trimster Posted March 30, 2017 Report Share Posted March 30, 2017 I have an 1998 466 International 4700. On several recent long trips, bobtail, I notice that the front end shimmies. It is cyclic. It will be totally smooth for a while then cycle into the shimmy. At or below 70mph it's fine. Above 70, it starts. Thought about a steering stabilizer setup. But something is fundamentally off to start this kind of action and a stabilizer would only mask most of the problem I think. Ideas? suggestions...

SWharton Posted March 30, 2017 Report Share Posted March 30, 2017 We had a similar problem but not at speed, just when we were driving at around 35-45 mph and not all the time It ended up being the front end. I don't remember anymore whether it was the shocks or something else. But definitely something to do with the front end. This was on a 2001 IH MDT. We had checked for out of round tires and that wasn't it. Sorry I can't be more specific but it was probably 10+ years ago. Link to comment Share on other sites More sharing options...
Alie&Jim's Carrilite Posted March 30, 2017 Report Share Posted March 30, 2017 I would find a front end truck shop and see what they think. Tires, worn parts, or bent parts can all affect handling and create vibration.

avan Posted March 30, 2017 Report Share Posted March 30, 2017 I had that with my '98 4700 @65 mph. One of the front tires was out of round. Had it shaved and problem resolved.

rpsinc Posted April 2, 2017 Report Share Posted April 2, 2017 Just an out of the box thought. Why would you want to go over 70 in a 4700? Esp while towing. Seems to me like that would be inviting trailer tire failures. Without towing, the truck doesnt have weight to have it ride well. At least that is my experience. Plus, as I posted before, I am still in the working world and when I get in my 4700, ts to go "recreate", so working on learning to RELAX and enjoy the JOURNEY. The destination often will take care of itself when I get there. Marcel Link to comment Share on other sites More sharing options...
trimster Posted April 3, 2017 Author Report Share Posted April 3, 2017 I bobtail at that speed(s). Towing our 36' 5'er...nope. Still, I'd like to get it figured out. Thanks for the input all. I'm off to get the front end and tires looked at.
