Fly Boy Posted January 2, 2017 Share Posted January 2, 2017 I have a chimmy in the front end. I had the king pins changed but no luck. It's an 1987 MH 600 and it's still running. Any advice?

j hancock Posted January 2, 2017 Share Posted January 2, 2017 Broken belt in a tire? Bent wheel? Tire out of round? Does it happen only at certain speeds? Are all the spring bushings in good condition? 1 Quote JimIt doesn't cost anything to pay attention.

theakerstwo Posted January 2, 2017 Share Posted January 2, 2017 What he said is were you start first. If it is a shimmy at all speeds then its not worn out parts or a bad shock.Its always good to switch to some know good tires before you go the money route. 2 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/48180-whole-lot-of-shimmying-going-on/#findComment-356872 Share on other sites More sharing options...

Freightrain Posted January 3, 2017 Share Posted January 3, 2017 Even though the king pins were replaced, was it done correctly? Was the vertical clearance checked? I had issues(shake) with my B and I found out the bearing caps needed tightening to get rid of the vertical slop(I replaced the pins about 10 yrs prior). Once I tightened it up again, smooth as glass. 1 Quote Larry 1959 B61 Liv'n Large......................
