and it is perfect and above reproach (as long as I keep it to myself). I would hate to share it with the world and risk having someone critique it. LOL.
